摘要

针对酒东坳陷营尔凹陷异常高压十分发育的特殊地质环境,利用测井声波资料和地震波阻抗资料研究了营尔凹陷异常压力并建立三维异常压力场。分析研究了营尔凹陷流体压力封存箱的基本特征。从油气分布与异常高压带纵向分布的关系、流体势与油气运聚单元评价等方面,研究了异常高压与油气成藏之间的关系,并从压力发育与油气运移角度对勘探有利区进行了评价。
Ying'er sag in Jiudong basin is characterized by well developed abnormal pressure environment. The distinct geologic characteristic is studied and the 3D abnormal pressure field is established using available sonic logging data and seismic impedance information of Ying'er sag. The feature of the fluid compartment is analyzed. In view of the relations between petroleum distribution and vertical abnormal pressure belt as well as the fluid potential and the petroleum migration and accumulation, the relationship between abnormal pressure and hydrocarbon accumulation is investigated and the favorable targets for petroleum exploration are given.
