DATA TRANSFER SYSTEM FOR MONITORING OF HYDROCARBON PRODUCTION PROCESS Russian patent published in 2013 - IPC E21B47/14 

FIELD: oil and gas industry.

SUBSTANCE: system includes a ground part in the form of a ground-mounted unit of a telemetric system of an electric-centrifugal pump installation and a well part including signal transfer medium of a combined communication channel, a submersible unit of the telemetric system of the electric centrifugal pump installation, an interface unit, receiving and independent transmitting and control modules and a measuring loop. The latter includes several measuring probes arranged one after another and parallel connected via a cable communication line connected to the independent transmitting and control module. The receiving module together with the interface unit and the submersible unit of the telemetric system is attached to the base of the submersible electric motor of the electric centrifugal pump installation. Information from the measuring loop is received with the independent module. Communication between independent and receiving modules is performed by means of a wireless acoustic channel. Then, measuring information is transmitted through the submersible unit via the combined communication channel to the ground-mounted unit of the telemetric system.

EFFECT: improving reliability of the data transfer system owing to preventing cable damage situations of the measuring loop and improving the efficiency of the monitoring process owing to decreasing complexity of lowering and lifting operations at erection and removal and excluding cases of tubing seizure with a geophysical cable.
