TELEMETRIC INFORMATION TRANSMISSION SYSTEM AND SUBMERGED MODULE Russian patent published in 2019 - IPC E21B47/12 

FIELD: oil industry.

SUBSTANCE: proposed technical solutions relate to the oil industry, namely, to the systems and devices for the transmission of information and electrical energy from submersible actuators during the operation of wells for the production of fluid. Telemetry information transmission system (System) contains the ground module (GM) and the submersible module (SM), which are connected through the motor power supply circuit, it is made with the possibility of supplying the required supply voltage to all elements that need power. In this case, the SM contains the device for power supply and transmission of the coded telemetric information (CTI), the SM (SMD) control device for the collection and transmission of information, which processes data from at least one measuring device (MD). MP additionally contains the high voltage power supply device (PSD), the power selection device (PS) and the alternative information transmission device (AITD), which ensure the functioning of the MP and the transmission of telemetry information in case of short-circuit on the communication line. GM contains the control unit of the ground module (GMD) for processing the incoming information and exchange with the consumer and between the SM and GM, the main receiver of the coded telemetry information (PDR), as well as a power supply unit for the GM, an insulation measurement unit (MU) and an alternative receiver of coded telemetry information (ARCTI), the input of which is connected to the SM input, which is connected to the windings of the three-phase transformer of the power supply circuit of the motor to ensure the reception of telemetry information from the AITD, when reception through the multifunctional input/output of the SM is impossible or unreliable, and the output is connected to the SMD or SM output for data transfer to the consumer. GM can contain an independent power source (IPS), the input/output of the GMD can be connected to the input/output of the PS to control its operation, and the power supply device may contain the overvoltage protection (OP) device, the input/output of which is connected to the power supply input/output, and the output – to the power supply output through the main power supply device (MP), while the output of the main information transmission device (MITD).

EFFECT: telemetry information transmission system (System) contains modules designed to supply the required supply voltage to all elements that need power.
