摘要
从构造运动的一致性入手,运用构造运动与沉积环境、火山喷发之间的关系,综合各油田对所在坳陷或凹陷的认识,提出渤海湾盆地喜马拉雅运动划分为侯镇幕、济阳幕、东营幕、渤海幕的新观点。指出其在四大沉积期内存在孔二段、沙河街组四—三段、沙河街组一段—东营组三套烃源岩,相比而言沙河街组四—三段的烃源岩分布范围大生烃能力强,整体上具有沉降中心由南向北和由西向东迁移的沉积演化特征。
Based on the conformity of tectonic movement, the relationship between tectonic movement, sedimentary environment and volcanic eruption, and the understanding about depression or sag of each oilfield, the new opinion that the Himalayan Movement of Bohaiwan Basin can be divided into Houzhen Phase, Jiyang Phase, Dongying Phase and Bohai Phase. It is indicated that 3 sets of hydrocarbon source rocks, K2 Member, 4th-3rd Member of Shahejie Formation and 1 Member of Shahejie Formation-Dongying Formation, are existed during 4 sedimentary periods. Comparatively, the 4th-3rd Member of Shahejie Formation distributes more largely with high hydrocarbon generation potential. The sedimentary evolution is featured by the center of subsidence migrating from the south to the north and from the west to the east.
