水平井完井工艺技术研究与分析

最近十多年,水平井的应用越来越多,逐渐由简单的射孔完井发展为筛管完井、砾石充填完井、分段防砂、分段压裂完井和分段控水完井等多种配套完井技术。本文针对当前常用的水平井完井方式进行了研究,对其中存在的不足和可提高的部分进行了分析总结,给出了改进的方法和方案,为相关井型的相关研究和现场应用提供参考作用。

In recent ten years, the application of horizontal well is becoming more and more and gradually has developed fiom a simple perforation completion for screen completion and gravel pack completion and sand control and fiacturing completion every block and a variety of facilities, such as section water control completion well completion technology.This article in view of the current commonly used horizontal well completion methods are studied, on the part of the deficiencies and to improve the analysis sulnmary, gives the improving method and scheme, for the well type related to provide reference to the relat- ed research and field application effect.
