川西拗陷南段香溪群的天然气成藏模式及勘探目标

Pool-formed Modes of Natural Gas in Xiangxi Formation in the South Section of West Sichuan Depression and the Exploration Targets

本文通过对川西拗陷南部已知气田和含气构造成藏地质条件的深入分析,建立了天然气成藏的三种地质模式,据此对该区主要构造区带和局部圈闭的含油气地质条件进行了评价,并预测了勘探方向和目标。

Through a profound analysis for the pool-formed geological conditions of the known gas fields and gas-bearing structures in the south part of West Sichuan Depression, three geological modes of forming natural gas pools are set up in this paper. Based on these, the oil and gas-bearing geological condition are evaluated for the main structural areas and zones and regional traps. The exploration trends and targets are forecasted also.
