任丘碳酸盐岩潜山油藏剩余油分布研究

Study on the remaining oil distribution of carbonate buried hill reservoir in Renqiu

根据动态和静态资料综合分析结果 ,提出目前控制潜山油藏剩余油分布的地质因素主要有潜山顶面几何形态、潜山内幕隔层分布和潜山裂缝的发育程度。通过综合应用多种新技术、新方法 ,对控制潜山油藏剩余油分布的各种地质因素进行了精细描述 ,总结出了受不同因素控制的剩余油分布模式 ,根据剩余油的分布类型 ,提出了潜山油藏剩余油潜力的分布和挖潜方向。

According to the comprehensive analysis of reservoir dynamic and static data, it is proposed that the geometric shape of top bed, distribution of interior restraining barrier and developing degree of fractures in buried hill are the main geological factors for controlling the distribution of remaining oil in the reservoir. Through applying various new technologies and methods comprehensively, the above geological factors are described finely. The patterns of remaining oil distribution controlled by various factors are summarized. On the basis of the types of remaining oil distribution, the regions and future direction for tapping the potential of the reservoir are put forward.
