摘要：

本文提出动压办—变容岩溶机理，以探讨碳酸盐岩缝洞系岩溶作用和特征。作者认为构造水平应力场主要拉制缝洞系岩溶强度和分布，缝洞系岩溶作用是造成天然气储层异常高压和天然气富集程度较分散子地质现象的重要因素之一。

Abstract:

In this paper，the mechanism of movable pressure—variable volume karst is provided for the study of the effect and characteristics of carbonate fissure—cavern system karst. The author thinks that horizontal stress field mainly controls the intensity and distribution of fissure—cavern system karst，and fissure—cavern system karst effect is one of the factors that bring about such geologic phenomena as the abnormal high pressure in gas reservoir and the wider distribution of gas concentration.

Key words: Horizontal telluric stress, Solution fissure, Fissure—cavern system, Corrosion effect, Fissure—cavern reservoir
