摘要:

本文对川南地区地层岩性组合、构造形迹及其受力分析的基拙上,研究了向针中存在的三种储集空间,即向针转折端发育的追踪张裂缝为主千的裂缝网络、向针深部转折端的脱项现象造成的储集空间及低渗层原有的连通孔洞缝。本文进而探讨了形成向针裂缝型气藏的三个阶段,即早期聚集、改造成藏及平衡稳定阶段,指出在川南这个特定地区向抖是天然气勘探的新领域。

Abstract: According to the lithological association, structural configuration and the lithomechanical analyses, the author distinguished the synclines in Southern Sichuan into three kinds of reservoir space, that is, the gapping fissure networks in syncline bowls, the decollement in deep syncline bowls and the connate connected pores in the low pervious beds,The paper further discussed the three development stages of synclinal fissure reserovirs,which are the early congregation stage, the reformation stage and the stable stage,and pointed out that it is the synoline that is the new natural gas exploration target in Southern Sichuan.

Key words: Natural gas exploration, Syncline, Southern Sichuan
