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 stability analysis were used typical longitudinal and lateral - direction stability index, while in the control analysis were estimated the control power requirements for trim, stabilization and maneuverability
