Design of an Oilfield Drilling Fluid Detection System Based on a Six-Speed Rotational Viscometer

Drilling fluid, as a critical element of drilling engineering, requires accurate performance detection to ensure drilling safety and efficiency. Traditional detection technologies exhibit limitations such as insufficient accuracy and complex operations when addressing complex downhole environments. To enhance the efficiency and precision of oilfield drilling fluid detection, this study designs a detection system based on a six-speed rotational viscometer. The system employs a six-speed rotational viscometer as the core measurement device, integrated with sensors and data acquisition cards, enabling rapid and accurate measurement of drilling fluid rheological properties. Performance testing reveals measurement errors ranging from 0.07% to 0.5%, demonstrating excellent precision, stability, and repeatability. The results confirm that this system effectively meets practical requirements for oilfield drilling fluid detection and provides reliable technical support for drilling operations.
