西西伯利亚东南部上侏罗统地质结构和含油气性(俄文)

Geological Structure and Hydrocarbon－Bearing Property of Upper Jurassic System in the Southeast of West Siberia

对西西伯利亚上侏罗统的石油资源分布进行了研究，并由此得出结论认为，上侏罗统是西西伯利亚东西部最有含油气远景的层位。指出了巴特阶－卡洛维阶－上侏罗统的岩性和地层特征。根据油藏的地层属性对油田进行了分类，划分了三类油田，其油藏分别与Ю11－1，Ю11－2和Ю11－3，Ю11－4层有关。研究了典型油田的结构，论证了进一步扩大区域油气源料基地的地质－地球物理勘探的主要方向。

： Based on study on the oil resources of Upper Jurassic in West Siberia， the paper concluded that the Upper Jurassic is the most favorable zones for hydrocarbon potential in the eastern and western part of West Siberia， identifying the lithology and formation characteristics of Bathonian－ Kallovian－Upper Jurassic． According to the formation attributes of the reservoirs， the oilfields have been classified into three categories， in which the reservoirs are correlatedwith Ю11，Ю12 and Ю13，Ю14，respectively． The paper also made a study in the structure of a typical oilfield， indicating the major geological－geophysical bends for further expanding the regional hydrocarbon resource base．
