| 1 | 盆地内部火山机构的地质模式建立方法及其应用——以松辽盆地南部地区营城组火山岩为例显示文摘在盆地地质背景基础上,根据火山机构的宏观和微观特征,综合运用地质-地球物理等手段,在松辽盆地南部地区建立营城组火山机构地质模式,讨论不同类型火山机构的储层特征。火山机构识别综合利用3类方法:包含地质界面特征、岩性岩相特征、化学成分、喷发方式和单元叠置关系的地质识别,包含自然伽马测井、电阻率测井的测井识别以及包含地震相特征、地震反射特征、地震属性的地震识别。依据以上方法将德惠断陷营城组火山机构分成3类6种,包括流纹质熔岩机构、英安质熔岩机构、安山质熔岩机构、流纹质碎屑岩机构,安山质碎屑岩机构和复合火山机构。针对长岭断陷流纹质不同类型火山机构储层的孔隙度及储集空间类型进行统计,结果表明:复合火山机构的储层物性较好,碎屑岩火山机构的储层物性次之,熔岩火山机构的储层物性较差;酸性火山熔岩机构顶部物性最好,中部物性次之,底部物性最差;火山碎屑熔岩机构在横向上分布较为广泛,在纵向上由多个堆积单元组成。 | 胡佳 王立武 张双杰 皮雄 迟唤昭 刑驰 刘建松 | 2018 | 西安石油大学学报(自然科学版)2018，33，6： | 6 |
| 2 | 松辽盆地南部地区营城组典型火山机构地质特征显示文摘在松辽盆地地质背景研究的基础上,根据盆地南部地区营城组火山岩地质特征对火山机构进行分类,描述其地质特征,并讨论其储层特征。将研究区火山机构分成3类9种,即熔岩类火山机构、碎屑岩类火山机构和复合火山机构3类;熔岩类火山机构包括粗面质熔岩火山机构、玄武质熔岩火山机构、安山质熔岩火山机构、英安质熔岩火山机构和流纹质熔岩火山机构,碎屑岩类火山机构包括玄武质碎屑岩火山机构、安山质碎屑岩火山机构和流纹质碎屑岩火山机构,以及复合火山机构共计9种。并统计了不同类型流纹质火山机构储层的储集空间类型及孔隙度,结果表明:流纹质复合火山机构储集空间类型复杂,储层溶蚀孔缝十分发育,储层物性最好;流纹质碎屑岩火山机构储层溶蚀孔缝较为发育,储层物性中等;流纹质熔岩火山机构储集空间类型单一,储层物性最差。将长岭断陷火山机构内部储层分为高孔高渗型、中孔中渗型和低孔低渗型3类,且有利储层受岩性影响较小,受岩相影响较大。 | 迟唤昭 董福湘 薛晓刚 刘财 司考 | 2019 | 吉林大学学报(地球科学版)2019，49，6： | 5 |
| 3 | Organic-rich formation and hydrocarbon enrichment of lacustrine shale strata:A case study of Chang 7 Member显示文摘Lacustrine shale is an important target for the exploration of unconventional oil and gas in China beyond marine shale gas.However,the formation environment of lacustrine shale differs from that of marine shale,resulting in a different reservoir composition,organic matter,oil and gas content,and hydrocarbon mobility.In this study,the Chang 7 shale of the Yanchang Formation in the Ordos Basin was used to analyze the effect of volcanic activity on the paleoproductivity and preservation conditions during the formation of lacustrine shale.The results show that algae and bacteria were developed before the eruption.After the eruption,the number of bacteria declined,but the increased prosperity of algae reflects that the volcanic activity enhanced ancient productivity.The sulfate generated by volcanic activity promotes bacterial sulfate reduction,and the produced H_(2)S leads to a strong reducing environment in the waterbody,which is conducive to the preservation of organic matter.Organic geochemical analysis shows that the black shale in the shale strata has a high total organic carbon(TOC)content and strong hydrocarbon generation potential,whereas the tuff has a low TOC content and can scarcely generate hydrocarbons,indicating that the tuff deposited by volcanic activity cannot be considered as effective source rock.In terms of storage space,shale is mainly laminar and dispersed,and it includes organic and inorganic pores.The development of organic pores is affected by thermal maturity,whereas inorganic pores mainly occur between detrital particles and crystals.Tuff is mainly supported by heterogeneous matrix and associated with alteration.Its pores include inter-and intragranular mineral pores.The development of tight sandstone pores is affected by compaction,cementation,and dissolution,which mainly consist of intra-and intergranular pores.The Chang 7 lacustrine shale generally contains oil,but different lithologies have different oil drainage efficiencies.Sandstone and shale exhibit the best and worst oil drainage efficiency,respectively.It is mainly affected by the pore size distribution,fluid properties,and rock wettability.Therefore,the development of shale oil should mainly focus on lacustrine shale formations with interbeds.The mutual dissolution of organic matter and hydrocarbons in the shale section leads to the poor mobility and difficult development of hydrocarbons. | Quanyou LIU Peng LI Zhijun JIN Yuewu SUN Guang HU Dongya ZHU Zhenkai HUANG Xinping LIANG Rui ZHANG Jiayi LIU | 2022 | Science China Earth Sciences2022，65，1： | 2 |
| 4 | Paleoenvironment and organic matter enrichment of the Carboniferous volcanic-related source rocks in the Malang Sag,Santanghu Basin,NW China显示文摘Volcanic activity was quite frequent during the deposition of the Late Carboniferous Ha’erjiawu Formation in the Santanghu Basin.The petrology and organic and inorganic geochemical indicators were used to investigate hydrocarbon potential,paleoenvironmental conditions and organic matter enrichment of the mudstones.The results show that the oil generation capacity of the Ha’erjiawu Formation mudstones,which has abundant oil-prone organic matter(TypeⅡkerogen with hydrogen index values mainly ranging from 250 to 550 mg HC/g TOC)in mature stage(Tmax values mainly ranging from 435 to 450℃),is considerable.The Ha’erjiawu Formation was deposited in a dysoxic,freshwater-mildly brackish,and warm-humid environment.During its deposition,the Ha’erjiawu Formation received hydrothermal inputs.The volcanic hydrothermal activities played an important role in the organic matter enrichment.In addition,the total organic carbon(TOC)is significantly positively correlated with the felsic mineral content,but it is negatively correlated with the carbonate mineral content and C27/C29 ratios,indicating that terrigenous organic matter input also contributed to the primary productivity in the surface water.Therefore,the formation of the high-quality source rocks in the Ha’erjiawu Formation was jointly affected by the hydrothermal activity and the terrigenous organic matter input. | Tian-Jun Li Zhi-Long Huang Xuan Chen Xin-Ning Li Jun-Tian Liu | 2021 | Petroleum Science2021，18，1： | 2 |
