Improved method evaluates deflection performance of bent housing motors

Using a downhole motor with bent housing most effectively requires determination of its deflecting performance and designing the bottom hole assembly according to the expected deflection rate.Drilling with steerable motors is an essential method to build angle and control well trajectory, and bent-housing motors have been popularly used in directional and horizontal drilling for many years.This article presents an improved method for calculating the deflection rate of bent housing motor assemblies. It provides mathematically precise formulas for reducing the work in processing the calculations. The equations are quite simple, but the precision in calculation is high enough for the calcula...
