摘要

本文以水－岩作用的观点

从历史的、岩溶的角度

对四川威远构造二叠系阳新统天然气储巢空间一溶隙孔洞系统(以下简称隙洞系统)的演化过程分期(沉积期、暴露期及埋藏期)进行了探讨.大量溶蚀迹象表明阳新灰岩至少发育有沉积型、暴露型及埋藏型三种岩溶.现今阳新统的隙洞系统是岩溶长期作用叠加产物．阳新统储层主要为岩溶控制性储层.

Abstract

In the view of water-rock interaction

the evolution process of the reservoir spaces.of natural gas in the Permian Yangxin Sense of Weiyuan structure

Sichuan Province karst fissure-cave system could be divided into depositional

emergence and burial stages.Abundant karst effected evidences found during the study show that at least three types ofkarst such as depositional karst

emergence karst and burial karst developed in they&ngxin Series. It is proposed by the authors that the present karst fissure-cave system ofthis area is the result of superposition of karst and the reservoirs are mainly karst controlled ones.
