Condensates and light oils are generally characterized by high maturity, low concentration of sterane and terpane biomarkers and low content of non-hydrocarbon fraction. As a result, some commonly-used sterane, terpane and carbazole migration parameters in conventional oil reservoirs may have a certain limitation in condensate and light oil reservoirs for their poor signal-noise ratios in the gas chromatography-mass spectrometry （GC-MS）. Naphthalene, phenanthrene and their methylated substituents, however, are present in significant concentrations in condensates and light oils. Taking the Fushan depression （in the Beibuwan Basin, Northern South China Sea） as an example, this paper attempts for the first time to use polycyclic aromatic hydrocarbon （PAH）-related parameters to trace migration directions and filling pathways for condensate and light oil reservoirs. The result shows that TMNr （i.e. 1, 3, 7-TMN/（1, 3, 7-TMN ＋ 1, 2, 5-TMN）, TMN： trimethylnaphthalene））, MPI-1 （i.e. 1.5×（2-MP ＋ 3-MP）/（P ＋ 1-MP ＋ 9-MP）, P： phenanthrene MP： methyiphenanthrene）, MN/DMN （∑methylnaphthalene/∑dimethylnaphthalene, %） and MN/TMN （∑nethylnaphthalene/∑trimethylna- phthalene, %） can be used to trace the filling pathways of condensate and light oil reservoirs. These parameters, together with geological consideration and other bulk oil properties （e.g. the gas to oil ratio and density）, suggest that the condensates and light oils in the Huachang oil and gas field are mainly sourced from the Bailian sag that is located to the northeast of the Huachang uplift in the Fushan depression.

Determination of HCH and DDT in soils following Wenchuan 5.12 Violent Earthquake in China

引用

Chinese Journal Of Geochemistry 2011年第1期30卷 125-131页

作者： CUI Weiwei ZHANG Qiangbin ZHU Xianlei WAN Yunyang ZHANG Zhihuan FAN Zhihua wang tieguan College of Geosciences China University of Petroleum Beijing 102249 China State Key Laboratory of Petroleum Resource and Prospecting China University of Petroleum Beijing 102249 China Department of Environmental and Occupational Medicine University of Medicine and Dentistry of NJ-Rutgers University Piscataway NJ 08854 USA

A large number of disinfectants and insecticides were used on a large scale after the Wenchuan 5.12 Violent Earthquake. The disinfectants and insecticides, including HCH (hexachlorocyclohexane) and DDT (dichlorodiphenyltrichoroethane) as representative OCPs, could lead to serious environmental problems. In order to disclose the residues of HCH and DDT in soils following the Wenchuan 5.12 Violent Earthquake, surface soils in Dujiangyan City and Beichuan County were sampled in 2009. The samples were analyzed by GC/MS after pre- treatment by ultrasonic solvent extraction. It has been found that the concentra-tions of γ-HCH, β-HCH and 4,4'-DDT in soils of Beichuan County were 94–102.4, 14.1–36.1 and 2.9–4.3 times high their concentrations in those of the Wolong Nature Reserve, and the concentrations in soils of Dujiangyan City were 52.4–61.6, 8.8 –45.3 and 5.4–6.2 times high their concentrations in soils of the Wolong Nature Reserve, respectively. According to the isomers of HCHs and metabolites of DDTs, it could be concluded that these areas may have additional inputs of lindane and 4,4'-DDT.

The Occurrence of Oleananes in the Beibuwan Basin and Its Application to the Study of Maturity and Oil-Source Rock Correlation

引用

Acta Geologica Sinica(English Edition) 2008年第3期82卷 585-595页

作者： LI Meijun wang tieguan LIU Ju ZHANG Meizhu LU Hong MA Qinglin GAO Lihui State Key Laboratory of Petroleum Resource and Prospecting Earth Sciences and Geoinformatics School China University of Petroleum Beijing 102249 China Southern Oil Exploration and Development Company PetroChina Guangzhou 510640 China Guangzhou Institute of Geochemistry Chinese Academy of Sciences Guangzhou 510240 China

The oleanane parameter, i.e., OP （oleananes/（oleananes＋C30hopanes）） in the two sedimentary columns of the Beibuwan Basin, South China Sea, can be used to delimit the top of oil generation window, with Ro （/%） of 0.53 in Well M1 and 0.55 in Wells H1/Hd1/Hd2, respectively. Comparing with vitrinite reflectance （Ro/%）, the OP features a dynamic range and can indicate the oil generation window more precisely. By using OP and other geochemical indices, the oil-source correlation is also conducted. It suggests that the oils in wells M1 and M2 are derived from the source rocks in situ. The mudstone in Huachang uplift is not the main source rocks for oils in this area, The OP is also a useful oil-source correlation parameter in some Tertiary lacustrine basins.

Characteristics of Oil and Gas Accumulation in Yong'an-Meitai Area of the Fushan Depression,Beibuwan Basin,South China Sea

引用

Petroleum Science 2007年第4期4卷 23-33页

作者： Li Meijun wang tieguan Liu Ju Zhang Meizhu Lu Hong Ma Qinglin Gao Lihui Key Laboratory for Hydrocarbon Accumulation Mechanism Ministry of Education School of Resources and lnformation China University of Petroleum Beo＇ing 102249 China South Oil Exploration and Development Company PetroChina Guangzhou Guangdong 510240 China Guangzhou Institute of Geochemistry Chinese Academy of Sciences Guangzhou Guangdong 510640 China

The Yong＇an-Meitai area is the focus of the present exploration in the Fushan Depression, Beibuwan Basin, South China Sea. All oils from this area are geochemically characterized by higher Pr/Ph ratio, higher proportion of heavy molecular weight hydrocarbons, and higher proportion of C29 regular steranes, which indicate that the organic matter of source rocks might have been deposited in an oxidizing palaeoenvironment and be dominated by higher plant organic matter input. The oil from E3w2 （the second member of Weizhou Fro. of the Oligocene） has a much higher density, relatively higher Pr/nC17 and Ph/nC18 ratios, and a ＂UCM--unresolved complex mixture＂ on gas chromatograms, which indicate that it has been slightly biodegraded. CPI and other terpane and sterane isomer ratios suggest they are all mature oils. The timing of oil charging in E3w2 and E2I1 （the first member of the Liushagang Fro. of the Eocene） determined by the homogenization temperatures of fluid inclusions and thermal evolution history are from 9-3 Ma and 8-3 Ma, respectively. Thus, the interpretation of E3w2 as a secondary reservoir is unlikely. The timing of oil charging is later than that of hydrocarbon generating and expulsion of Liushagang Fin. source rocks and trap formation, which is favorable for oil accumulation in this area. All molecular parameters that are used for tracing oil filling direction decrease with shallower burial depth, which suggests vertical oil migration. The widely occurring faults that penetrate through the source rocks of the Liushagang Fro. may serve as a fine oil charging conduit.

High molecular weight (C_(35)^+) n-alkanes of Neogene heavily biodegraded oil in the Qianmiqiao region,North China

引用

Chinese Science Bulletin 2002年第16期47卷 1402-1407页

Ltd. Tianjin China

With wax content of 1.62%, heavy oil has been produced from the sandstone reservoirs of Neogene Guantao Formation (Ng1m). In the GC and GC-MS RIC profiles of its aliphatic fraction, n-alkanes are totally lost, which shows the result of heavy biodegradedation. However, the remaining trace C13-C36 n-alkanes can be still seen from its mlz 85 mass chromatogram. In addition, a complete series of C35-C73 high molecular weight (HMW) n-alkanes was detected by high-temperature gas chromatography (HTGC). The HMW R-alkane series shows a normal distribution pattern, a major peak at nC43, obvious odd-carbon-number predominance, CPI37-55 and OEP45-49 values up to 1.17 and 1.16-1.20 respectively. The present study not only has conformed the strong resistibility of HMW n-alkanes to biodegradation in crude oils as concluded by previous researchers, but also has provided some significant information on source input and maturity for the heavily biodegraded oil in the Qianmiqiao region.

在全球范围内,西伯利亚、非洲、东欧、印度、阿拉伯、澳大利亚等克拉通,均有中-新元古界至下寒武统原生油气与油气藏的报道,特别是东西伯利亚与阿曼两地,现探明的油气储量业已达到十亿吨级至亿吨级油当量的规模,证明中-新元古界的原生油气仍是一个值得关注的能源资源领域。中国中-新元古界,乃至下古生界,热演化程度普遍处于过成熟状态,不利于液态石油的保存,目前尚未发现其原生油田,但是,在一些地区已发现大量中-新元古界油苗,或大规模的沥青脉,剖析其中-新元古界的含油性,有利于指导中-新元古界原生油气资源的勘探。以扬子克拉通川西北龙门山前山带,以及华北克拉通燕山北部坳陷带为例,由于上覆沉积盖层累计厚度较薄,中-新元古界无深埋经历,或者岩石圈异常增厚,形成"冷圈、冷盆"的地质条件,中-新元古界原生烃类始终处于石油"液态窗"内,仍有利于中-新元古界原生油气资源的保存。

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。

High molecular weight (C_(35)^+) n-alkanes of high-waxy condensate and its source kitchen orientation in the Qianmiqiao burial-hill zone, Bohai Gulf Basin

Science China Earth Sciences 2004年第3期47卷 255-264页

The high-waxy condensate in the Qianmiqiao Ordovician burial-hill zone, Bohai Gulf Basin, North China has been investigated by way of high temperature gas chromatography. As high-mature oil, its high molecular weight wax fraction is mainly composed of C35—C69 n-alkanes with CPI37—55 values of 0.94—1.10. On conditions that core-drilling of source rocks was limited and the exact location of source kitchen is still uncertain in the region, it is inferred that the ori-entation of main source kitchen for the condensate should be on the east of the burial-hill zone, i.e. from the direction of Qikou Sag, according to oil-oil correlation between the condensate and surrounding high-waxy oils as well as lateral distribution of the wax content of crude oils. In addi-tion, it is also further confirmed that the oil filling direction for this condensate reservoir is from NE to SW, i.e. from wells BS-4, through BS-7, to BS-8 based on the analyses of 9 maturity and 3 pyrrolic N-compound parameters.

在济阳坳陷渤南洼陷沙河街组下部发育了一类以泥质灰岩、泥灰岩和泥质白云岩为主的富含有机质的湖相碳酸盐岩。其有机显微组分以矿物沥青基质和沥青质体为主;可溶有机质中饱和烃/芳烃值低,非烃和沥青质含量高;分子标志物的原始生物骨架结构保存好,重排类化合物含量低,有机含硫化合物丰富,并发育诸多特殊类型的标志物。湖相碳酸盐岩所表现出的这些特征与其特殊的沉积环境密切相关,硫酸盐还原菌、绿硫菌、蓝细菌等微生物是该类烃源岩形成的重要物质基础。综合考虑沉积相差异和成熟度的影响,可将二苯并噻吩与菲的比值大于1、重排甾烷及C30重排藿烷极不发育、富含2-甲基藿烷和30-降藿烷系列等条件作为判识湖相碳酸盐岩生油的标志。渤南洼陷湖相碳酸盐岩至少出现过两期生烃高峰,具备形成大规模商业性油藏的能力,可以成为我国陆相湖盆下一步优选的勘探目标。

哈拉哈塘凹陷是近些年的勘探热点地区,为了进一步明确其原油母源输入、沉积环境、成熟度和可能烃源层,对26个哈拉哈塘凹陷和塔河奥陶系原油样品、4个台盆区烃源岩样品进行了系统的芳烃生物标志物分析。研究结果表明,哈拉哈塘原油均具有高萘、高菲、低联苯、贫1,2,5-和1,2,7-三甲基萘而富1,3,6-三甲基萘、高4-MDBT/DBT和(2+3)-MDBT/DBT比值、轻芳烃碳同位素的特点,与塔河奥陶系原油非常相似,反映出其属于典型的海相成因,且以低等藻类和细菌占生源优势。高丰度的二苯并噻吩和较低的DBT/P、Pr/Ph比值,指示其源岩沉积于强还原的碳酸盐沉积环境。等效镜质体反射率Rc1和Rc2揭示哈拉哈塘原油成熟演化处于中等-较高范畴。甲基三芳甾烷异构体组成型式对比表明,中-上奥陶统烃源岩与哈拉哈塘和塔河奥陶系原油对比良好,推测其为本区奥陶系原油的烃源层。
