| Abstract: | Three-Dimensional force and deflection analysis of Bottom Hole Assembly (BHA) were given with the method of weighted residuals and satisfactory results have been obtained. The computer program developed according to analysis results has the advantages of universal application, higher accuracy, simplicity and time saving. The program is suitable for computing various BHAs.This paper studies the effects of TOB and WOB on the bit lateral forces. |
