RECOVERY METHOD OF GAS CONDENSATE Russian patent published in 2009 - IPC E21B43/00 E21B33/03 

FIELD: mining.

SUBSTANCE: invention relates to mining and can be used at development of gas-condensate field with usage of remote, automatic and unmanaged mode of sluices of well. According to method at deposit there are drilled and equipped producing welt clusters. In it there are installed production strings, introduced in them columns of tubing pipes, outfitted by subterranean production equipment, including pilot-controlled subterranean valve-clipper of gas, and control head, including production tree with sluices, including, not less than one side and one over-basic slide valves. It is mounted on trail throttle valve and it is installed supervisory control devices of system of emergency shutdown of well. These systems includes at least control valve of low and high pressure and filament. It is connected at least part of welt clusters of deposit to station and block of control stations for sluice of production tree and subterranean valve-clipper, which contains pump-and-accumulator station with force hydropneumatic accumulator and not less than one, tendering well control block with field lines and functional management of actuating mechanism for sluices. To it is bind logical control line, outfitted not less than three times duplicated starting mechanisms, including two from which operate from pulse, fed for closure of well at appearance of fire danger, or supercritical little or high pressure in trail. It is developed system of shutting-in of well in logical succession of fluid cutoff: "side valve - over-basic valve- subterranean valve-clipper", operating through the system of slowdown of command passing for closing. This system includes tandem consisting of controlling hydropneumatic accumulator and throttle in logical control line at sections of interaction with field lines of functional management for actuating mechanisms of over-basic valve and subterranean valve-clipper.

EFFECT: reliability growth and trouble-free operation of deposit, cost saving of products extraction, simplification of management of processes ensured by automated management of well's sluices.
