摘要
通过定性与定量相结合的研究思路,采用沉积微相、动态监测、油藏工程及数值模拟等方法,总结了乾安油田剩余油分布规律研究的有效做法,明确了乾安油田剩余油分布垂向上仍以主力油层为主,平面上分布在以河口坝为主体的相带内,落实到井网,剩余油分布在油水井排非主流线区域。应用剩余油研究成果,有效地指导了乾安油田的挖潜工作,在确定合理的井网方式基础上,开辟井网调整试验区,取得了较好的调整效果。
Through qualitative and quantitative analysis and by means of sedimentary microfacies,dynamic monitoring,reservoir engineering and numerical simulation,this paper summarized the effective practice of the research on residual oil distribution rules in Qian'an oilfield and clarified that residual oil distributed vertically upward as the main layer,or distributed flatly in the mouth bar or in oil and water wells non-mainstream region based on well pattern.The results had helped guide the development of Qian'an oilfield and had obtained good results in well pattern adjustment test fields based on reasonable well pattern arrangement.
