GAS WELL PIPING Russian patent published in 2009 - IPC E21B43/00 E21B33/00 F17D1/04 

FIELD: mechanics.

SUBSTANCE: invention relates to mechanics and, particularly to service pipelines and may be used in primary production, namely for connecting wellhead equipment with gas or gas condensate gathering pipeline. Gas well piping consisting of several units includes socket for connecting to cementing mechanism, manifolds, flanges, pins and washers, valves, pipe-bends, t-piece, adapter, lugs, shutoff valve, gate valves and some valves being out of gas well piping content. The gas well piping is provided with inhibitor supply system, gas flow rate indicator and automatic controller of well production rate and well cluster operation synchronisation. All above is installed in gathering pipeline. Gas gathering pipeline is provided with two temperature measuring units implemented as two coils with their side surfaces being equipped with threaded lugs installed at both sides of gas flow rate indicator. The gas well piping may be implemented symmetrical with regard to the common gathering pipeline in well cluster.

EFFECT: operation may be organised in automated mode while ensuring optimal gas extraction from both single well and well cluster taking into account their interference and different wellhead pressure.
