The build rate of the tools is a key point in trajectory control and prediction of horizontal well, which is based on the mechanical analysis and geometry analysis of tools. But if the tools have initial bending, the application of “beam-column theory” is limited. With a method of equivalent loading, this problem can be solved. Through the analysis of tools, the side force of bit can be calculated, and then a method, named “method of modified three-point fix Round” is used to determine the build rate of tools at the basis of VB program.
