摘要: 中原油田针对大斜度双靶定向井井斜角大、斜井段长、目标多、井眼弯曲严重、井斜角与方位角控制困难、井眼易坍塌和易遇阻卡等特点进行了科研攻关,通过九口井的现场施工,在大斜度双靶定向井的井身轨迹控制、钻井防卡、电测易遇阻卡、提高钻速等方面取得了较大进展,获得了宝贵经验。

关键词: 双靶定向井, 轨迹控制, 防卡, 电测, 钻速

Abstract: Aimed at the problems of high angle dual-target directional well, such as large slant angle, long slant section, multitarget, severe deviation, sticking and sloughing, a study was conducted in Central China Oilfield. 9 high angle and multitarget wells were drilled, and a progress in track control, stickingrevention and increasing penetration rate, is achieved.

Key words: Large Slant Angle, Directional Well, Track Control, Sticking -Preventing, Logging Penetration Rate
