摘要
从已钻井资料入手,对高邮凹陷北斜坡辉绿岩石类型、侵入后特征、纵横向分布规律、侵入时期及与油气成藏的关系进行了分析研究。研究表明:辉绿岩在平面上主要分布在北部斜坡的码头庄、大仪集、发财—卸甲庄、沙埝等地区,在纵向上主要分布在阜四段—阜二段(E1f4-E1f2);从与油气成藏的关系来看,侵入E1f2、E1f4的辉绿岩可加速生油岩有机质向烃类转化,是油气良好的封盖层并能形成多种圈闭类型,对油气成藏有利。
Starting from data of drilled wells,it was discussed in this paper to the diabase type,character after invading,vertical and horizontal distribution rules,forming time and its relation to the hydrocarbon accumulation.It is shown that the diabase is mostly distributed in Matouzhuang,Dayiji,Facai-Xijiazhuang,and Shanian area,and intruded in E1f4-E1f2 member,and is favourable for the generation,sealing and trapping of oil and gas.
