摘要

目前侧钻小井眼井油层套管内径小( 76 mm ), 相应的修井工艺技术及井下工具

极其贫乏。针对小井眼侧钻井的特点, 自主开发研制或引进了配套的井下工具, 通过现场试验

与研究, 解决了一系列技术难点, 形成一套实用有效的侧钻小井眼修井工艺技术。该工艺技术

经多次现场应用, 取得了令人满意的效果。

Abstract

A t present, the ins ide diam ete r of casing for side- tracked
slim hole is sm a ll ( 􀀁 76mm ), but it lacks the appropr ia te
w orkover techn ique and the m atched downho le too ls. Based
on fea tures o f side-tracked slim ho le, the m a tched downho le
too ls have been researched and developed independently o r
introduced. Through the field test, app lication and research,
a se t o f practical and effective w orkover techn iques fo r the
side-tracked slim ho le hav e been form ed, which so lved a
ser ies o f techn ica l problem s in the wo rkove r technique for the
side-tracked slim ho le. The techn ique has achieved satisfied
resu lts in m any fie ld applica tions.
