摘　　要：四川盆地南部长宁地区位于川东-湘鄂西构造带、南部大娄山褶皱带、西部鲜水河-安宁河断裂带的结合带,构造位置处于四川盆地南缘盆山过渡带,受到不同模式的构造变形以及多方向应力场的影响,造成其具有复杂的构造变形特征,影响了页岩气的勘探开发的推进。针对近年来建武向斜区部分构造部位的页岩气井普遍出现低阻、低排气以及井漏现象,开展该地区高分辨率三维地震的精细解释和构造解析,分析其构造成因机制,为页岩气勘探开发的目标优选提供依据。Changning area in southern Sichuan Basin is located in the combination zone of Eastern Sichuan western Hunan Hubei structural belt,southern daloushan fold belt and Western Xianshuihe ANNINGHE FAULT BELT.The structural location is in the basin mountain transition zone in the southern edge of Sichuan Basin,which is affected by different structural deformation modes and multi-directional stress field,resulting in complex structural deformation characteristics and affecting the exploration and development of shale gas The promotion of development.In recent years,the shale gas wells in some structural parts of Jianwu Syncline area generally have low resistance,low exhaust gas and lost circulation phenomenon.This study carried out the fine interpretation and structural analysis of high-resolution 3D seismic in this area,analyzed the structural genetic mechanism,and provided the basis for the target optimization of shale gas exploration and development.
