摘要
箕状断陷盆地陡坡带的砂砾岩体由于埋藏较深,储集物性普遍较差,通常不能成为油气储集层。但由于异常高压的存在,可使储集物性得到一定的改善,同时对油气运聚也具有积极意义。通过分析化验与测井、地质分析相结合的方法,研究了车镇北带压力场的分布特点,分析了异常高压的成因,进而阐述了异常高压与油气成藏的关系,对于其他地区砂砾岩体的勘探具有一定的指导意义。
The Glutinite body in steep slope belt in halfgraben-like faulted basin is characterized by poor property of reservoir due to deep burial,which can not be served as an effective oil reservoir.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 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.This paper will be significant to glutinite reservoir exploration in other areas.
