Two, background technique: at present, the LNG Liquefied natural gas air supply system that drilling well is used adopts the tooling at liquefied natural gas vaporization station, then seems obviously not enough being applied to drilling well special operation industry.Deficiency show as following some: 1, the tooling at liquefied natural gas vaporization station; As fixed vaporizing station, on the making volume, only consider that disposable resettlement puts in place, therefore the volume of vaporization sled is bigger; Be not suitable for the characteristics of drilling team's mobile operational process, be unfavorable for resettlement; 2, the LNG Liquefied natural gas air supply system gas consumption of civilian and general industry boiler, generating usefulness is more stable; And the load variations of the natural gas engine of drillng operation is frequent; Impact load is big; The maximum required natural gas amount of instantaneous load far surpasses the designed capacity of vaporization sled, and under this kind operating mode, gas discharge can not satisfy the instantaneous load needs and cause engine speed unstable or flame-out; 3, fixed vaporizing station can conveniently connect the external high pressure power supply, sets up special-purpose automatically controlled control machine room and electric heating system, and drillng operation is because operation in the open air, and Special Automatic automatically controlled control machine room and electric heating system make cost and installation difficulty increase undoubtedly; 4, the boil-off gas that produces in the process of unloading of fixed liquefied natural gas vaporization station storage tank, can through through emptying or directly transmission pipeline network reduce pressure, and, caused the waste and and the high-risk well site unsafe factor of rock gas in the drilling well site emptying.
Three, summary of the invention: the purpose of the utility model provides the drillng operation convenient removal; Safe and reliable, that energy consumption is low a kind of movable liquefied natural gas air feeder that is used for drilling well site, the tooling that it has overcome the liquefied natural gas vaporization station is applied to the defective of drillng operation.The purpose of the utility model is achieved in that it is to be revealed controller, rock gas import, gas outlet, end socket, heat exchange gas pipe, water jacket, intake pipe valve and outlet pipe valve and be formed by connecting natural gas storage tanks, Decompression valves, stop valve, fluid stop valve, Emergeny Cutoff Valves, the first preheating section air temperature type vaporizer, first cryogenic globe valve, the empty warm vaporizer of bringing-up section, the second preheating section air temperature type vaporizer, second cryogenic globe valve, instrument air valve, pressure regulator valve group, knock out drum, pressure controller, temperature controller, combustion gas; The outlet of liquid container is connected with the inlet of vaporization sled; Gas phase top at liquid container; Stop valve, Decompression valves and pipeline are connected in series, and pipeline outlet is connected with pipeline between liquid container Emergeny Cutoff Valves, the stop valve.
First cryogenic globe valve, second cryogenic globe valve, the first preheating section air temperature type vaporizer, the second preheating section air temperature type vaporizer are connected in parallel; The empty warm vaporizer of bringing-up section is connected with the outlet of the first preheating section air temperature type vaporizer, the second preheating section air temperature type vaporizer; The outlet of the empty warm vaporizer of bringing-up section connects the pressure regulator valve group; On the pipeline between empty warm vaporizer of bringing-up section and the pressure regulator valve group; An instrument air valve is arranged, and the outlet of instrument air valve connects the import of the Emergeny Cutoff Valves of liquid container through soft pipeline; The outlet of pressure regulator valve group is connected with the import of knock out drum, and the outlet of knock out drum is connected through the soft pipeline pipeline with the natural gas engine import.
The valve upper end, top that temperature transducer is installed on the pipeline between empty warm vaporizer of bringing-up section and the pressure regulator valve group, pressure controller is installed in knock out drum, the gas leakage controller is installed in an end of storage device, and the circuit of three controllers is connected in series; Storage battery is connected with high-voltage power; The signal source outlet of three sensors is connected with the inlet line of intelligent controller, and the egress line of intelligent controller and monitoring alarm display unit and Emergeny Cutoff Valves are connected in parallel.
Promising rock gas import on water cycle heating equipment end socket in front has heating back gas outlet on the end socket of back; The intake pipe valve is fixed on the bottom of end socket one end, and is connected with the motor water outlet, and the outlet pipe valve is fixed on the top of end socket one end, and is connected with the water intake of motor; The heat exchange gas pipe is welded in the end socket; The tubular space that circularizes of water jacket and heat exchange gas, the intake pipe valve is fixed on the bottom of end socket one end, and the outlet pipe valve is fixed on the top of end socket one end.
Workflow is: LNG Liquefied natural gas with liquid state flow into vaporizer preheating section or, two vaporizers can be switched use in turn.After preheating, the cryogenic gas that exists with gas phase, in the further heat exchange of the bringing-up section of vaporizer, gas gets into the pressure regulator valve group with the temperature that is lower than environment 5-10 ℃.The pressure regulator valve group is through after the pressure regulation, and the knock out drum that the gas warp is 0.5 cube gets into water-cycle heating unit feeding motor and uses.When liquid container pressure raises, reach the setting pressure of pressure releaser Decompression valves, boil-off gas is through by stop valve, Decompression valves and pipeline outlet, makes the LNG of gaseous state be discharged into the outlet of storage tank, gets into vaporizing unit.
The meaning of the utility model is: make the drillng operation convenient removal, and safe and reliable, energy consumption is lower.It is big on the skid volume that it has mainly solved same device, is unfavorable for the problem of the resettlement of drilling team; Guaranteed drilling well natural gas engine air feed continuous and stable in load variations and assault load; Foundation meets well site actual with safe automatical control system, heating system; When the boil-off gas that liquid container produced raises jar internal pressure, can be discharged into vaporization to pressure automatically and pry into mouth, avoided having increased the well site Security because emptying causes the waste of combustion gas.
