摘要
大位移井井斜大,水平段长,下入过程中摩阻大,下入悬重小,容易因为粘卡造成套管下入不到位,而漂浮下套管技术很好的解决了这一难题。本文介绍了漂浮接箍下套管的技术原理,漂浮接箍的安放位置选择,并通过实践证明了漂浮接箍下套管的可行性和有效性。
Floating casing technology can solve the misplacement of casting down-installation caused by sticking that constantly appears in the ERD(extended reach drilling)wells.This paper introduces the principle of floating casing technology and the selection of floating collar placement,and proves the feasibility and effectiveness of floating casing by practice
