| 摘 要： | 自海拉尔油田实施钻井提速以来，部分井出现螺旋井壁现象，对完井电测曲线造成一定影响，影响测井解释的共151口井，比例达15.60%。螺旋井壁现象在乌东区块尤为明显，仅乌东区块发生明显螺旋井达到36口，占乌东区块全部钻井的28.8%。从地质、工程等角度阐述了形成螺旋井的原因，并提出了解决思路与技术措施。2012年下半年在乌尔逊凹陷2口井试验螺旋井壁预防及解决方法，获得了较好的效果，未再大面积出现螺旋井壁现象。

| Abstract: | Spiral shaft lining appeared in some wells since the drilling speed improving in Hailer oilfield, log interpretation was affected in 151 wells, 15.60% of the all. This was especially obvious in Wudong block; there were 36 obvious spiral wells, 28.8% of all wells there. The paper discussed the causes of spiral well formation from the view of geology and engineering, and put forward the solution and technical measures. The tests in the second half year of 2012 showed good effects. |
