Basing on former researcher findings, simplified and deduced the formulas of formationdeflectingforce and azimuth force of transverse isotropy formation under the condition of the anisotropy bit.
在前人的研究基础上，化简、推导出了各向异性钻头条件下的横观各向同性地层造斜力和方位力公式。

The formation natural deflecting law and force are the basic geological foundation for the well trajectory control in directional wells and deflecting-protection in vertical wells.
