摘　　要：四川盆地东北部地区位于米仓山和大巴山交汇区,地表复杂的构造形迹表明该地区是多次运动的叠加和改造的结果。文章通过通南巴地区的形变特征研究认为,川东北地区的构造演化先后经历了:印支期构造雏形的产生、燕山期构造定型和喜山期的构造叠加三个演化阶段;结合构造演化与油气运移的匹配关系看,位于开江～梁平海槽边缘的下三叠统北东向构造圈闭具有先期捕获油气的条件,但北西向构造圈闭因为喜山期构造叠加作用对储层的改造,使得这类圈闭具有二次聚集油气的潜力。The Northeast Sichuan basin is on the convergence area of Long men shan and Mi cang shan mountain,it＇s structural forms shows the area han been reformed and superimposed deformation by many times structural movements.According to the analysis of deformation characteristic of Tong Nan ba area,it shows that Northeast Sichuan basin has undergo three structural evolution phase,they are structural embryonic generated phase in Indo Chinese epoch,structural formalized in Yan shan epoch and tectonic overprinting in Xi shan epoch.The north esat direction structural trap,on the boundary of Kai jiang —Liang ping ocean trough ,that formed by Lower Triassic,has the ability to capture oil-gas in early phase,but the north west direction structural trap,also has the potential capacity to capture oil-gas in second time,for the reservoir was been reformed by tectonic overprinting in Xi shan epoch.
