WELL CEMENTATION SYSTEM "Kostromich" Russian patent published in 2004 - IPC

FIELD: oil and gas extracting industry. SUBSTANCE: system has a mounting base, on which water supplying means, transmission connected to two plunger pumps, manifold, means for exhaust, draining and heating connected to manifold, commingler and measuring tank, and operator's cab with management and control system are located. System also includes equalizing station, computerized station connected to measuring means, sensors and dial devices located on the manifold, measuring tank, operator's cab and equalizing station. Behind the operator's cab on said mounting base two self-contained powered devices connected to two parallel plunger pumps with two quick-assembling plunger couples with a packet of sealing rings in a separate housing are located. Plunger pumps are connected to suction, force-pump and overflow lines forming a complex manifold, which has instrumental section and unified quick-assembling connection means for engaging plunger pumps. Supporting pump placed below measuring tank is mounted in suction line. Below operator's cab hydraulic means for driving water supplying and supporting pumps and controlling valves and gates of complex manifold is located. Heated operator's cab with means for management and control is located in the center of mounting base. Exhaust means for two powered devices, purging, draining and heating by means of base drive are made self-contained and connected to hydraulic part of plunger pumps, to water supplying pump and complex manifold. EFFECT: replaces a set of machines up to 12 units depending on wells and force- pump parameters with a specialized system requiring minimal maintenance. 5 cl, 3 dwg
