子北油田早期压裂采用的多是河水或清水做压裂液,后期改用胍胶基液做压裂液,由于压裂液的主要功能就是造缝和携砂,因此,压裂液必须满足一定的性能要求。本文分析了压力液类型,同时对前置液、顶替液、携砂液和总液量进行了分析,分析表明增加压裂液的用量,可以改善储层的压裂效果。
In the early stage of fracturing, the fracturing fluid used in the early fracturing of the North North Oilfield was mostly fracturing fluid of river water or clean water. In the later period, the guar gum base fluid was used to make fracturing fluid. Because the main function of fracturing fluid was to make seams and carry sand, fracturing fluid had to Meet certain performance requirements. In this paper, the type of pressure fluid is analyzed, and the pre-fluid, displacement fluid, sand-carrying fluid and the total fluid volume are analyzed. The analysis shows that increasing the amount of fracturing fluid can improve the fracturing effect of the reservoir.
