应用CFD软件对涡轮钻具组的内流场进行了分析研究，重点讨论了模拟压降和扭矩。
The internal flow field of multi-turbine is studied by CFD software, and the simulated pressure drops and torques are discussed in this paper.
同时以一组双稳定器钻具组合为例，分析钻具节点的位移变化图、弯矩图和应力分布图可得出钻具上的受力变形情况。
Moreover, taking the BHA with two stabilizers for example, based on analyzing the displacement, bending moment and stress on the nodes of BHA, the force and deformation of BHA are obtained.
