摘要
The Glutinite body in steep slope belt in halfgraben-like faulted basin is characterized by poor property of reservoir due to deep burial. But the existence of abnormal high pressure in it allows the reservoir quality to be improved and of significance in hydrocarbon migration and accumulation in this belt. By means of method of lab. analysis, well logging and geological study, the distribution of pressure field of the steep slope belt in the northern Chezhen of Jiyang Depression and the origin of its abnormal high pressure are analyzed, and the relationship between the abnormal high pressure and hydrocarbon accumulation is presented.
