| 摘 要： | 依据华北东部中、新生代盆地叠合过程分析及沉积区与剥蚀区的叠加关系,对华北东部渤海湾地区进行叠合单元划分,并选择处于不同叠合单元的苏桥潜山-文安斜坡、孔西潜山、林樊家凸起等地区,从叠合单元的角度对上古生界烃源岩生排烃史、油气成藏及保存条件进行总结,探讨盆地叠合单元的石油地质意义.研究认为:华北东部渤海湾地区可划分为持续沉降型、复合沉剥型、持续隆剥型3大类型叠合单元,其中复合沉剥型又可分为中沉新剥型、中复新沉型、中复新剥型和中剥新沉型4个次级类型;对于寻找源自上古生界煤系烃源岩的气藏而言,复合沉剥型中的中剥新沉、中复新沉型叠合单元最为有利,若中生代沉积厚度较薄,持续沉降型叠合单元也较为有利.

| Abstract: | Based on the basin evolution and the superposition of deposition areas and erosion areas during Mesozoic and Cenozoic,superposition units of the Bohai Bay area in the eastern North China were classified.Six areas in different superposition units,including Suqiao buried hill-Wenan slope,Kongxi buried hill,Linfanjia uplift,were chosen to study the hydrocarbon generation and expulsion history of Paleozoic source rocks.The hydrocarbon accumulation and preservation of different superposition units were summarize... |
