Abstract
The utility model relates to a high-efficiency gas-liquid centrifugal pump which comprises a pump assembly, a clamping tube, a pump shell, an impeller, a guide shell, a pump shaft and a pump block assembly. The pump assembly and the pump block assembly are respectively arranged on both ends of the pump shell; and in the pump shell, the pump shaft goes through the pump block assembly, the clampingtube, the impeller and the guide shell from the pump assembly, and is arranged on the pump shaft. The high-efficiency gas-liquid centrifugal pump is characterized in that gas-containing well liquid isformed into similar single-phase liquid and enters a submersible centrifugal pump, the absorption conditions of the centrifugal pump are greatly improved and the centrifugal pump is prevented from air lock, the normal operation of the submersible pump in a high gas-containing oil well is ensured and the output of the highly gas-containing oil well is improved, and is widely applied in oil production process in oil fields.
Description
One, technical field
The utility model relates to petroleum production down-hole oil production pump, particularly a kind of high efficient gas and liquid centrifugal pump.
Two, background technique
At present, Chang Gui Electric Submersible Pump Unit is made up of the flange connection from bottom to top of oil-submersible motor, protector, rotation gas separator (or twin-stage separator), multistage centrifugal pump.For preventing that free gas from entering in the centrifugal pump, existing rotation gas separator makes the gas-liquid mixture high speed rotating by impeller, under action of centrifugal force, liquid enters centrifugal pump through separating husk near being thrown to the separator inwall, and gas enters sleeve pipe along the separating husk of passing through on the decoupler shaft, and the problem of its existence is:
1, conventional separator can only be suitable for gas content under the PIP and account for oil, gas, water three-phase total volume less than 30% oil well, for the oil well of air content＞30%, even use the double stage tandem separator, does not also reach good separating effect.
2, surpass after 200 at oil-gas ratio, the separating effect of twin-stage deaerator is not really desirable, and in a single day a large amount of free gases enters in the centrifugal pump, and it is just more difficult to suck fluid again, and pump efficiency reduces, and forms gas lock when serious, causes underload shutdown.The very low even ordinary production of oil well output in the scene all is difficult to keep.
Three, summary of the invention
The utility model purpose provides a kind of high efficient gas and liquid centrifugal pump; can not only guarantee that the submersible electric pump centrifugal pump runs well in high gassiness oil well; avoid centrifugal pump generation gas lock to shut down; can also make enter oil-submersible centrifugal pump contain gas well liquid as single-phase liquid; improve the suction condition of centrifugal pump greatly; improve high gassiness oil well yield, the shortcoming or the deficiency that overcome effectively or avoid existing in the prior art.
High efficient gas and liquid centrifugal pump described in the utility model comprises the pump head assembly, compresses pipe, pump case, impeller, leads shell, pump shaft and pump seat assembly.Described pump head assembly and pump seat assembly are installed on the two ends of pump case respectively, and pump shaft self-pumping head assembly in pump case compresses pipe, impeller and leads shell and be installed on the pump shaft in turn through the pump seat assembly.
Wherein, described impeller and impeller, lead shell and lead shell, each is opposite, in pairs, alternately be installed on the pump shaft mutually.Described impeller is that the center is provided with the through hole by pump shaft, and circumference is provided with the disc-shaped structure of the middle part projection of inclination and vertically passing discharge orifice.
The utility model has following advantage compared with prior art:
1, the utility model enters in the oil-submersible centrifugal pump the approximate single-phase liquid state of high air containing fluid; improve the suction condition of oil-submersible centrifugal pump greatly, avoid occurring gas lock and shut down, thereby prolong unit working life; improve high gassiness oil well yield, had high economic benefit and social benefit.
2, the utility model has improved the adaptive capacity of Electric Submersible Pump Unit in high gassiness oil well, has enlarged the application of submersible electric pump.
3, the utility model is simple in structure, and it is convenient to implement.
4, optimize the structural parameter of guide vane wheel, the ability that makes guide vane wheel handle free gas improves.
5, optimization is supporting, adds the rotation separator under " high efficient gas and liquid centrifugal pump ", makes high air containing fluid entering " high efficient gas and liquid centrifugal pump " before, carries out pre-separation, to improve the efficient of " high efficient gas and liquid centrifugal pump ".
Four, description of drawings
Fig. 1 is a kind of example structure schematic representation of the present utility model
Fig. 2 is for pressing blade wheel structure schematic representation shown in Figure 1
Fig. 3 is for pressing structure schematic top plan view shown in Figure 2
Five, embodiment:
Consult Fig. 1-Fig. 3, a kind of high efficient gas and liquid centrifugal pump comprises the pump head assembly, compresses pipe, pump case, impeller, leads shell, pump shaft and pump seat assembly.Pump head assembly 1 and pump seat assembly 10 are installed on the two ends of pump case 3 respectively, and pump shaft 8 self-pumping head assembly 1 in pump case 3 compresses pipe 2, impeller 5 and leads shell 7 and be installed in turn on the pump shaft 8 through pump seat assembly 10.
During use, the utility model is installed between the multistage centrifugal pump and separator of submersible electric pump, pass through power cable, ground electrical power is delivered to motor, the rotation of driven by motor oil-submersible centrifugal pump, because the effect of rotary centrifugal force, the well liquid of oil reservoir sucks by efficient rotary separator, air containing fluid carries out the oil gas pre-separation at this, isolated gas enters oil sets annular space, emit sleeve pipe gas by well head venting flow process, the well liquid that separates enters the utility model, and the impeller 5 in the utility model is smashed high air containing fluid bubble, makes well liquid form uniform solution-airmixture, single-phase liquid enters the high efficient gas and liquid centrifugal pump, and the utility model is pressurized to well liquid and enters oil pipe behind the rated head and given rise to ground.
