英文
crooked well-
Along with the progress of drilling technology, many new types of bha such as steering motor assembly, dropping assembly with eccentric bend sub, dropping assembly with flexible connection are developed based on common building, dropping and holding assemblies. for using these bha, a new mathematical model is put forward for 3d static analysis of these types of bha under small deflection. and its weighted residual solution is given. the mathematical model includes ( 1 ) differential equations ; ( 2 ) boundary conditions at drill bit, stabilizer, bend angle, diameter change, tangential point and borehole wall ; ( 3 ) lateral forces and deflection angles of bit. the software based upon this method runs well
為了更好地應用各種新鉆具，建立了適用於對普通下部鉆具、導向鉆具、帶偏心彎接頭和柔性接頭的下部鉆具進行三維小撓度靜力學分析的數學模型，包括（ 1 ）微分方程； （ 2 ）鉆頭、穩定器、彎角、變截面、切點和井壁的邊界條件； （ 3 ）鉆頭的側向力和鉆頭轉角.給出了該模型的加權余量解.用該方法編寫的軟體應用效果良好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。
