HYDROCARBON MATERIAL EXTRACTION CONTROL SYSTEM Russian patent published in 2009 - IPC E21B47/12 E21B43/12 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to coal industry, and is meant for controlling hydrocarbon material extraction. System includes several groups of wells each of which consists of well subsystems integrated by means of local information computer network which, by means of a link, is connected to the extraction control device unit through a heterogeneous information network. Each well subsystem consists of a parameter control module which is connected through the first communication link to the ground control unit of process modes, which in its turn is connected to local information computer network. Additionally, in the well subsystem there is the second communication link and information control unit which is connected to parameter control module and through the second communication link - to control unit of process modes, and whereto there connected is electric power supply device. Each well subsystem represents a distributed structure consisting of the first, second and third levels. The first level in bottom-hole zone consists of several downhole surveying devices, each of which includes the first controller, the inputs of which are connected to the first thermodynamic parameter gage unit and to the first actuator unit, and which is connected through the first link unit to the second level of the well subsystem, which is located in the area of lift string shoe. System parameter control module is connected through the first communication link to the process equipment control unit which is included in the third subsystem level and located on the surface.

EFFECT: improving control quality owing to output optimisation and control action realisation based on continuous monitoring of status of productive formation and wells.
