摘要
Abstract
The reservoir pore structure is the critical element which has great effect on oil displacement efficiency.Through various core analysis and tests,the reservoir of lower Karamay formation in the Middle District No.6 of Karamay oilfield has been classified into four categories.The features of pore configuration and oil displacement efficiency of each type are analyzed in this paper.The typeIreservoir has relatively high textural maturity.Low permeable core in this type has the highest oil displacement efficiency about 62%.The oil displacement efficiency of the type II reservoir varies in a large range,the average value is about 50.5%.The oil displacement efficiency of the type III reservoir varies in a large range,the average value is about 42.54%.Its average pore throat radius is relatively short.The pore throat distribution curve of the type IV reservoir is single peaked and relatively thin state and its oil displacement efficiency is 35%.关键词
