STEADY STATE TUBING STRING TENSION-TORQUE PHYSICAL MODELS AND ITS APPLICATION FOR SIDE TRACKING HORIZONTAL WELL DURING WORKOVER OPERATIONS |
| |
| Abstract: | Based on the considerations of sidetracking horizontal well workover procedures, wellbore track, weight of tubing string, fluid buoyancy and friction between well wall and pipe string, pipe string steady state tension and torque physical models were built. The paper describes the model applications in the design work of first side tracking horizontal well in Daqing Oil Field. |
