彎鉆桿
英文
bend drill pipe-
In the structure of downhole assembly for steering well drilling, the selection of tool stabilizer, upper stabilizer and calculated outside diameters, the selection of screw bending angle have influence on the side force of azimuthal increase and decrease, it can be used for evaluating the deflecting characters of steering drilling, analyzing and designing the steering downhole assembly
摘要在導向鉆井鉆具組合結構中，本體穩定器、上穩定器的選用與計算外徑，以及螺桿彎角的選用，對用全力增、減方位時的側向力有影響，可用來評價導向鉆井鉆具造料特性，分析和設計導向鉆具組合。Field application result shows that for eccentric screw stabilizer, there exist errors of calculated outside diameters and measured diameters, the upper stabilizer has severe influence on side force of drilling bits, and it can be optimally designed, while the bending angle of screw also has severe influence on bit side force, and it should be rationally used
現場使用結果表明，螺桿本體穩定器採用偏心式時計算外徑與丈量直徑存在偏差；上穩定器對鉆頭側向力具有較大的影響，可以優化設計；螺桿彎角對鉆頭側向力影響較大，需合理使用。Utilize energy method to research crook problem of drilling rod under pressure and act on together, having studied the crooked influence to the drilling rod of torsion emphatically, the theory analyses found that axial load, hole vertex angle and torque are important factors of influence drilling rod crook
利用能量方法研究了壓力和扭矩共同作用下鉆桿的彎曲問題，著重研究了扭矩對鉆桿彎曲的影響，理論分析發現，軸向載荷，鉆孔頂角和扭矩是影響鉆桿彎曲的重要因素。
