The pipeline friction measurement device is used to study the shear rate of fluid flow in the laboratory test pipeline after adding a certain reducing fluid, and to conduct experiments in the same way as the shear rate of liquid flow in the pipeline during on-site construction. Thus, it is used to simulate the flow state of liquid during on-site construction, determine pipeline friction, and evaluate the quality of drag reducing agents.

To evaluate the performance of drag reducing fluids, further understand the variation laws of friction resistance at different drag reducing fluids, different displacements, and different well depths, and provide a basis for selecting and optimizing drag reducing fluids.
