摘要
南海西部涠洲油田开发到中后期,大斜度井及水平井的分层需求增多,通过钢丝作业开关滑套这种传统的分层技术无法满足要求,智能分层技术研究与应用迫在眉睫。本文调研国内外主要几种智能分层技术,分析它们工作原理及优缺点,以涠洲油田A井为例,通过对比优选出机械智能滑套分层技术并成功应用,该技术施工简单、易操作、成本低,具有良好的经济性和时效性。
As the development of the Weizhou Oilfield in the western South China Sea reaches its mid to late stage,the demand for stratification in high angle and horizontal wells has increased.Traditional stratification techniques such as wire operated switch sliding sleeves cannot meet the requirements,and the research and application of intelligent stratification technology are urgently needed.This article investigates several major intelligent layering technologies at home and abroad,analyzes their working principles and advantages and disadvantages.Taking Well A in Weizhou Oilfield as an example,the mechanical intelligent sliding sleeve layering technology is selected through comparison and successfully applied.This technology is simple to construct,easy to operate,low in cost,and has good economy and timeliness.
