特高含水期油井精细挖潜方法研究

On Fine Potential Tapping Method at Extra High Water Cut Stage

面对特高含水期油井压裂对象逐渐变差、压前含水逐年升高、增油效果逐渐下降的不利形势,在深化潜力研究,搞清现阶段剩余油分布特征的基础上,优选压裂挖潜井、层,并根据措施目的层段油层条件不同,利用目前成熟的压裂工艺,优化压裂方式、层段组合方法以及施工参数,探索提高特高含水期油井压裂效果的有效途径。

Facing with the well fracturing object gradually worse,the water cut increases year by year,the effect of increasing oil production has been reduced gradually,the potential tapping research is deepened,the present remaining oil distribution characteristics are clarified and the fracturing well and layer are optimized.According to the different fracturing layer conditions,the mature fracturing technology,the layer combination and construction parameter are used to explore the effective way for improving the fracturing effect in the extra high water cut period.
