The technical solution of the utility model is achieved in that a kind of shale gas well gas testing gas producing device, comprises christmas tree, flow line, gas testing pipeline and relief line,
Described flow line and christmas tree removably connect;
Described gas testing pipeline is in turn connected to form by heat interchanger and gas testing eliminator, choke valve group is provided with between described heat interchanger and gas testing eliminator, the outlet line of described gas testing eliminator is connected with manual platform gate valve and blow-down pipe in turn, described blow-down pipe is provided with pressure regulator valve, and the blowdown pipeline of described gas testing eliminator is connected with manual platform gate valve;
Described relief line is connected with christmas tree, and described relief line is provided with control valve group.
Further, the outlet line of described gas testing eliminator is also provided with flow meter, and described flow meter is located between manual flat valve and pressure regulator valve.
Further, described flow meter adopts valve-type orifice-plate flow meter.
Further, be provided with tube connector between the outlet line of described flow line and gas testing eliminator, described tube connector one end is located between outlet line flow meter and pressure regulator valve, and the other end is connected with flow line.
The beneficial effects of the utility model are: a kind of shale gas well gas testing gas producing device of the present utility model compared with prior art, obtains following technique effect:
(1) reduce natural gas vent amount, energy conservation, reduce environment pollution.Connect gas testing flow process before gas testing, flow line is connected to gas production wellhead simultaneously, but is not communicated with christmas tree, and test line connects branch line to flow line, will test natural gas access gas production flow process, and reduce natural gas vent time and emptying amount.
(2) flow process safety is strengthened.Gas testing pipeline increases pressure regulator valve, and pressure regulator valve release pressure arranges 5.5MPa, controls gas testing process pressure in 5.5MPa, ensures gas testing flow process safety.By the valve-type orifice-plate flow meter in gas testing flow process, simplify gas production computational methods and improve measuring accuracy.
(3) remarkable in economical benefits.Shorten the natural gas vent time, decrease natural gas vent amount, thus gas production improves, and then increase economic efficiency.
