摘要
In this paper, large numbers of well-log, tests and geological data in Dongying Depression are used to determine the origin of overpressure. The authors put forward that the oil generation is the major overpressure mechanism based on the confirmation of that the overpressured sediments are normal compaction. It is concluded that overpressures in the reservoir rocks are generated by the fluid transmission from the overpressured source rocks.
