摘要
Suqiao-Wenan is the first area in the Bohai Bay Basin where coal-derived hydrocarbon of the Carboniferous-Permian is found. New discoveries have been made till now. In order to clarify accumulation rules of hydrocarbon from the Carboniferous-Permian in the research area, analyses of accumulation background such as secondary hydrocarbon generation of coal source rocks have been made. 3 accumulation models have been concluded. The Ordovician buried hills contacting with the Carboniferous-Permian source kitchen by faults over 300 m wide are the key factors for the 2nd model. Active faults communicating reservoirs with source kitchen control the 3rd model. 3 favorable zones are pointed out for further exploration.
