摘要
随着油田4吋套管井数量的增多,4吋套井如何实现高效打捞已是提高作业施工效率的重要影响因素。针对4吋套内打捞复杂的问题,自主设计了高效4吋套打捞工艺。该工艺采用高效套铣工艺,由原来起下4趟钻打捞1根油管改进为起下3趟钻打捞出1根油管,很大程度提高了打捞效率。
With the number increasing of4-inch casing used in oil wells in the oilfield,the way to realize high efficient fishingby4-inch casing wells has become an important factor to improve the operation efficiency.In light of the complex problems in4-inchcasing fishing,4-inch casing fishing technology is designed independently.This tecgnology applies high efficiency sheathed millingunit with three-times drilling for1oil piple fishing out changed from four-times drilling for1oil pipe fishing out,which improvesthe fishing efficiency greatly in a large extent.
