Experimental research on prediction of build-up rate of BHA in small-diameter hole;
小口径孔底动力螺杆钻具组合造斜率预测实验研究
The Influence factors to build-up rate using screw drill such as structure,WOB and borehole parameters in TAHE oilfield was studied,structure and formation factor was considered to be the key factors.
为精确预测塔河油田螺杆钻具造斜能力,深入分析了螺杆本身结构对钻具组合造斜率的影响规律,研究运用几何造斜率计算方法,使用合理的计算模型对螺杆钻具理论造斜率进行了计算,并与统计的塔河油田某区块螺杆钻具实钻造斜率对比,得出了不同实钻地层所对应的螺杆钻具造斜率修正系数,用于修正理论造斜率计算模型,吻合程度较为理想。
Furthermore,it gave a set of analyzing and calculating method to control the horizontal section trajectory in horizontal well through analyzing the relationship between the geometric attitude of the wellbore trajectory and the build-up rate of the tools.
在此基础上,通过对井眼轨迹几何姿态与工具造斜率的关系分析,综合水平段钻进的特点,提出了一套水平井水平井段轨迹控制分析计算方法,用于指导水平段轨迹控制的施工。
Based on the method of equilibrium curvature, built-up rate of h.
分析了不同井眼曲率和不同弯角下120mm大角度单弯螺杆钻具组合应力分布情况,最大等效应力随着曲率的增加先减小后增大,随着弯角的增大而增大;采用平衡曲率法,对大角度单弯螺杆造斜率进行了计算。
To meet the demand of higher built-up rate,single-bending screw drill tool with large angle is used during the drilling of the moderate-and short-radius horizontal well.
钻中短半径水平井,在采用弯角较大的单弯螺杆钻具以满足高造斜率的需要时,由于套管内径较小,螺杆钻具钻头处位移比较大,螺杆钻具能否顺利通过直井段是钻中短半径水平井面临的一个重要问题。
