The compounding slide steering drilling mode of this technology was studied and the method calculating the steering force of the slide steering assemblies was brought forward in this paper. The influence of the main parameters was also studied. The results show that by designing the structure of the slide-steering BHA carefully, an appropriate steering force can be gained. For the safety of drilling practice and a good control of well trajectory, the bending angle of down hole motor should be selected carefully.
