Technical field
The present invention relates to a kind of oil-water two-phase flow flowing law simulator, the invention belongs to the technical field of oil-gas field development.
Background technology
It is implement waterfrac treatment to construct at present for the well stimulation being difficult to the hyposmosis with usual manner exploitation, fine and close hydrocarbon-bearing pool is mainly taked, namely a large amount of fracturing liquid is injected to stratum with the injection pressure exceeding formation rock parting pressure, the fracturing liquid that high pressure injects makes stratum produce man-made fracture, adopt the mode crackle preventing injecting spherical shape propping agent to close simultaneously, after construction terminates, under the supporting role of propping agent, not closed man-made fracture serves as oil gas flow passage, reaches volume increase object.
If when waterfrac treatment, link up the water layer near reservoir, after entering production phase, it is possible to there will be oil-water two-phase flow, phase also may enter profit same term to the oil gas well not carrying out waterfrac treatment construction after manufacture, profit flowing at this time is exactly liquid-liquid diphasic flow, and research oil-water two-phase flow rule is conducive to rationally arranging drawdown pressure and prediction profit output.
At present also not for the simulator of liquid-liquid diphasic flow flowing law, liquid-liquid diphase flowing has certain singularity, two-phase may mixed phase in vigorous stirring upon mixing, do not reach the object of two-phase simulation, simultaneously the density of the two, interfacial tension, discharge capacity are bigger on the impact of experimental result, need when simulating to consider the respective physical properties of profit and experiment parameter setting, it is an object of the invention to provide a kind of experimental installation that can simulate oil-water two-phase flow flowing law under different densities, interfacial tension, discharge capacity, viscosity parameter.

Fig. 2 is oil intermediate receptacle, water intermediate receptacle structural representation.
Shown in figure: 1-oil injection pump, 2-water injection pump, 3-oil intermediate receptacle, 4-water intermediate receptacle, 5-injection tube, 6-fillup valve, the visual flat board of 7-, 8-outlet valve, 9-vent pipe, 10-pipe connecting.
Embodiment
Below in conjunction with embodiment, the present invention will be further described in detail.
As shown in Figure 1, 2, a kind of oil-water two-phase flow flowing law simulator of the present invention, comprises oil and promotes device, water to promote device, oil intermediate receptacle 3, water intermediate receptacle 4, injection tube 5, fillup valve 6, visual dull and stereotyped 7, outlet valve 8, vent pipe 9, pipe connecting 10; Described oil intermediate receptacle 3, water intermediate receptacle 4 are hollow and the container with piston, and described oil promotes device to be connected with oil intermediate receptacle 3, and described water promotes device to be connected with water intermediate receptacle 4; Described fillup valve 6 is arranged on pipe connecting 10; Described injection tube 5 one end is connected with pipe connecting 10, and the other end is connected with oil intermediate receptacle 3, water intermediate receptacle 4 respectively; Described visual dull and stereotyped 7 is the transparent plexiglass plate of hollow, and described visual dull and stereotyped 7 one end are connected with pipe connecting 10, and the other end is connected with vent pipe 9, and described outlet valve 8 is arranged on vent pipe 9.
What wherein the conjunction number of fillup valve 6 and pipe connecting 10 was is multiple, and the use procedure of such the present invention is: experimentally need opening and closing fillup valve 6, and then regulates the hole count injected; As shown in Figure 1 and Figure 2, piston in oil intermediate receptacle 3, water intermediate receptacle 4 is positioned at bottom oil intermediate receptacle 3, water intermediate receptacle 4, piston superjacent air space at oil intermediate receptacle 3, water intermediate receptacle 4 is equipped with You Heshui respectively, device, water is promoted to promote device to promote piston to move up by oil, piston promotes oil and water to enter into injection tube 5 again, oil, water is injected by oil intermediate receptacle 3, water intermediate receptacle 4, it is possible to prevent to stop profit mixed phase directly by the vigorous stirring of the fashionable generation of infusion; Enter into the oil of injection tube 5 and water mix after by fillup valve 6, pipe connecting 10, enter into visual dull and stereotyped 7, oil-water two-phase flow flowing law can be observed in visual dull and stereotyped 7; Profit is discharged by vent pipe 9 after being full of visual dull and stereotyped 7, and the process discharged from vent pipe 9 is used for the flowing of simulating oil-water in pit shaft. As shown in Figure 1, it is preferable that enforcement mode to be described fillup valve 6 be 5 with the number of pipe connecting 10.
The present invention injects oil and water by intermediate receptacle, it is possible to effectively prevents profit mixed phase with vigorous stirring, reaches good simulate effect; Can adjusting injection hole count, simulate effect is more close to true stratum; By selecting oil, the water of different physical properties, the two phase flow rule under simulation different densities, interfacial tension, viscosities can be reached.
In order to the flowing law can simulated under different profit discharge capacity ratio, then need to adjust the injection speed of oil, water, it is thus preferred that enforcement mode be that described oil promotes device for oil injection pump 1, described water promotes device to be water injection pump 2. Like this by oil injection pump 1, water injection pump 2 from oil intermediate receptacle 3, water intermediate receptacle 4 below ingress inject displacing liquid, piston can be promoted to move up, piston promote again oil and water enter into injection tube 5; So regulating the injection speed of oil injection pump 1, water injection pump 2, the object regulating oil, water to inject discharge capacity ratio can be reached.
