低渗透油藏渗吸机理及研究状况综述

摘要

概述了低渗透裂缝性油藏中的渗吸驱油机理和规律,并综述了渗吸作用对采收率的贡献方面的研究与应用进展,展望了渗吸液性能研究、室内物理模拟实验对地层条件的真实反映和渗吸作用与采收率之间的定量关系研究等方面的研究前景.%This paper mainly summarizes the research on the oil flooding mechanism and regularity of im-bibition oil recovery in low permeability fractured reservoirs,the research and application progress on the contribution of imbibition to the recovery of oil also be reviewed.At the same time,it prospects the re-search on the performance of the imbibition,the true reflection of the formation condition is simulated in laboratory,the role of imbibition on the quantitative relationship between the recovery and other aspects of the research prospects.
