| 摘 要： | 根据区域构造演化史，采用沉积补偿法研究了川东大池干井构造带下二叠统顶的古构造情况。结果表明，该构造带存在早期古拉张断裂，构造带的形成与这些断裂关系密切。实验室模拟了该类高陡构造带的形成。进而指出了该构造带的有利勘探方法向为：①构造带中断裂发育带的断上盘和下二同地中该统内的溶蚀缝洞系统；②长兴组生物礁发育的有利地区；③池２井以北至池２２井一带５，６号断层之间的陡带石炭纪地层。

| Abstract: | In the light of regional structure evolution history, the palaeostructure conditions on the top of Lower Permian Series of Dachiganjing structural belt in East Sichuan are studied by sedimentary compensationmethod. The result shows that there are early pelaeotension failures in the belt and that the formation of the belt is closely relative to the failures. Through simulating the formation of the high and deep structures in laboratory, it is pointed out that the favourable explorative areas in the belt are the fault upper side of fraucture development region and the karst fracture-vug system in the erosion highland of Lower Permian Series, the favourable region for the reef development of Changxin formation and the abrupt Carboniferous strata betwen No. 5 fault and No. 6 fault in the region from the north part of Chi-2 well to Chi-22 well. |
