摘　　要：英买力地区以往划分出侏罗系,但因证据不足而引发争论。通过对英买1、4、5、6、10等井相关井段岩芯、岩屑观察及古生物样分析,确定该段地层属侏罗系,岩性主要为灰、灰白色砂砾岩,深灰、灰黑色粉砂质泥岩、泥(页)岩夹煤线(层),主要分布在马纳3、英买5、英买10一线及其以东地区,厚度在60-110m之间。The presence of the Jurassic strata in the Yingmaili area,Tabei Uplift,Tarim Basin,is controversial because of the lack of strong biostratigraphic evidence.Our analysis of cores and core cuttings at wells YM 1,YM 4,YM 5,YM 6,and YM 10 shows that the Jurassic strata these wells penetrate Jurassic successions,which consist of grey sandstones,silty mudstone,mudstones and shales intercalated with coal seams.The Jurassic strata occur to the east of the Mana 3,YM 5,and YM 10.Their thickness is between 60m and 110...
