Optimization of frac imbibition process system in Lamadian oilfield

Abstract

The most effective way to develop oil fields is hydraulic fracturing. During the development process, it is found that the shut-in time after fracturing has a great impact on crude oil production, and the analysis believes that imbibition is the main reason. Therefore, it is necessary to study the influence of hydraulic fracturing on the imbibition law of oil reservoir, give full play to the imbibition function, and improve the development effect of oil field. In this paper, the relationship between imbibition and post- fracturing shut-in time and imbibition rate and post-fracturing shut-in time is studied, and on this basis, the production system is optimized and the limit shut-in time is determined.
