博乐盆地有利勘探区带优选

博乐盆地油气勘探尚未取得重大进展,急需对其含油气远景进行系统分析。采用野外踏勘、地化分析、地震资料相结合的方法,对博乐盆地石油地质条件进行评价:博乐盆地主要发育三套烃源岩,其中二叠系为主力烃源层系;盆地发育5套储盖组合,石炭系的海相碳酸盐岩及碎屑岩和古近系河流相砂岩为有利储层;构造圈闭主要受逆冲断裂控制,精河坳陷西南部是有利的勘探区带。

Favorable petroleum exploration prospects in Bole basin

The hydrocarbon exploration in Bole basin has not made major progress at present and then systematic analysis of hydrocarbon prospects was needed.Combined with the methods of field survey,geochemical analysis and seismic data,the evaluation on petroleum geological conditions of Bole basin was carried out.The results indicated there were three sets of source rocks in Bole basin,among which the Permian hydrocarbon source rock was the main one,there were 5 sets of reservoir-caprock assemblages,the Carboniferous marine carbonate rocks,clastic rocks and Paleogene fluvial facies sandstone were favorable reservoirs,the structural traps were mainly controlled by thrust faults and the area in southwest of Jinghe depression was the most favorable petroleum exploration prospect.
