The western edge of Ordos basin thrust nappe structure characteristics and hydrocarbon accumulation

The western edge of Ordos basin tectonic movements are complex,structure types,taking Qingtongxia-Majiatan area conversion zone as a boundary,the western edge of North and South was formed two distinct thrust system.The former control of Paleozoic depositional system and paleogeographic distribution characteristics,and the continental basin tectonic movement strongly influences the Paleozoic strata burial evolution history.Through many times of tectonic movement,the early formation of the fracture by the late tectonic movement and new activities,so that the fault activity has inherited developmental characteristics,fracture activity on the reservoir formation played an important role in controlling.
