It is considered by analyzed results that the forward normal fault trap formed by down-dropped block of fault is combination of inverse-cycle's sendimentary rock; on the contrary, the inverse fault block trap formed by inverse compensation fault is combination of forward cycle's sendimentary rock, which all are prospective area for oil and gas accumulation. It is hoped that the results of the paper can play a reference in other depression exploration.
