SYSTEM OF COTROL OVER EXTRACTING HYDRO-CARBON RAW MATERIALS FROM MULTI-PAY FIELDS Russian patent published in 2010 - IPC E21B47/12 E21B43/12 

FIELD: oil and gas production.

SUBSTANCE: system of control of extracting hydro-carbon raw materials consists of well sub-systems united with local information-computing network. Each well sub-system consists of the first controller connected to the local information-computing network via an interface block. The first controller is coupled with an above-ground facility of control of process equipment and is tied to the second controller via the first block of communication by means of a communication channel and a transmitter-receiver. The second controller is tied with a block of sensors, with a block of actuating devices and also with the second channel of communication coupled with an output of a feeding block. An electro-mechanical gripping device including a drive and an executing mechanism of gripping is secured to a lower part of an electric centrifugal pump. A well anchor combined with an off-line module is positioned below the electro-mechanical gripping device.

EFFECT: upgraded operational characteristics of system for control of hydro-carbon raw material extraction.
