| 摘 要： | 羌塘盆地主要发育上侏罗统索瓦组,中侏罗统夏里组、布曲组和上三叠统肖茶卡组4套烃源岩。盆地内已发现多处油气显示,主要有3种类型:一类是索瓦组灰岩裂缝中的液态油苗;另一类为南羌塘坳陷隆鄂尼西布曲组和昂达尔错北索瓦组含油白云岩,以及北羌塘坳陷西部西长梁索瓦组含油灰岩、泥质白云岩;第三类为沥青,主要分布在北、南羌塘坳陷西部和中央潜伏隆起东部等地区。通过多种地球化学方法对比,认为索瓦组灰岩液态油来源于索瓦组泥晶灰岩;索瓦组、布曲组含油灰岩、含油白云岩的油苗来源于索瓦组、夏里组泥页岩;盆内许多沥青,则可能来自索瓦组和布曲组灰岩。

| Abstract: | There are 4 sets of hydrocarbon source rocks in the Qiangtang Basin,including the Upper Jurassic Suowa Formation(J3s),the Middle Jurassic Xiali Formation(J2x),the Middle Jurassic Buqu Formation(J2b) and the Upper Triassic Xiaochaka Formation(T3x).Multi points of hydrocarbon show have been discovered in several locations,mainly including 3 types.The first type is the liquid oil seepage in fractures of limestone in the Upper Jurassic Suowa Formation,which was discovered at 114 Daoban,the east of Southern Qian... |
