Abstract
A partial pressure tool for real-time measurement and adjustment of pressure and viscosity and a measurement method thereof. The partial pressure tool includes an outer cylinder and adjustable annular throttling grooves, and the adjustable annular throttling grooves are split-type grooves vertically and successively installed on an inner wall of the outer cylinder at equal intervals. Four single throttling grooves are adjacent to each other and arranged concentrically on a circumferential surface. A viscometer is installed on a surface of an arc-shaped inner plate in a tail-end adjustable annular throttling groove. The viscometer is connected to an induction board through a transmission line. The arc-shaped inner plate in the tail-end adjustable annular throttling groove is provided with a pressure sensor and a torque sensor, and the pressure sensor and the torque sensor both are connected to the induction board. The induction board is connected to a DSP control module.
