The foam generator comprises a main pipe, an air inlet pipe, an air distribution pipe, a liquid inlet pipe, a front check ring, at least one filler and an outlet pipe, wherein the air pipe and the outlet pipe are located at two ends of the main pipe respectively; the air distribution pipe is arranged in the main pipe and connected to the air inlet pipe; a plurality of air holes are formed in the pipe wall of the air distribution pipe; the liquid inlet pipe is located on the side of the main pipe near the air inlet pipe; the filler is located in the main pipe; and the front check ring is located at one end of the filler near the air distribution pipe.
Description
Technical field
The utility model relates to aerated fluid technical field, particularly a kind of foam maker.
Technical background
Aerated fluid be take water as liquid phase, the gas (air, nitrogen, natural gas, carbon dioxide etc.) of take be gas phase, the two-phase fluid that gas, liquid two-phase are thoroughly mixed to form.Liquid can be clear water, seawater or oil field waste, form the water base foam liquid of low-density, have density lower than water, viscosity higher than characteristics such as water, simultaneously due to the characteristic of above-mentioned gas-liquid two-phase fluid make its have carrying capacity strong, to advantages such as reservoir formation injury are very little.
At present, aerated fluid technology is more and more applied in oilfield operation engineering, utilize aerated fluid to carry out profile control and water plugging, acidifying strata, well cementing of cement, pressure break, sand-flushing, drilling well, water pumping gas production, foam steam flooding etc., and obtained good achievement.
For the foam maker of current use, medium is corrosive to generator, and it is lower to bear pressure, and versatility is poor, and foam quality is on the low side.
Utility model content
The utility model embodiment provides a kind of foam maker, can bear high pressure, and versatility is good, and the aerated fluid of generation is uniform and stable.
A kind of foam maker that the utility model embodiment provides, it is characterized in that, comprise supervisor, air inlet pipe, gas-distribution pipe, feed tube, front back-up ring, at least one filler and outlet, wherein said air inlet pipe and outlet lay respectively at described supervisor two ends, and gas-distribution pipe is positioned at supervisor inside and is connected with air inlet pipe, is distributed with a plurality of pores on gas-distribution pipe tube wall, feed tube is positioned at supervisor side, near air inlet pipe, it is inner that filler is positioned at supervisor, and front back-up ring is positioned at filler near gas-distribution pipe one end.
Wherein, described supervisor, air inlet pipe, gas-distribution pipe, feed tube and outlet all adopt stainless steel.
Wherein, described at least one filler is two.
Wherein, when described at least one filler is while being two or more, described adjacent two filler textures are interlaced.
Wherein, further comprise high pressure flange, described high pressure flange connects described supervisor and outlet.
Wherein, further comprise rear back-up ring, described rear back-up ring is positioned at filler near outlet one end.
A kind of foam maker that the utility model provides, abundant mixing and the cutting to mixture by gas-distribution pipe and filler, can produce uniform and stable aerated fluid.
Accompanying drawing explanation
Figure 1 shows that the structural representation of the foam maker that the utility model embodiment provides.
Figure 2 shows that the filling-material structure schematic diagram of the foam maker that the utility model embodiment provides.
Figure 3 shows that the structural representation of the foam maker that the utility model one embodiment provides.
The specific embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model embodiment is clearly and completely described.
Figure 1 shows that the structural representation of the foam maker that the utility model embodiment provides.As shown in Figure 1, this foam maker comprises: air inlet pipe 1, gas-distribution pipe 2, feed tube 3, front back-up ring 4, be responsible for 5, filler 6(there is shown four) and outlet 7, wherein said air inlet pipe 1 and outlet 7 lay respectively at described supervisor's 5 two ends, gas-distribution pipe 2 is positioned at supervisor 5 inside and is connected with air inlet pipe 1, on gas-distribution pipe 2 tube walls, be distributed with a plurality of pores, feed tube 3 is positioned at supervisor 5 sides, near air inlet pipe 1, filler 6 is positioned at supervisor 5 inside, front back-up ring 4 is positioned at filler near one end of gas-distribution pipe 2, for fixing filler.
Wherein, be responsible for 5, air inlet pipe 1, gas-distribution pipe 2, feed tube 3 and outlet 7 all adopt stainless steel, makes whole foam maker can bear high pressure, versatility is good.
The gas-liquid two-phase fluid of high pressure enters respectively foam maker, gases at high pressure enter into gas-distribution pipe 2 from air inlet pipe 1, simultaneously, highly pressurised liquid tangentially enters from feed tube 3, on the tube wall of gas-distribution pipe 2, there are a plurality of little pores to make fully to mix from gas-distribution pipe 2 gas and feed tube 3 highly pressurised liquid out out, then enter into filler 6.
In the utility model one embodiment, filler 6 is by one group of media assemblage, adjacent two filler textures are interlaced, as shown in Figure 2, adjacent two filler 6a and 6b, 6b and 6c, 6c and 6d texture are interlaced angled, and the gas-liquid mixture producing like this can fully be cut, and mixes, thereby produced uniform and stable aerated fluid, through outlet 9, discharged.
A kind of foam maker that the utility model provides, abundant mixing and the cutting to mixture by gas-distribution pipe and filler, can produce uniform and stable aerated fluid.
Figure 3 shows that the structural representation of the foam maker that the utility model one embodiment provides.As shown in Figure 3, this foam maker, on basis embodiment illustrated in fig. 1, further comprises: high pressure flange 8 and/or rear back-up ring 9.High pressure flange 8 connects supervisor 5 and outlet 7, is convenient to dismounting, to change filler.Rear back-up ring 9 for the common fixedly filler 6 of front back-up ring 4.
A kind of foam maker that the utility model one embodiment provides, can connect supervisor by dismounting and change filler with the high pressure flange of outlet, has extended the service time of foam maker, improves the quality that produces foam.
Above-described embodiment is only explanation technical conceive of the present utility model and feature; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement etc., within all should being included in protection domain of the present utility model.
