| 摘 要： | 东营凹陷南斜坡王家岗地区处于丁家屋子鼻状构造带背景之上，紧邻牛庄生油洼陷，油源丰富，断层—骨架砂体—不整合面相互配置为油气运聚提供了良好的成藏条件。油源对比分析表明，该区存在三种成因类型的原油:北部Ek2~41深部油藏和王古1井奥陶系油藏为孔二段烃源岩提供的原油；而Ek1~21浅部油藏为孔二段和沙四上亚段烃源岩生成的混合型原油；浅层沙河街组油藏主要为沙四上亚段烃源岩生成的原油。对该区深层典型油藏成藏要素分析，认为丁家屋子构造带继承性鼻状构造背景、沙四上亚段—孔二段两套烃源岩和输导体系—圈闭的有效空间配置是油气成藏的主控因素。

| Abstract: | The oil and source rocks correlation shows that the crude oil in this region can be classified into three types.Sources of oil in different horizons vary greatly,the first type crude oil which distributed in the deep reservoirs(Ek2-41)in Kongdian Formation and Wanggu 1 well's Ordovician buried hill reservoirs in the north of Wangjiagang area,and the oil was mainly generated by the source rocks of Kongdian Formation(Ek);the second type oil has geochemiacal features of both the 4th member of Shahejie Formation(Es4)and Ek source rocks in Niuzhuang sag,it was mainly accumulated in the shallow reservoirs(Ek1,21)in Kongdian Formation,and the third type oil which mainly sourced from the upper Es4 source rocks,always accumulated in the reservoirs of Shahejie Formation.According to the analysis of reservoir-forming conditions,it can be seen that the Dingjiawuzi tectonic belt was of good hydrocarbon source conditions;Faults sand-bodies and unconformities which formed the complex solid network paths.The reservoirs of sandstones and unconformities were the main pathway of oil and gas lateral migration,faults played diverting,gathering and connecting role.Dingjiawuzi nose-structural belt geological setting,the favorable combination of hydrocarbon generation,migration,accumulation periods and movement stage of faults and the essential seal of faults are the critical factors for the Kongdian Formation hydrocarbon accumulation in Wangjiagang area. |
