Abstract


A set of on-line test equipment for drilling fluid rheological parameters is developed, which can realize real-time on-line monitoring. Design method: first of all let the drilling fluid to flow through the same shape and dimension of the section, in turn, change, will produce different velocity of different section, between all the pipe sections using pressure sensor real-time acquisition of differential pressure value, and the differential pressure and flow rate signals to the data acquisition system for transformation, such as display and processing, and then according to the rheology model to calculate the rheological parameters of drilling fluid to be measured. The final measurement results will be compared with the results of rotary viscometer measurement, shows the practicability and feasibility of the device have zero since the calibration function, measuring range is 5-150 mpa’s, measurement accuracy can satisfy the requirement of 5%.

Keywords
