The favorable conditions for petroleum accumulation due to volcanic activity and igneous rocks formed during the activity show in two aspects. A The contact surface of igneous rocks and the surrounding sedimentary rocks, like a vertical unconformity surface, formed the conduit of petroleum migration.Petroleum would accumulate once it encountered a trap in which the reservoir had fine porosity and permeability. B It formed a trap barriered by igneous rocks, or changed or cut the original trap.
