水平井修井工艺技术现状分析

水平井结构属于油气田区域开发过程中的一项关键性技术,伴随着石油钻井勘探技术的持续发展与改进,大幅度提升油气资源的产量,显著减少油气田项目开发以及运营的成本,已经成为现阶段的主流需求,水平井设备采用的数量以及种类层出不穷,水平井结构获得大力的推广。不过由于水平井结构井身的轨迹结构具有一定程度的特殊性,其油套管部位更加容易出现磨损甚至腐蚀的情况,故障率高,维修水平井的挑战更加严峻。

Horizontal well structure is a key technology in the process of oil and gas field regional development.With the continuous development and improvement of oil drilling and exploration technology,the output of oil and gas resources has been greatly increased and the cost of oil and gas field project development and operation has been significantly reduced.Horizontal well structure has become the mainstream demand at the present stage.The number and types of horizontal well equipment have emerged one after another,and horizontal well structure has been vigorously promoted.However,because the trajectory structure of horizontal well has a certain degree of particularity,the oil casing is more prone to wear and even corrosion,the failure rate is high,and the challenge of horizontal well maintenance is more severe.
