摘要: 提出了水平井和侧钻水平井筛管顶部注水泥技术,改变了常规的水平井筛管完井工艺中筛管顶部套管(尾管)不注水泥、外部环空彼此窜通的状况,为射孔开发筛管顶部过渡段油层、可靠密封过渡段水层提供了条件;研究了筛管-管外封隔器-盲板-分级箍和管外封隔器-盲板-分级箍悬挂器两套工艺,分别实现了水平井和侧钻水平井的筛管顶部注水泥固井,对20口井进行了现场试验,取得了较好的效果.

Abstract: The technology of top screen pipe cementing of casing and liner in the horizontal well and sidetracking horizontal well was presented.This technology is different from the general method without cementing at the top of screen pipe in casing and liner.It can isolate the liner from the external casing and formation,and provide the possibility of perforating oil layer in the transition segment.Two sets of crafts in casing were made.One is the combination of the screen pipe,external casing packer,drillable plug,stage cementing collar for horizontal well,and the other is the combination of the external casing packer,drillable plug,stage cementing collar,drilling liner hanger for sidetracking horizontal well.The successive field test of twenty wells has been achieved.

Key words: horizontal well, sidetracking horizontal well, screen pipe completion technique, external casing packer, cementing technique
