| 摘 要： | 利用已钻井资料及高精度叠前时间偏移三维地震资料,对冀中坳陷文安斜坡基岩结构特征、潜山内幕反射结构和已钻井分析表明,斜坡南段潜山内幕寒武系发育有多套储盖组合,油源来自霸县洼槽下第三系沙河街组和孔店组,大断层面、不整合面和渗透层构成油气运移通道。构建了"坡腹层状古储古堵古盖油气藏"潜山内幕成藏新模式,并发现落实了一批潜山内幕圈闭,优选钻探文古3井,于下寒武统府君山组获得高产工业油气流。回顾了构建潜山成藏新模式和文古3潜山油藏的勘探发现历程,并描述了该油藏的基本特征。

| Abstract: | Based on the analysis of the textures and characteristics of the basement rock,the seismic reflection features of buried hills and drilling and logging data,it is known that three sets of source-reservoir-caprock assemblages develop from the top to the bottom in Cambrian inner buried hills of Wen’an Slop,Jizhong Depression.Hydrocarbon derives from Paleogene Shahejie and Kongdian source rocks and the permeable large fault planes and unconformable planes work as the pathways of hydrocarbon migration.After a new hydrocarbon accumulation model of inner buried-hills is recommended,a group of buried-hill traps were discovered in Wen’an slope.A risk prospecting well,Well Weng’an-3,was elected to drill and high-yielded commercial oil flew was obtained in the lower Cambrian Fujunshan buried-hill carbonate reservoir.The history how to set up the new model and to prospect and discover the Weng’an-3 reservoir is reviewed and the basic characteristics of the reservoir also depicted. |
