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