摘要
对东营凹陷博兴地区与凹陷中北部的油气成藏特点、油气富集规律及主控因素进行了研究。研究结果表明 ,该区处在凹陷西南边缘的特殊位置 ,其成藏条件不如北部地区 ,纵向上油气主要富集于沙四、沙三层段中 ,平面上主要富集于正向构造带中。油气的富集层位具有东、北部深且相对富油 ,西、南部浅且相对富气的特点 ;天然气主要富集于凹陷边缘外环带。油气藏类型具一定的展布规律。区域构造背景控制了油气运移的指向 ,油气源条件制约着油气的富集程度 ,断层和生储盖配置控制了油气的纵向运移和富集层系。
The formation characteristics of hydrocarbon pools, distribution and main control factors for hydrocarbon accumulation were studied. Because of distinctive geologic background, there are many petroliferous zones vertically, and petroleum was generated mainly in the Sha-3 and Sha-4 of the Eogence. Oil and gas were concentrated in some positive structural units in plane. Petroleum was accumulated mainly in the north and east parts and buried in deep layers, and the natural gas was concentrated in the west and south parts and buried in shallow layers. There are many control factors for petroleum occurrence in the area. The main factors include the geological background, condition of oil and gas source, fault, and regional seal beds.
