【摘要】 基于川南下二叠统致密碳酸盐岩储层的地质特点，从弹性力学角度出发，通过建立下二叠统碳酸盐岩层力学模型，并以永安场等局部构造为例，介绍了有限无法分析断层应力以及与构造裂缝关系的过程，与钻井成果做了比较。研究成果为定量研究致密碳酸盐岩裂缝发育规律和预测气藏提出了一条新思路。更多还原

【Abstract】 This peper describes the process in which fault stress and its relation to tectonic fractures were analyed with fi-nite element method by establishment of mechanical model of Lower Permia carbonate based on the geologic charac-teristics of Lower Permian dense carbonate raservoir in southern Sichuan and theory of elastic mechanics,and case studies were made by taking some local structures, such as Yonganchang,as examples. Results were then compared to drilling data which provide a new iuea for quantitative study of fracture growth patterns in dense carbonste rock and prediction of gas raservoirs.更多还原
