GEOSTEERING COMPLEX COMBINED WITH A NEAR-BIT MODULE FOR MEASURING FORCE PARAMETERS Russian patent published in 2023 - IPC E21B47/12 

FIELD: oil and gas.

SUBSTANCE: complex contains a processing and visualization unit in the form of a computer connected to a monitor, a downhole telemetry system located in close proximity to the downhole motor, and a tool for inclinometric measurements. The near-bit module for measuring force parameters is located above the bit and is equipped with a sensor to start measurements. The body of the bit module is formed by the upper and lower subs, a strain gauge transducer in the lower part of the lower sub with resistance strain gauges glued to its inner surface. The internal cavity of the strain gauge transducer is filled with an inert liquid and the channel communicates with the pressure compensator. Inside the case, in a container on shock absorbers, a power supply unit and an electronic unit with a transmitting module connected by a wireless channel to a telemetry system transmitting the measured power parameters to the surface along with the results of inclinometric measurements are installed.

EFFECT: prevention of deviation of the wellbore from the specified direction.
