PUMP-COMPRESSOR BOOSTER PLANT Russian patent published in 2005 - IPC

FIELD: oil producing industry.

SUBSTANCE: proposed plant is designed for use at production of hydrocarbons for delivering process liquids, gases and multiple-phase media and at secondary and tertiary methods of increasing of oil recovery of oil bearing beds, and completion of oil and gas wells, etc. Proposed plant includes positive displacement pump, for instance, plunger pump, consisting of one or several sections with compression chamber, drive, manifold including feed pump communicating with service liquid tank, pipeline to deliver gas into booster chambers and exhaust piping communicating with compression chambers and with consumer. Proposed plant contains liquid separating unit installed in exhaust piping between compression chambers of pump and consumer. Said unit consists of high-pressure separator, restrictor and device to discharge liquid connected to each other and installed in tandem. Device to discharge liquid communicates with gas supply line to booster chambers and, through separate adjustable restrictor, with service liquid tank. High-pressure separator of said unit is three-step, and restrictor is multistep. Liquid discharge device is made in form of hollow cylinder with free piston and reel-type discharge spool locked in open and closed positions and interacting with free piston.

EFFECT: enlarged operating capabilities.
