Abstract

The invention provides a rheological property monitoring device for drilling fluid. The device comprises a tank body arranged in a diversion trench, a detection device, a driving device, a moving body, a rotary viscometer and a data processing device; the detection device is used for sending a first signal to the driving device and the rotary viscometer when detecting that a stirring part of the rotary viscometer is inserted into the drilling fluid in the tank body; the driving device is used for driving the moving body to move in the vertical direction and stopping driving the moving body tomove if the first signal is received when the moving body is driven to move; and the rotary viscometer is used for driving the stirring part to rotate if the first signal is received, and acquiring the rotating speed information of the stirring part. The device realizes automatic implementation of the monitoring of drilling fluid rheological properties, and compared with manual monitoring, the device can prevent testers from entering a monitoring place, so that the safety of the testers is effectively guaranteed.

Description

Technical field [0001] The invention relates to the field of petroleum exploitation, and in particular to a rheological monitoring device of drilling fluid. Background technique [0002] Drilling fluid is a general term for various circulating fluids that meet the needs of drilling work with its multiple functions during drilling. During the drilling process, the rheology of the drilling fluid will change. If the rheology is not good, it may cause the well wall to collapse, and the drilling and suction gas intrusion may cause safety hazards. [0003] In the existing related technology, the rheology can be monitored manually by measurement personnel, and the drilling fluid can be sampled, analyzed, and evaluated manually. [0004] However, the hydrogen sulfide contained in the drilled formation, a large amount of gas intrusion, extreme weather and other reasons may cause danger to the health of the surveyor, even the life zone, and the safety is not good. Summary of the invention [...
