Experimental study on a six-speed online measurement system for drilling fluid rheology
摘要
Abstract
To address the issues of poor real-time performance and insufficient accuracy in traditional manual measurement of drilling fluid rheological parameters,this study developed a six-speed online drilling fluid measurement system.By deriving the shear rate based on the concentric cylinder flow model,parameter solutions were achieved by incorporating the Bingham model,power-law model,and Herschel-Bulkley rheological model.The end effect was analyzed through CFD numerical simulation,and a corresponding dynamic correction method was proposed.An experimental platform was established to compare the measurement results of the online module with those of a standard Fann 35 viscometer.The test results show that the system exhibits high consistency with the benchtop viscometer,with an average deviation of less than 5%between the readings.The fitting error of the HB model is below 2%,significantly outperforming the Bingham model.Temperature reduction markedly increases plastic viscosity and yield stress,enabling data standardization through temperature compensation.The system responds to step changes in rotational speed within approximately 2 s,demonstrating excellent dynamic performance.This system enables real-time,continuous,and high-precision measurement of rheological parameters,providing effective technical support for intelligent monitoring of drilling fluid performance and safe,efficient drilling operations.关键词
