Flow Filed Simulation Analysis of Nearly Balanced Drilling Mechanism

Abstract:

In order to eliminate the negative effect of pressure effect-continuation effect and not to affect drilling liquid washing the bottom of hole in nearly balanced drilling. This paper mainly presents the structure design method based on the nearly balanced drilling device theory, makes use of numerical simulation technology to analyze accurately the flow filed of drilling liquid in the certain working condition and uses k-ε model to simulation this problem. Simulation results show the pressure field and velocity field is consistent with the design requirements.
