摘要

介绍了长裸眼中斜度定向井的钻井液体系及处理方案,以及润滑防卡、井眼净化和井壁稳定等3个关键技术问题的解决方法。列举了4口井的应用情况及钻井液性能。实践证明,所选择的钻井液工艺技术较好地满足了钻深3623m、井斜49°、井底水平位移1229m、裸眼井段长达3224.5 m、裸眼斜井段长达2292 m的定向井对钻井液的要求。

Abstract

This paper describes the drilling fluid systems and maintenance programs for medium inclined directional well with long open hole, and it focuses on drilling fluid lubricity and anti-sticking property, hole cleaning capability and wellbore stability control. Drilling fluid performance in four wells are evaluated. The drilling fluid technology has been successfully used in a directional well with total measurement depth (TMD) of 3625m, hole deviation of 49°, horizontal displacement of 1229m, and 3224.5m open hole, in which 2292m is in the inclined section.
