Abstract
The utility model discloses a nitrogen foam flooding control device. The device comprises a solution tank, wherein a mixer which is used for mixing a foaming agent is arranged inside the solution tank, a liquid inlet and a liquid outlet are arranged on the solution tank, the liquid inlet of the solution tank is connected with a liquid inlet pump through a liquid inlet pipeline, the liquid outlet of the solution tank is connected with a main metering pump through a main liquid outlet pipeline, and an electrical heater which is used for heating the foaming agent is arranged on a tank body of the solution tank in a fixing mode. According to the device, the electrical heater is arranged on the tank body, the foaming agent is not affected by the temperature of an external environment and stirred and mixed uniformly, and then the foaming agent is mixed with nitrogen and subjected to mixing foaming, so that uniform and stable foam liquid is formed and enters a well. The nitrogen foam flooding control device is simple in structure and is applied widely in the technical field of development of oil and gas field and coal bed gases.
Description
Technical field
The utility model relates to a kind of oil field and improves the injectant transfer drive device that recovery ratio is used, particularly a kind of nitrogen foam adjusting driving device.
Background technology
The nitrogen foam pressure break is a new developing technology on the hydraulic fracturing technology basis, is specially adapted in oil gas field and the cbm development process transformation to low pressure, hypotonic and water sensitivity stratum, and the Chinese patent notification number is CN201090200Y; The day for announcing is on July 23rd, 2008, and name is called in ' a kind of nitrogen foam generator ' manual and discloses a kind of foam maker, is made up of air and liquid mixer, one way valve, pressure meter, stop valve, ball valve, liquid feeding pump, piping filter, measuring pump, medicinal cupping, agitator, electrical control cubicles; It is anti-that medicinal cupping is arranged on Electric Appliance Cabinet, and agitator is arranged in the medicinal cupping, and medicinal cupping is connected with measuring pump through piping filter; The medicinal cupping bottom is connected with liquid feeding pump; Access valve under the liquid feeding pump, the measuring pump bottom is connected to air and liquid mixer, one way valve, pressure meter, stop valve respectively, and this structure has realized nitrogen and the living foam of blowing agent hybrid concurrency basically; Be injected into oil well; But this structure carrying is inconvenient, and in the liquid mixing process, blowing agent receives the influence of ambient temperature easily; Foaming process is unstable; Can make foam quality unstable and foam inhomogeneously, and the situation of blowing agent possibly take place to lack in this device of prior art, causes injection rate unstable.
The utility model content
The purpose of the utility model is to provide a kind of nitrogen foam adjusting driving device, to solve foaming process problem of unstable in the prior art.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of nitrogen foam adjusting driving device, comprise liquor box, and the liquor box set inside is useful on the agitator that stirs blowing agent; Liquor box is provided with inlet and liquid outlet; The inlet of liquor box is connected with liquid feeding pump through the feed liquor pipeline, and the liquid outlet of liquor box is connected with main measuring pump through main fluid pipeline, fixedly installs the electric heater that is useful on the blowing agent heating on the casing of liquor box.
The liquid outlet place of described liquor box also is provided with branch's fluid pipeline, is connected with the branch metric pump on the fluid branch line, and the liquid outlet of said main measuring pump and branch metric pump crosses through pipeline.
Liquor box, main measuring pump, branch metric pump, liquid feeding pump all are arranged on the skid plate.
Liquor box is outside equipped with in order to observe the visual content gauge of blowing agent liquid level.
The box house of the utility model is provided with electric heater, makes blowing agent not receive the influence of ambient temperature, and blowing agent mixes, and blowing agent and nitrogen mixed foaming get in the well thereby form even, stable aerated fluid then.
Further, branch's fluid pipeline is set, two measuring pumps measure simultaneously, have increased injection efficiency.
Further, liquor box, main measuring pump, branch metric pump, liquid feeding pump adopt the skid-mounted type structure, and onsite moving is convenient.
Further, casing is provided with visual content gauge, can replenish blowing agent immediately through observing the liquid level of blowing agent in the liquor box, makes mixed process stable, injects stability of flow.
Description of drawings
