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。
No significant progress has been made in oil and gas exploration in the Bole basin, and a systematic analysis of its oil and gas prospects is urgently needed. The petroleum geological conditions in Bole basin are evaluated by field survey, geochemical analysis and seismic data. Three sets of source rocks are developed in Bole basin, of which the Permian is the main hydrocarbon source. The basin is characterized by 5 Carboniferous marine carbonate rocks and clastic rocks and Paleogene fluvial sands are favorable reservoirs. The structural traps are mainly controlled by thrust faults, and the southwestern part of Jinghe Depression is favorable prospecting Zone.
