摘要：

四川盆地中西部上三叠统砂岩的裂缝控制了流体的储集与渗滤能力。裂缝为非构造作用成因,由差异压实作用、溶蚀作用、岩溶陷落作用及重力滑动作用形成。古残丘的高部位和较高部位是非构造裂缝网系最发育的地方,也是布置探井和开发井的理想位置。

Abstract:

The fractures in Upper Triassic sandstones in middle west ares of Sichuan Basin has controlled the reservoiring and penetration of fluids.The fracture forming mechanism in Upper Triassic of the area is mainly nontectonic origin,including differential compaction,corrossion,karst collapse and gravity sliding.The top and upper parts of paleo unaka are favourable places for nontectonic fracture system,thus they are perfect places for both test wells and development wells.
