摘要
在钻井工艺不断优化完善的过程中,大位移井钻井技术的应用也更加普遍。在大位移井钻井作业的过程中,要想保障操作的安全性和高效性,就要重视井眼轨迹设计。在实践操作的过程中,主要存在井眼难以清洁、井壁稳定性较差以及管柱严重弯曲等问题,在综合分析这些问题的基础上,才能合理设计井眼轨迹方案。本文主要基于熵权法,对大位移井井眼轨迹设计方案进行对比分析,为之后大位移井钻井技术的优化提供了参考。
in the process of continuous optimization and improvement of drilling technology,the application of extended reach drilling technology is more common.In the process of extended reach well drilling,we must pay attention to the well trajectory design in order to ensure the safety and efficiency of operation.In the process of practical operation,there are mainly problems such as difficult to clean the wellbore,poor wellbore stability and serious bending of the pipe string.On the basis of comprehensive analysis of these problems,we can reasonably design the wellbore trajectory scheme.Based on the entropy weight method,this paper compares and analyzes the design schemes of extended reach well trajectory,which provides a reference for the optimization of extended reach well drilling technology.
