Mechanism Analysis on Powerful Chip and Drag Reduction of the Polymer Drilling Fluid

Based on power law fluid flow parameters in pipelines from analytical deduce, the mechanism of the commonly used polymer drilling fluid can be analyzed. The calculation results will be compared with ordinary Newtonian fluid‘s calculation results and be verified by the indoor experiment data and application drilling data. Through the MATLAB, the relationship of Power- law fluid between pressure drop (dp / dl) and flow (Q) and the velocity distribution can be calculated. The results show that analysis of polymer drilling fluid with Power-law fluid to strong chip and mechanism of drag reduction is more in line with the actual situation and it can deeply reveal that polymer drilling fluid has superior performance of powerful chip removal and reduce the flow resistance.
