DEVICE FOR REMOTE CONTROL OF MUD PARAMETERS IN MUD DITCH Russian patent published in 2014 - IPC E21B21/01 E21B44/00 

FIELD: oil and gas industry.

SUBSTANCE: device contains at least a temperature sensor, level gages and a mud flowmeter and a density gage that includes a gamma radiation source and a detector block as well as an electronic signal processing unit and a computer. The temperature sensor, level gages and the mud flowmeter and the gamma radiation source are mounted together in a space-saving way on the common load-carrying platform made as a quick-disconnecting hatch cover in the upper part of the mud ditch. Inside of the latter there is a suspended acoustically transparent container rigidly coupled to the platform and divided into two cavities; in one cavity there is the temperature sensor while in the other one there is a velocity metre made as an electroacoustic transducer interacting through the contact surface with the container wall and faced by a transducing surface towards the mud ditch surface. The gamma-radiation source is placed on the outer lower surface of the container.

EFFECT: high accuracy of the monitored parameters, simplicity, small size and mobility of the design, handling safety, reduction of time period for assembly and disassembly.
