摘要: 四川松潘-甘孜褶皱带一直是地球科学家关注的一个焦点。近年来, 石油地质学家也对它表现出了很大的兴趣。根据地震测深、重、磁、电等的探查, 发现该褶皱带深部有一低速高导层, 而对大火成岩省-峨眉玄武岩喷溢-地幔柱的认识深化均表明, 四川松潘-甘孜褶皱带是可望获得油气勘探突破的靶区, 重要的是断裂构造、圈闭、储集层的耦合与优化。

Abstract: Songpan-Ganzi folded belt in Sichuan province of China is a major issue to geoscientists. In recent years, petroleum geologists pay more attention to it because of the discovery of a low velocity-high conductive layer in the deep of this folded belt by seismic depth sounding and gravity-magnetic-electric survey. The research of large igneous rock province-Ermei basalt extrusion-mantle plume shows that Songpan-Ganzi folded belt is a hopeful target for breakthrough of petroleum exploration, and the key issue is how to make well a coupling and optimization among its faults, structures, traps and reservoirs.

Key words: Sichuan, Ganzi, mantle, low velocity, petroleum exploration
