摘要
吉木萨尔凹陷位于准噶尔盆地东南缘,为有利的生烃凹陷。自二叠系芦草沟组致密页岩油发现以来,已取得一些成果,但研究主要集中在二叠系,石炭系油藏分布规律不清,勘探程度较低。结合该区域钻井,测井,录井、岩心等相关资料,对吉木萨尔凹陷石炭系油源,岩性及储层分布规律进行系统研究,吉木萨尔凹陷烃源岩较好,为自生自储油藏。岩性以火山碎屑岩以及火山熔岩类为主,位于喀尔苏组B段烃源岩发育区之上的三条鼻凸带为油气勘探的有利区带。
Jimusar sag is a favorable hydrocarbon generating sag,which is located in the southeast of east Junggar Basin. We have achieved some results since the discovery of Shale Oil of Lucaogou group Permian,but the research mainly focuses on Permian,formation and distribution of the Carbonic oil deposit is not clear. Combined with the datum of drilling,logging,core and other relevant data,we made a systematic study on the oil source,lithological and reservoir distribution of the Carbonic in Jimusar sag. The study found that,the source rock of Jimusar sag is good,and it’s an authigenic reservoir. The lithology of Jimusar sag is dominated by pyroclastic rocks and volcanic lava,the favorable zone of oil and gas exploration is three nasal protruding belts above source rock development area.
