官H_1中半径水平井井眼轨迹的控制

TRAJECTORY CONTROL OF GH1 HORIZOTAL WELL WITH MEDIUM-RADIUS

在进行了大量的下部钻具组合特性分析和钻头钻进规律研究的基础上，研制了定向井与水平井井眼轨迹控制分析系统（ＤＨｓ）．该分析系统在大港官Ｈ＿１井首次现场应用，取得了令人满意的结果．本文还对水平井井眼轨迹控制中可能出现的问题，提出了相应解决方案．

Based on the study of the Bottom hole assembly characteristics and bit-rockinteraction law,the analysis system of directional and horizontal well trajectorycontrol(DHS)is developed.This system is satisfactory in first application to Dagang GH1horizontal well trajectory control.Accurate theoretical analysis results play a positive role inimproving drilling technique and ensuring design level to actual well trajectory.Someexplorations are made in combining theory with practice. Meanwhile,relative methods forsolving the possible problems are presented in horizontal trajectory control.
