The gradient of the tectonic additional hydrostatic pressure is the main cause of the long-distancemigration of the fluid, oil and gas.
构造附加静水压力梯度是流体及油气长距离水平运移的主要原因。

The main pathway of oil-gas long-distance and large-scale migration consists of two regional unconformity interfaces, two detachment surfaces and two groups of faults.
两个区域不整合面、两个滑脱面、两组断裂是油气长距离、大规模运移的主要通道。
