六盘山盆地西南缘构造与油气勘探潜力分析
|
摘要
六盘山盆地是在古生代褶皱基底上发育起来的中新生代沉积盆地。地面构造调查、地震与非地震勘探表明,喜马拉雅运动以来,在盆地西南缘山带发育由多条逆冲断层及夹于其中的逆冲席所组成的复杂的叠瓦型冲断构造,该构造带与酒西盆地祁连山山前带具有类似的构造特征和油气成藏背景,成藏地质条件优越,是六盘山盆地最有利的油气勘探区之一。
The Liupanshan basin is a Mesozoic sedimentary basin developed on the basement of the corridor transition belt.The surface structure surveys and seismic and nonseismic prospecting indicate that complex imbricated thrust structures consisting of multiple overthrust faults and overthrust sheets intervening in them have been developed in the mountain front on the southwestern margin of the basin since the Himalaya Movement.This structural belt is similar to the Qilianshan mountain front of the Jiuxi basin in the structural feature and the setting for petroleum accumulation.Owing to excellent petroleum geologic conditions,it is one of the most favorable areas for hydrocarbon exploration in the Liupanshan basin.
