摘要
本文在分析和评价川南区域应力场特征、天然气储量≥１．０×１０３ｍ３裂缝系统分布规律及缝洞系岩溶基础上，认为水平担剪应力场主要控制裂缝系统形成和分布。进而建立隐伏裂缝系统成藏模式，阐明在向斜构造和高压区背斜构造中，受较强水平扭剪应力作用的区块，具良好的勘探前景。
Based on analysing and assessing the characteristics of formation stress field,the distribution laws of fractured systems of natural gas reserve≥1. 0 × 108m3,and the karst in systems of fracture and hole in the area of south Sichuan,the paper firmly believes the formation and distribution of rac-tured systems are manily controled by the horizontal shear field. So,sets up reservoir formed patterns of hidden concea] fractured systems and interprets the zones affected by considerable horzontal shear are good explorative prospects in syncline and anticline in the area of high formation pressure.
