摘要: 女MH-1水平井是大港油田钻成的第一口长半径水平井,也是目前国内陆地上最深的水平井.由于油顶深度及地层对井眼方位漂移不确定等因素的影响,该井井眼轨迹控制难度较大.本文将从油藏地质概况及钻井的主要特点、钻探效果、钻井技术等方面来介绍女MH-1水平井的情况,并分析讨论井眼轨迹控制等技术.

关键词: 水平井, 井眼轨迹, 方位漂移, 井斜, 井身剖面

Abstract: Nu-MH-1 horizontal well was the first large radius horizontal well drilled in Dagang oil field.Up to now,it is also the deepest horizontal well drilled on the national onshore.Because the uncertainties of the pay zone top depth and wellbore turn-off direction affected by the formation,it made controlling the wellbore trajectory very difficult.This article introduces Nu-MH-1 horizontal well from the property of the pay zone formation,the well production,the drilling programs and also analyzes and discuss the Nu-MH-1 well trajectory control techmques.

Key words: horizontal well, well trajectory, direction drift, inclination, well profile
