摘要

中5 - 平615 井是孤岛油田的一口调整水平井,井身剖面采用国内外罕见的上阶梯式,施工难度很大。施工中运用了调整井技术、水平井井身轨迹控制技术、FEWD 地质导向钻井技术,钻井施工安全无事故,累计钻开油层370 m ,满足了地质开发要求。本井的成功施工为该地区薄油层调整水平井的施工积累了宝贵的经验。本文介绍了该井的施工技术。

Abstract

Zhong5 - ping615 is an adjustment well in Gudao

Oilfield. For its stair - stepping profile ,the drilling operation

become very difficult . In the drilling course ,many techniques

are applied ,such as adjustment well technique ,horizontal well

trajectory controlling technique and formation evaluation

while drilling technique etc. ’so the drilling operation is safe

and no accident . The drilled oil reservoir accumulated to a

length of 370 meters , and meets the geologic and

development requirments. The paper introduces the drilling

techniques of the well.
