摘要
Abstract
The continue production of oil and water wells is well settled by slimhole sidetracking technology, the recovery efficiency improvement with lowr cost and restoration of the “dead wells” are realized.Wen 75X1 well is a sidetracked slimhole located at Wen75 fault block of Shigezhuang structural belt of Wen'an slope, its terminal depth is 3376m with incli-nation of 34.64 degrees and openhole segment of 1164m.?95.3mm small liner was put down for cementing, there were unfavourable conditions of small annular clearance and long cementing segment and it was difficult to keep casing in center position and ensure casing running down to the bottom.By adopting effective drifting methods, centralizer placing, elastic low density high strength cement slurry system and other cementing technologies, the quality detection results are 100%and 92%for cementing qualification rate and high quality rate respectively.关键词
