Weight on bit calculation drilling This paper introduces a practical finite element analysis (FEA) model and program, which can simulate the working behavior of drillstring during the drilling operation. Oct 12, 2021 · Keep the drilling parameter “applied weight on drilling bit” smooth once it has been optimized. When the weight component of the drill string in the direction of the hole axis is equal to the drag force-resisting downhole movement, the drill string is not able to slide downhole by its own weight and when drilling in the sliding mode the drill string will require pushing with pipe higher in the hole. Sigma Quadrant. Nov 20, 2017 · The bit should be pulled theoretically when the cost per foot is at its minimum. In his research, Al-Sudani (2017) devised a cybernetic method for monitoring the wear of drilling bits by analyzing the energy consumed by each bit. It describes how weight on bit is measured and controlled, and how optimizing weight on bit can improve drilling efficiency and rate of penetration while avoiding issues like increased wear on bits or buckling of the drill string. The conformance results of the model didn’t help to avoid BHA stuck because of hole collapse issues. This paper aims to develop a weight-on-bit control system for field implementation, using a variable-gain integrated controller and a multiple-model parameter estimator.
