摘要
Based on systematic analysis of fault systems and its evolution in Beier Sag, Hailaer Basin, the control of fault formation and evolution on hydrocarbon migration and accumulation was researched. It is concluded that there were four types faults which were early extensional faults, middle tensional-shear faults, early extensional middle tensional-shear long-term active faults and early extensional middle tensional-shear late inverse long-term active faults, and three fault systems which were early extensional fault systems, middle tensional-shear fault systems and late inverse fault systems. Fault formation and evolution controlled formed period, growing types and distributed directions of traps. Long-term active faults were major transporting hydrocarbon fault types in the Beier Sag. Around source-rock, the basement block traps, tilted block and normal drag block traps with controlled by source faults were favorable areas of hydrocarbon migration and accumulation.
