摘要
近几年,松辽盆地西部斜坡区重油资源的勘探取得成功,揭示该区仍具有较大的油气勘探潜力,深化对西部斜坡油气成藏规律的认识势在必行。从区域构造、沉积入手,分析油气地质背景。在层序地层格架内,研究储层的纵向发育规律与油气赋存特点,分析含油层与层序界面的关系;在平面上,研究含油砂体的沉积微相构成,总结沉积微相与油气聚集之间的内在成因联系。通过对已知油藏的解剖,总结油气成藏"微相控储,构造控油"的主要控制因素。
In recent years,heavy oil exploration has been successful in the west slope of the Songliao Basin,revealed that great exploration potential still exists and further understanding of the rule of hydrocarbon accumulation is imperative.This paper analyzes the petroleum geology by starting with regional structure and sedimentation.The regularity of vertical reservoir development,the characteristics of hydrocarbon occurrence and the relationship between oil-bearing formation and sequence boundary are studied and analyzed within sequence stratigraphic framework.The sedimentary microfacies of oil sands are studied;the internal relations between sedimentary microfacies and hydrocarbon accumulation are summarized.It is concluded through dissection of the known reservoirs that the key factors controlling subtle reservoir formation are 'reserves controlled by microfacies and oil controlled by structure'.
