Abstract

The invention discloses a drilling fluid parameter measuring device and a control method thereof. The measuring device is characterized in that a Marsh funnel is suspended on a gravity sensor througha support member, and the gravity sensor measures the Marsh funnel and the weight parameter of slurry injected into the Marsh funnel and sends the weight parameter to a circuit control board; the ultrasonic sensor is arranged in the circumference of the Marsh funnel, measures slurry liquid level parameters in different periods in the Marsh funnel, and sends the measured liquid level parameters tothe circuit control board; the circuit control board controls the electromagnetic switch according to the received weight parameter and liquid level parameter of the slurry, and the electromagnetic switch controls circulation of the slurry in the Marsh funnel according to a command of the circuit control board; and the property parameters of the slurry are further calculated. Automatic timing is realized through the circuit control board, and the slurry parameters are automatically received, so that the error of manual measurement is avoided, and the working efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of drilling instruments, in particular to a drilling fluid parameter measurement device and a control method of the measurement device. Background technique [0002] Drilling fluid is a fluid used for drilling. Drilling fluid has the following functions in drilling: (1) Cleaning the bottom of the well, suspending and carrying cuttings, and keeping the wellbore clean. (2) Balance the formation pressure, stabilize the well wall, prevent well collapse, blowout and lost circulation. (3) Transfer water power to help the drill bit break the rock. (4) to transmit power for downhole power drilling tools, and (5) to cool the drill bit and drill tool. (6) Use drilling fluid for geological and gas logging. Drilling fluid drilling fluid density, drilling fluid viscosity and other conventional properties have a great impact on drilling work. The concept of drilling fluid viscosity is: drilling fluid viscosity refers ...
