裸眼侧钻技术在川马页1井的应用实践
Application of open hole sidetracking technology in Well Chuanmaye 1
摘要
Abstract
Well Chuanmaye 1 is a shale gas parameter well deployed in Mabian,Sichuan.When drilling to 3437.58m,there were drilling complexs and sealed with cement after the first stage of treatment was unsuccessful.This article proposes a three hole open hole section sidetracking technology scheme for the complex situation of Well Chuanmaye 1.Based on the analysis of the factors affecting the sidetracking force near the drill bit position,combined with the actual situation,the sidetracking point,sidetracking method,and sidetracking tool combination were optimized,and the sidetracking technical measures were determined.After two rounds of sidetracking construction,the construction difficulties such as lack of adjacent well data,large sidetracking depth,complex formation prone to collapse,high temperature and formation strength in the sidetracking section,small inclination of the original wellbore,and limited sidetracking direction were overcome.Finally,a new wellbore was drilled and reached the predetermined depth.Provided reference for subsequent drilling construction and complex treatment in the region.关键词
