摘要
为了提高任丘潜山碳酸盐岩油藏的最终采收率,开展了地质、测井、物探、油藏工程等多学科的综合研究,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。通过对控制潜山油藏剩余油分布的地质因素的精细描述,总结出了受不同因素控制的剩余油分布模式有六大类九个亚类,指出受内幕构造和裂缝网络控制的剩余油是今后挖潜的重要方向。
In order to enhance recovery ratio carbonate of buried hill reservoir in Renqiu,a comprehensive research on ge- ology,logging,geophysical prospecting and reservoir en- gineering has been carried out in this paper.It is proposed that the geometric shape of top bed,distribution of interi- or aquifuges and developing degree of fractures in buried hill are the main geological factors for controlling the dis- tribution of remaining oil in the reservoir.Through apply- ing various new technologies and methods comprehensive- ly,the above geological factors are described accurately. The patterns of remaining oil distribution controlled by various factors are classified into six main types and nine subtypes.At the same time,this paper points out the re- maining oil controlled by interior aquifuges and fractures network are the favorite potential regions in the future.
