The aim of this study is to research the force and influencing factors for bottomhole assembly with two stabilizers and one bend. Borehole trajectory control is one of the basic problems in drilling engineering and it is generally paid attention at home and abroad. Experts and scholars at home and abroad have done a lot of research in the drill string mechanics (especially the force and deformation analysis of BHA), interaction of bit and formation, borehole trajectory prediction method.
