TELEMETRY SYSTEM OF OPERATED WELL Russian patent published in 2015 - IPC E21B47/00 

FIELD: mining.

SUBSTANCE: proposed system comprises surface data receiving and processing unit connected in supply circuit electrical cable - downhole motor (DHM) with downhole telemetry unit (TU) port. Said TU has a through lengthwise hole to control and to transmit to surface data receiving and processing TU, data covering the parameters of top and bottom beds. Note here that TU port is connected via serial data collection and transmission unit, communication interface and power supply with its extra port whereto connected is well bottom bed parameters metering unit (MU) via sealed connector. Said extra port is intended for transmission of requested date from MU to TU. MU and TU are interconnected via sealed connector fitted in TU case cut-out Said telemetry serial data collection and transmission unit can generate packages of data on top and bottom bed transducer parameters from MU and convert said data for transmission to surface data receiving and processing unit via downhole motor supply cable for said data to be recognized for transmission to user.

EFFECT: better manufacturability of system assembly and higher reliability of operation.
