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。
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 a11. 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 engi- neering, and put forward the solution and technical measures. The tests in the second half year of 2012 showed good effects.
