西西伯利亚东南部下侏罗统含油气条件及远景

研究了西西伯利亚东南部早侏罗世地层的形成条件和地质结构。在综合解释地震勘探和钻井资料的基础上,划分出36个独立的早侏罗世沉积盆地。详细分析了乌斯季─特姆、科尔托戈尔和纽罗尔沉积盆地早侏罗世砂岩地层的形成条件,对这些地区进行了古地理分析,划分出了最有利的含油气区带,并对具体的含油气远景目标进行了评价。

Petroleum-Bearing Conditions and Prospectiveness of Lower Jurassic in Southeastern West Siberia.

The formation conditions and geologic structures of Lower Jurassic in southeastern West Siberia are studied. Thirty-six isolated depositional basins are classified into according to its composite interpretations of seismic prospecting and drilling data. Detailed studies of conditions for forming such depositional basins as Wuski-Term, Ker-toger and Nurole are incorporated to the paleogeographic analyses of these areas, finding out the most favorable petroleum-bearing areas or zones. Furthermore, some specific prospect target of them are evaluated.
