| 1 | 不同环境烃源岩和原油中C_(19)~C_(23)三环萜烷的分布特征及地球化学意义显示文摘三环萜烷系列(tricyclicterpanes)普遍存在于不同沉积环境烃源岩抽提物及其原油中。基于不同沉积环境的104件烃源岩和113件原油样品中C_(19)~C_(23)三环萜烷系列化合物分布特征的研究,初步建立了一个关于C_(19)~C_(23)三环萜烷相对百分含量(C_(19+20)TT、C_(21)TT、C_(23)TT)的沉积环境判识图版,利用该图版可以很好地区分海相/咸水湖相、淡水湖相、河流/三角洲以及沼泽相等四种不同沉积环境的烃源岩和原油。进一步研究表明,C_(19)~C_(23)三环萜烷相对含量分布受热成熟度和生物降解作用的影响较小,可作为有效的油-油对比、油-源对比及有机质沉积环境的判识指标。 | 肖洪 李美俊 杨哲 朱志立 | 2019 | 地球化学2019，48，2： | 40 |
| 2 | Oil maturity assessment using maturity indicators based on methylated dibenzothiophenes显示文摘Aromatic fractions of 140 oils and condensates that originated from different types of source rocks(marine shale, terrestrial shale and marine carbonate) were analyzed using gas chromatography–mass spectrometry(GC–MS) to investigate the relative distributions of methylated dibenzothiophenes with respect to thermal maturity. The positions of methyl groups of trimethyldibenzothiophene isomers(TMDBTs) including those used in the definition of maturity indicator TMDBT index in previous studies were firmly identified by co-elution of internal standards in GC–MS analysis and by comparing with reported retention indices. A new maturity ratio related to dimethyldibenzothiophenes(DMDBTs) is proposed on the basis of the differences in thermodynamic stability among different DMDBT isomers. Another maturity index(TMDBT-I2) based on TMDBTs is also suggested on the basis of our empirical observations and presumed thermodynamic stability of TMDBT isomers. These two newly proposed(2,6 + 3,6)-/1,4-DMDBT ratio and TMDBT-I2 correlate well with MDR(4-/1-methyldibenzothiophene) and 2,4-/1,4-DMDBT ratios, suggesting their common chemical reaction mechanisms and similar behavior with increasing maturity. Therefore, they can be effectively applied for maturity assessments. Furthermore, the TMDBTs related maturity parameters are more reliable for over-mature oils and condensates due to the relatively higher concentrations of thermodynamically unstable TMDBT isomers, i.e. 1,4,6-, 1,4,8- and 3,4,6-TMDBT in this study than those of 1-methyldibenzothiophene(1-MDBT) or 1,4-DMDBT. In contrast with 4,6-/1,4-DMDBT, the newly proposed(2,6 + 3,6)-/1,4-DMDBT ratios for oils that originated from different types of source rocks have approximately same relationship with the oil maturity(Rc %). This suggests that the lithology and organic facies may have relatively less influence on(2,6 + 3,6)-/1,4-DMDBT ratio compared to 4,6-/1,4-DMDBT. The maturity parameters based on methylated dibenzothiophenes are particularly useful in the maturity assessments of post- and over-mature oils and condensates and can complement maturity indicators based on steranes and terpanes. | Li Meijun Wang T.-G Shi Shengbao Zhu Lei Fang Ronghui | 2014 | Petroleum Science2014，11，2： | 13 |
| 3 | 石油和沉积有机质中C_(3-)、C_(4-)烷基取代二苯并噻吩的鉴定显示文摘采用人工合成标准物质共注实验、与文献报道的保留指数对比并结合异构体的结构及性质的方法,对石油和沉积有机质中C3-和C4-烷基取代二苯并噻吩类含硫多环芳烃化合物进行了系统的鉴定。确定了常规色谱质谱(GC-MS)分析中,烷基取代二苯并噻吩异构体在HP-5MS(5%-苯基甲基聚硅氧烷)色谱柱上的标准保留指数。确认了前人初步鉴定的部分三甲基二苯并噻吩异构体甲基取代基位置,初步比较了C3-和C4-烷基取代二苯并噻吩在不同成因石油和沉积有机质中的分布特征,初步探讨了C3-和C4-烷基取代二苯并噻吩潜在的地球化学意义。研究结果为今后进一步探索烷基取代二苯并噻吩系列在石油和沉积有机质中的地球化学意义奠定了可靠的基础。 | 李美俊 师生宝 王铁冠 方镕慧 朱雷 | 2014 | 地球化学2014，43，2： | 11 |
| 4 | 油藏地球化学在勘探中的研究进展及应用:以北部湾盆地福山凹陷为例显示文摘基于成熟度梯度和油气运移地色层分馏效应原理,油藏地球化学研究可示踪油气运移方向、优势充注路径、潜在烃源灶方位,从而定位'卫星'油气藏,直接指导油气勘探工作。目前示踪标志物已从传统的咔唑类含氮化合物和甾萜类生物标志化合物发展到含硫和含氧杂原子多环芳烃化合物。南海北部边缘北部湾盆地福山凹陷早期油藏地球化学研究结果表明,位于凹陷中部构造带的花场次凸已发现石油主要来自位于其北东方向的白莲次凹烃源灶,并预测位于花场次凸东部的花东、白莲构造带及凸起往白莲次凹的上游方向最有利的勘探目标区,并得到油气勘探发现和后期的油藏地球化学研究结果证实。精细的示踪参数值等值线图不但确定了油气运移的方向,也预测了优势的充注路径,可直接指导勘探部署。 | 李美俊 王铁冠 | 2015 | 地学前缘2015，22，1： | 8 |
| 5 | 原油中C_(26)-C_(28)三芳甾烷相对含量计算方法及其应用显示文摘三芳甾烷(TAS)是规则甾烷芳构化产物,其中C_(26)-C_(28)三芳甾烷系列稳定分布于原油和烃源岩有机质中。在常规色谱-质谱分析得到的芳烃馏分(m/z 231)质量色谱图上,由于C2620R和C2720S TAS异构体共流出而不能确定3种不同碳数三芳甾烷的相对含量,无法建立类似于C27-C29规则甾烷的相对含量三角图,从而使三芳甾烷在油气地球化学中的应用受到限制。以塔里木盆地台盆区古生界代表性原油样品为例,建立了三芳甾烷相对含量三角图,并用北部湾盆地福山凹陷古近系原油进行了验证。结果表明:该区存在2种不同来源的原油,可以划分为2个不同的原油族群,而来自福山凹陷古近系的原油具有不同的C_(26)-C_(28)三芳甾烷组成特征,原油族群的划分也得到其他分子地球化学证据的支持。在高成熟的轻质油和凝析油中,规则甾烷系列由于浓度低而很难由常规的色谱-质谱分析技术进行检测和鉴定,三芳甾烷由于相对较高的热稳定性而稳定存在,因此可代替规则甾烷用于油-油对比和原油族群划分。 | 张宝收 李美俊 赵青 王铁冠 张科 肖中尧 黄少英 | 2016 | 石油实验地质2016，38，5： | 7 |

| 7 | Helium,Argon and Carbon Isotopic Compositions of Spring Gases in the Hainan Island,China显示文摘Chemical and isotopic compositions have been measured for N2-He-rich bubbling gases discharging from hot springs in the Hainan Island, Southern China. Observed 3He/4He ratios (0.1-1.3 RA) indicate the occurrence of a mantle component throughout the island, which has been highly diluted by a crustal radiogenic 4He component. The occurrence of mantle-derived helium is high in the northern island (12%-16% of total He) and gradually decreases towards southern coast (1%-3% of total He). Such a distribution pattern is most likely controlled by the Pleocene-Quaternary volcanic activities in the northern island and groundwater circulation along the deep major faults. The 40Ar/36Ar and N2/Ar ratios suggest that N2 and Ar of the hot spring gases are mostly meteoric. Although δ13C values of CO2 (-20‰ to -27‰) with low concentrations are consistent with the biogenic origin, the combination of 3He/4He and d13CCO2 suggests a two end-member mixing of mantle and crustal components with CO2/3He ratios of 2×109 and 8×1011, respectively. However, the low CO2/3He ratios (1-22×106) can not be ascribed in terms of the simple mixing but has to be explained by the addition of radiogenic 4He and loss of CO2 by calcite precipitation in the hydrothermal system, which is most likely controlled by the degree of gas-water-rock interaction. | XU Sheng ZHENG Guodong XU Yongchang | 2012 | Acta Geologica Sinica(English Edition)2012，86，6： | 6 |
| 8 | Oil charging history and pathways of the Ordovician carbonate reservoir in the Tuoputai region,Tarim Basin,NW China显示文摘Geochemical analysis of 64 oils sampled from an Ordovician carbonate reservoir in the Tuoputai region was undertaken to study the composition of molecular markers. All the oils have similar geochemical characteristics and belong to a single oil family. They are presumed to derive from the same source kitchen and have similar oil charging history. A histogram of homogenization temperatures(Th) of aqueous inclusions in reservoir rocks shows a bimodal distribution pattern, indicating that the Ordovician reservoir has been charged twice. Coupling the measured Th(°C) with the burial and geothermal histories reconstructed using 1D basin modeling, we relate the homogenization temperature to the relevant geological ages: i.e.,425–412 and 9–4 Ma, corresponding to the Middle to Late Silurian and the Miocene to Pliocene, respectively. The oil filling orientation and pathways are traced using molecular indicators related to alkyldibenzothiophenes and benzo[b]naphthothiophenes. The oil charging orientation is from south to north generally. It can be predicted that the Ordovician reservoirs were sourced from a kitchen located to the south of the Tuoputai region, most probably between the Awati and Manjiaer Depressions. Traps located in the southern side of the Tuoputai region, along the oil charging pathways, should therefore be preferred oil exploration targets. | Rong-Hui Fang Mei-Jun Li Hai-Tao Lü T.-G.Wang Yuan Yuan Yong-Li Liu Zhi-Yong Ni | 2017 | Petroleum Science2017，14，4： | 5 |
| 9 | 分子模拟在油气地球化学中的应用研究进展显示文摘分子模拟采用计算机模拟技术测定分子微观结构、计算体系宏观性质,可以直观再现基于分子和原子水平的不同分子之间的相互作用及化学反应过程,具有研究变量可控、效率高、周期短和安全性高等优点,现已逐渐应用于油气地球化学研究领域。系统总结了分子模拟技术在煤层气吸附机理、页岩气和页岩油吸附、有机质热成熟度评价分子地球化学指标构建、石油运移方向示踪分子地球化学指标建立、有机质生烃及油藏中原油裂解机理等主要领域的研究进展。分子模拟技术具有广阔的应用前景,将在页岩油气等非常规油气勘探、深层-超深层有机质生烃机理、油气运移和成藏等研究领域发挥越来越重要的作用。 | 李美俊 刘晓强 韩秋雅 肖洪 方镕慧 何大祥 高志伟 | 2021 | 石油与天然气地质2021，42，4： | 4 |
| 10 | 甲基二苯并噻吩的吸附性及油藏充注途径示踪机理之Connolly分子表面计算证明显示文摘'地色层效应'是石油运移方向和充注途径示踪的理论基础,其中液-液色谱效应是可能的主要地色层效应之一。输导层中的石油相当于液态流动相,岩石矿物吸附水和束缚水相当于液态固定相。由于石油中不同结构的甲基二苯并噻吩异构体分子与输导层介质吸附作用的差异,异构体化合物的相对含量呈现出规律性的变化,从而可用来示踪石油运移的方向。本文采用Connolly分子表面算法,以半径为1.5?的水分子作为探针,使其分别在目标分子1-甲基二苯并噻吩(1-MDBT)和4-MDBT表面滚动,计算出相应化合物的分子表面积和体积。计算结果表明,1-MDBT分子的表面积为200.21?~2,体积为184.28?~3;4-MDBT分子的表面积为204.32?~2,体积为186.34?~3。与1-MDBT相比,4-MDBT的分子表面积和体积都较大,其与水分子接触的面积也较大。在地层中,石油与水介质之间的接触关系,与实验模拟计算中目标分子与水分子探针的接触类似。与1-MDBT相比,石油中表面积较大的4-MDBT更易于被吸附水和束缚水吸附。此外,4-MDBT的极性略强于1-MDBT,也进一步证明4-MDBT的吸附性更强。因此,随着运移距离的增加,4-MDBT/1-MDBT参数逐渐减小,Connolly分子表面计算结果进一步证明了甲基二苯并噻吩产生'地色层效应'的化学机理。 | 杨禄 李美俊 刘晓强 蒋维东 杨程宇 赖洪飞 亢品 | 2017 | 地球化学2017，46，4： | 4 |
| 11 | 重排藿烷参数示踪陇东地区油藏充注途径显示文摘鄂尔多斯盆地陇东地区延长组长7油层组原油为弱氧化-还原、淡水-微咸水环境下低等藻类与高等植物混源生成,均为成熟-高成熟阶段,属于同一族群原油,且在平面上普遍分布。大部分学者都集中研究原油垂向运移成藏机理,但是对于平面上的充注运移机理则一直少有关注和研究。基于重排藿烷/藿烷(C_(30)*/C_(30)H)比值的热稳定性,分析C_(30)*/C_(30)H参数在表征石油充注运移方面的可行性,认为对于成熟-高成熟原油,C_(30)*/C_(30)H值可能不仅仅是热成熟度的良好响应,对比C_(30)*/C_(30)H参数与MDR参数(4-/1-甲基二苯并噻吩比值)、暴露/屏蔽烷基二苯并噻吩参数,发现C_(30)*/C_(30)H参数与两参数都具有极好的正相关性,表明C_(30)*/C_(30)H参数不仅是良好的热成熟度参数还是良好的石油充注运移参数。利用C_(30)*/C_(30)H参数示踪陇东地区长7油层组的石油充注方向,发现华池地区为主要充注点,向西南、北东方向呈波阵面的方式充注运移,具有连续充注的特征。研究结果初步表明,C_(30)*/C_(30)H参数是示踪石油充注途径的有效参数。 | 李威 文志刚 徐耀辉 朱翠山 高永亮 | 2017 | 石油与天然气地质2017，38，5： | 3 |
| 12 | Distribution and geochemical significance of phenylphenanthrenes and their isomers in selected oils and rock extracts from the Tarim Basin,NW China显示文摘Twenty-two oil samples and eight source rock samples collected from the Tarim Basin,NW China were geochemically analyzed to investigate the occurrence and distribution of phenylphenanthrene(PhP),phenylanthracene(PhA),and binaphthyl(BiN) isomers and methylphenanthrene(MP) isomers in oils and rock extracts with different depositional environments.Phenylphenanthrenes are present in significant abundance in Mesozoic lacustrine mudstones and related oils.The relative concentrations of PhPs are quite low or below detection limit by routine gas chromatography-mass spectrometry(GC-MS) in Ordovician oils derived from marine carbonates.The ratio of 3-PhP/3-MP was used in this study to describe the relative abundance of phenylphenanthrenes to their alkylated counterparts-methylphenanthrenes.The Ordovician oils in the Tabei Uplifthave quite low 3-PhP/3-MP ratios(<0.10),indicating their marine carbonate origin,associating with low Pr/Ph ratios(pristane/phytane),high ADBT/ADBF values(relative abundance of alkylated dibenzothiophenes to alkylated dibenzofurans),low C_(30) diahopane/C_(30)hopane ratios,and low Ts/(Ts+Tm)(18α-22,29,30-trisnorneohopane/(18α-22,29,30-trisnorneohopane+17α-22,29,30-trisnorhopane)) values.In contrast,the oils from Mesozoic and Paleogene sandstone reservoirs and related Mesozoic lacustrine mudstones have relatively higher 3-PhP/3-MP ratios(>0.10),associating with high Pr/Pli,low ADBT/ADBF.high Ts/(Ts + Tm).and C_(30) diahopane/C_(30) hopane ratios.Therefore,the occuirence of significant amounts of phenylphenanthreiies in oils typically indicates that the organic matter of the source rocks was deposited in a suboxic environment with mudstone deposition.The phenylphenanthreiies may be effective molecular markers,indicating depositional environment and lithology of source rocks. | Shao-Ying Huang Mei-Jun Li Ke Zhang T.-G.Wang Zhong-Yao Xiao Rong-Hui Fang Bao-Shou Zhang Dao-Wei Wang Qing Zhao Fu-Lin Yang | 2016 | Petroleum Science2016，13，2： | 3 |
| 13 | 松辽盆地王府凹陷扶杨油层原油充注途径示踪显示文摘基于砂岩油藏充注模式,通过研究油藏内部原油成熟度的微细变化,依据成熟度参数的等值线可以示踪油藏充注的过程,成熟度参数等值线向前最为凸出的部位是石油运移/充注的优势途径。通过研究各项饱和烃成熟度参数,筛选出三环萜烷/17α(H)-C30藿烷,Ts/(Ts+Tm),C30重排藿烷/17α(H)-C30藿烷,C29甾烷ββ/(ββ+αα)等4项不受其他地质因素影响的参数,用于王府凹陷扶杨油层原油运移/充注途径的研究。通过17件扶杨油层原油的研究表明,所有参数均反映出王府凹陷原油成熟度分布规律一致,双32井为原油充注点,其离烃源灶最近;研究区内存在3条优势运移/充注途径,一是自双32井往北东方向充注至双26—双301—双31井区;二是自双32井处,经双38井,往北西西方向充注至长64—长11—长17井区;三是自双32井往北西方向充注至双231—双23井区。 | 蒋兴超 王铁冠 陈践发 冯子辉 王雪 | 2011 | 石油实验地质2011，33，5： | 3 |

| 15 | Petroleum Migration Characteristics in the Northeastern Part of the Baiyun Depression,Pearl River Mouth Basin,South China Sea显示文摘This paper investigates the origin and migration characteristics of petroleum in the northeastern part of the Baiyun Depression,Pearl River Mouth Basin(PRMB).The discovered petroleum in the study area is mainly located in the Lower Zhujiang Member(N_(1)z^(2))and mainly originated from the Enping Formation source rocks in the eastern sag.Active faults(vertical migration)and N_(1)z^(2)sandstones(lateral migration)acted as the petroleum migration systems.The fault activities in the Dongsha event controlled the episodic petroleum migration.Fractures in the fault zones provided effective conduits,and overpressure was the driving force.The vertical migration could not cross the fault zones laterally.The petroleum injection areas in the carrier beds were the contact zones of petroleum-migration faults and carrier beds.The lateral migration was steady-state migration,and buoyancy was the driving force.The migration pathways in the carrier beds were controlled by the structural morphology.Secondary petroleum migration in the study area could be divided into two parts:vertical migration along the fractures in the fault zones and lateral migration through preferential petroleum migration pathways(PPMPs)in the carrier beds.The petroleum migration behaviors,including migrating direction,driving force,and migration pattern,in the faults and sandstone carrier beds were quite different.This study provides a typical example for comprehending secondary migration processes and has great importance for determining future exploration targets in the deep-water area of the PRMB. | ZENG Jianhui WANG Chen GUO Shuai YU Yixin ZHANG Zhongtao YANG Haizhang ZHAO Zhao SUN Rui | 2021 | Acta Geologica Sinica(English Edition)2021，95，1： | 2 |

| 18 | 油气成藏定位研究进展显示文摘在含油气盆地演化史研究中,油气运移是一个复杂的过程,由于遗留下的踪迹较少,难以对其进行模拟,又涉及多个学科,因此油气运移路径示踪一直是油气成藏研究中的难题。油气运聚成藏定位技术,即对油气运移的示踪以及聚集空间分布的预测,是研究油气从生烃、运移、聚集及保存等一系列过程中非常关键的技术,无论是对优选勘探目标、重建油气藏形成演化过程、预测油气富集区,还是对丰富与深化油气成藏理论都具有非常重要的实践意义和理论意义。近年来国内外学者在油气运移方面投入了大量研究工作,取得了丰硕的成果,但是其中部分示踪方法的研究仍是石油地质研究中的薄弱环节,有待进一步探索。基于前人的一些主要成果,对油气成藏定位进行系统梳理和综述,认为油气成藏定位主要经历2个阶段,从定性描述阶段发展到定量刻画阶段,并尝试将油气运移示踪的方法分为4个大类。 | 薛楠 吕修祥 朱光有 韦佳启 汪瑞 李峰 贺涛 吴郑辉 陈晓 欧阳思琪 | 2022 | 天然气地球科学2022，33，1： | 2 |
| 19 | 北部湾盆地福山凹陷原油物理性质及地球化学特征显示文摘福山凹陷是北部湾盆地重要的含油气凹陷,目前已发现的油气田主要分布在环白莲洼陷和皇桐洼陷周缘地区。分析表明,福山凹陷原油具有高API、低密度、低黏度、低含硫量、中—低含蜡量和高饱和烃含量的特征,以轻质油和凝析油为主,为烃源岩在成熟阶段排出的烃类。该凹陷原油饱和烃色谱主要以单峰态前峰型为主,少量为双峰态后峰型,奇偶优势不明显,具有较强的姥鲛烷优势;C27、C28、C29规则甾烷丰度呈'V'字型分布,普遍具有较高的奥利烷含量和较低的伽马蜡烷含量,因此具有相似的来源,母质为藻类与高等植物双重贡献,沉积环境为偏淡水氧化的湖沼环境。根据原油的成熟度和空间分布,可将该凹陷原油划分为2个组群,其中油族Ⅰ主要以东部花场、白莲、花东、红光地区流三段原油为主,具有相对较高的成熟度和奥利烷指数;油族Ⅱ主要以东部花场、白莲、花东地区流一二段和西部博厚-朝阳、美台等地区流三段原油为主,具有相对较低的成熟度。 | 时阳 郭浩 廖飞燕 程刚 李晓寒 | 2020 | 中国海上油气2020，32，6： | 1 |
| 20 | Distribution and geochemical significance of dibenzofurans,phenyldibenzofurans and benzo[b]naphthofurans in source rock extracts from Niger Delta basin,Nigeria显示文摘The distribution and geochemical significance of dibenzofurans,phenyldibenzofurans and benzo[b]naptho-furans in source rocks from Niger Delta basin,Nigeria,were investigated by Rock-Eval pyrolysis and gas chro-matography--mass spectrometry(GC--MS).The data obtained from the source rocks evaluation showed that the rock samples contained type 1/III kerogen capable of generating oil and gas and were within immature to early mature stage.The relative abundance of the Cor,C1-and C2-dibenzofurans range from 1.75%to 29.82%,27.60%to 40.52%and 29.66%to 6889%,respectively.The diben-zofurans were dominated by C-dibenzofurans.Among the C1-dibenzofurans,2-+3-methyldibenzofuran was the most abundant in the rock samples while 1-methy ldibenzofuran appeared to be the least.The relative abundance of benzo[b]naphtho[1,2-d]furan(1,2]BNF),benzo[b]naph-tha[2,1-d]furan(2.1]BNF)and benzo[b]naphtha[2,3-d]fu-ran([2.3]BNF)in the rock extracts range from 12.01%to 52.58%,32.61%to 75.219%and 10.27%to 52.43%.The wide range of values recorded for the three isomers of benzo[b lnapthofurans in the samples suggest source rocks formed from mixed organic matter.Among the pheny ldibenzofuran isomers,4-pheny ldibenzofuran was the most abundant while 1-phenyldibenzofuran was the least.Phenyldibenzofuran ratio-1(PhFR-1)and pheny ldibenzofuran ratio-2(PhFR-2)values range from 0.13 to 1.20 and 0.11 to 2.11,respectively.The resuls showed that the relative abundance of PhFR-1 and PhFR-2 increase gradually with increasing burial depth and maturity(VRo≤0.77%,MPI-1≤0.62.Tmax s 443℃),and have a good correlations with calculated vitrinite reflectance.MPI-I and maximum Temperature(Tmax)-This range of values suggested immature to early mature source rocks.The source rocks were found to have shale and coul lithologics and deposited in a lacustrine/fuvial deltaic settings within immature to early mature stages based on the distribution of dibenzofurans,pheny ldiben-zofurans and benzo[b]naphthofurans in the source rocks.This study showed that dibenzof urans,phenyldibenzofu-rans and benzo[b]naphthofurans were ffcive in deter-mining the origin,depositional environment and thermal maturity of source rocks in Niger Delta basin,Nigeria. | Abiodun B.Ogbesejana Oluwasesan M.Bello | 2020 | Acta Geochimica2020，39，6： | 1 |
