浅析X区块特高含水阶段水驱油井压裂面临的问题及应对思路
Brief Analysis of the Problems Faced by Hydraulic Fracturing of Water-Flooding Oil Wells in the Extra-High Water-Cut Stage of Block X and the Corresponding Solutions

油井压裂是油井提高产量的重要措施之一，是广泛应用于油田增产稳产的技术手段，为减缓产量递减，改善开发效果作出了重要贡献。但近年来随着油田开发的进行，区块含水不断上升，剩余油分布零散，压裂效果逐年变差，同时套损井数逐年增加，套损井比例高，导致压裂潜力井不断减少，压裂选井选层的难度越来越大。本文简单阐述了X区块进入特高含水期后油井压裂选井选层面临的问题，以及对应的解决思路，对现阶段水驱油井压裂的选井选层问题进行了一定的分析探讨。
Well fracturing is one of the important measures to increase the output of oil wells and is a widely used technical means for increasing and stabilizing production in oil fields. It has made significant contributions to slowing down the decline in production and improving the development effect. However, in recent years, with the progress of oil field development, the water cut in the block has been continuously rising, the remaining oil is distributed in a scattered manner, the fracturing effect has been deteriorating year by year, and the number of casing damage wells has been increasing year by year, with a high proportion of casing damage wells, resulting in a continuous reduction in potential fracturing wells and an increasing difficulty in well and layer selection for fracturing. This paper briefly describes the problems faced by well and layer selection for fracturing in X block after entering the ultra-high water cut period, as well as the corresponding solutions, and conducts a certain analysis and discussion on the well and layer selection problems of water-driven oil wells fracturing at the present stage.
