The model utility content
In order to solve the problems of the technologies described above the utility model product, a kind of oil field shaft mouth output liquid temp-autocontrol oil and gas multiphase flow pressure regulator is provided, purpose is to reduce cost, reduce energy waste, reduces labor strength.
Be achieved in that oil field shaft mouth output liquid temp-autocontrol oil and gas multiphase flow pressure regulator for reaching above-mentioned purpose the utility model product, it is to be made of crude oil caliber, rock gas caliber and the oil gas mixing chamber that is connected with crude oil caliber, rock gas caliber, the oil gas output caliber that is communicated with the oil gas mixing chamber, and wherein the rock gas delivery nozzle that is provided with of the end of rock gas caliber places in the oil gas mixing chamber.
The crude oil import place of described crude oil caliber is provided with an one-way valve.
The outlet end of described rock gas caliber and rock gas delivery nozzle place respectively are provided with an one-way valve.
Described rock gas delivery nozzle links to each other with pressure regulator.
Described rock gas delivery nozzle is a multiport nozzle.
The inlet of described crude oil caliber, rock gas caliber is equipped with the heavy caliber sleeve pipe.
Described crude oil caliber, rock gas caliber are provided with pressure gauge.
Described crude oil caliber is provided with the high-pressure stop valve interface.
The advantage and the effect of the utility model product are as follows:
The utility model product is to adopt oil field shaft mouth output liquid crude as companion's thermal medium, make it to flow through and mix output with crude oil after the whole rock gas delivery nozzle of adjustable in pressure is heated to more than 5 degrees centigrade to rock gas, to reach the purpose of rock gas being thawed, accompanying heat.The crude oil input end of this device adopts the heavy caliber sleeve pipe to be connected on the crude oil pipeline to increase heat exchange area.And the rock gas delivery nozzle that adjustable in pressure is whole places the former oil outlet end in the oil gas mixing chamber, to reach best heat exchange effect.For prevent pumping unit break bar, stop well, respectively install an one-way valve additional at the outlet end and the rock gas delivery nozzle place of this device crude oil import, rock gas caliber, in case stop well and Outer Tube crude oil and rock gas backflow pollution environment.The utility model product structure is simple, be convenient to install, the regular maintenance amount is little, and can adjust, reduce working strength of workers to the pressure that the oil field shaft mouth rock gas exports pipeline to.
