How to think over oil & gas exploration in thrust belt?Firstly,we should discuss the definiton of thrust belt,thrust fault,overthrust belt,reversed fault and overthrust fault and their differences,and then analyze the causes of formation and mechanisms as well as the tectonic background.
如何看待冲断带油气勘探,首先要讨论冲断带、冲断层、掩冲带、逆断层、逆掩(或掩冲)断层的定义及其差异,然后分析冲断带的成因机制和形成的大地构造背景,冲断带油气勘探的兴衰历史。
In compress-shear oil and gas bearing basin exploration, early exploration is concentrated on the high position of fault-fold structural zone, many fault-anticline, fault-nose hydrocarbon reservoirs are found, but with the deepening of exploration, the fault trap formed by the reversed fault and convergent torsion fault of these fault-fold structural footwall has to be considered.
