ABOVE-BIT MODULE Russian patent published in 2024 - IPC E21B47/12 

FIELD: field geophysics.

SUBSTANCE: invention is intended for measurement of geophysical and process parameters during drilling directly near the bit. Disclosed is above-bit module comprising a housing with a central flushing hole and sealed compartments, in one of which there is a power battery inside, and in the other functionally complete unified modules, each of which is made with possibility to measure and record in memory its parameter of physical quantity and includes electronic board, which in turn consists of a physical quantity sensor, an analogue-to-digital converter, a microcontroller with a memory, a communication interface circuit and a power supply circuit. At that, input of physical quantity sensor is connected to analogue-to-digital converter, output of which is connected to the input of the microcontroller with memory, the output of which is connected to the input of the communication interface circuit, and the power supply circuit is connected to the battery by its input, and outputs to inputs of physical quantity sensor, analogue-to-digital converter and communication interface circuit respectively. Each of unified modules is made with possibility of its programming, both as a slave module and as a master module with transfer of slave modules into a low power consumption mode.

EFFECT: reduced power consumption when using the above-bit module as intended.
