Patterns of arcuate fault block groups and oil-gas accumulation

摘要

In this article, arcuate fault group was discussed. It is one of the most important oil-controlled strike-slip fault groups in oil region of the eastern China. We have also discussed its main characteristic and stress status, built its main pattern and put forward that its oil-gas accumulation is controlled by fault sealing properties, the juxtaposition of sealing layer, reservoir, lap and fault displacement, and so on.
