摘要

The research results of the impact of tectonic stress field, fluid potential, fault plane morphology and its matching relation with attitude of carrier bed to hydrocarbon migration and accumulation show that Jiyang Depression is chiefly from generating sag to the surrounding, mainly NS direction. To Linshang and Xiakou fault zones, fault concave surface of hanging wall, fault convex ridge, convex surface of hanging wall and the ridge formed by carrier bed and fault surface became the dominant migration pathway and direction of hydrocarbon migration and accumulation. The overall performance of oil and gas reservoirs distribution is along the dominant migration pathway and direction as “fruits along the vines”, “flowers along the sticks”. The lateral sealing of fault led to oil-bearing differences in different locations, structural styles differences led to different accumulation modes in different basin structural units.
