Widespread slope is the main oil & gas migration direction of simple half graben rift, where developed various hydrocarbon reservoirs including tectonic, lithological and stratum one.
地域广阔的斜坡是简单箕状断陷油气运移的主要指向，发育着构造、岩性、地层等多种多样的油气藏。
While direction of previous main faults that intersect the maximum principal stress by minor Angle also probably becomes the major migration direction of oil and gas.
与最大主应力小角度相交的先期主要断裂的方向也可能成为油气运移的主要方向。
Fault is the main pathway of oil-gas migration in the vertical direction, and unconformity and carrier bed are the main ones of oil gas migration in the parallel direction.
断裂是油气进行垂向运移的主要通道而不整合面和输导层是油气进行侧向运移的主要通道。
