Abstract
The disclosure relates to an automatic measuring system and a method thereof for drilling fluid parameters measurement. The system includes i. mud container, configured for test drilling fluid preparation and samples collection; ii. heat jacket, configured to keep the drilling fluid in the tank warm iii. heat exchanger, configured to simulate the practical conditions; iv. plunger pump, configured to pump the test drilling fluid to the flowing test device; v. flow test device, configured to simulate the flowing states of drilling fluid in the borehole annulus and drilling string, and also measure the pressure and flow rate of drilling fluid vi. control module, configured to obtain rheological parameters and the best rheological mode of the drilling fluid in the borehole annulus and drilling string based on the pressure and flow rate.
