Specific implementation mode
In compliance with the above technical solution, as shown in Figures 1 to 4, the invention discloses a kind of eccentric rotary oscillation mixing pump groups
Oil and gas multiphase flow supercharging is prized, including the oil and gas multiphase flow pressure charging system being integrated in pry bracket, the system include：At least one set of mixing pump
Group, the intake pipeline drawn from well head are connected to the mixing pump group, the object come to intake pipeline conveying by mixing pump group
Matter carries out after mixing defeated processing, is transported by export pipeline；On the intake pipeline, along close to the direction of mixing pump group
It is disposed with import high voltage protective motor-driven valve 5, filter device, import motor-driven valve, imported valve and import shockproof pressure gage,
It is disposed with Outlet check valves, outlet valve, outlet high pressure in the direction of the export pipeline upper edge far from mixing pump group
Protect motor-driven valve 4 and outlet shockproof pressure gage 1.
The present invention whole system by the way of skid, be fully integrated into a pry bracket, be conducive to whole installation,
Transport, layout and design, have the characteristics that highly integrated property.This whole supercharging sled proposed by the present invention is with applicant early period
Achievement in research, it is entitled：" a kind of multinomial oil-gas mixed delivery pump of bias rotary oscillation ", the reality that Authorization Notice No. is CN202646001U
With what is carried out on the basis of new patent.That is, mixing pump group mentioned in the present invention, is slowed down by fire-proof motor, horizontal helical gear
What case and described this several major of the multinomial oil-gas mixed delivery pump of eccentric rotary oscillation were constituted.Fire-proof motor is connect with reduction box,
Reduction box connects the shaft of oil-gas mixed delivery pump by shaft coupling, and it is mixed defeated to carry out pressurization to oil, gas for driving oil-gas mixed delivery pump rotation.
The conveying substance that the present invention is directed to is the crude oil just produced from oil field shaft mouth, natural gas and water, various dopes
Matter and solid particle, using mixing pump to these substances carry out pressurization it is mixed it is defeated after, carried out by single pipeline it is mixed defeated over long distances,
In order to subsequent separating treatment process.The basic structure of the present invention includes mixing pump group (hereinafter referred to as pump group), the number of pump group
Amount should be depending on oil well output.Intake pipeline is drawn from well head, is connected to the input terminal of pump group, it would be desirable to which mixed defeated substance carries out
Then pressurized treatments carry out long distance delivery from the output end of pump group by export pipeline.It is that cannot achieve length only by pump group
Distance is mixed defeated, to being disposed on intake pipeline in this present invention：
Import high voltage protective motor-driven valve 5, the motor-driven valve are prevented for being closed to intake pipeline in export pipeline superpressure
Only more liquids enter in pump group and cause the damage of bigger；
Filter device, some large granular impurities being primarily used in filtering crude oil, prevents pipeline from blocking；This implementation
In example, filter device is arranged two groups, and each group of filter device includes sequentially connected filter inlet valve (first filter
Imported valve 7, the second filter inlet valve 8), filter (first filter 9, the second filter 10) and filter outlet
Valve (first filter outlet valve 12, the second filter outlet valve 13), two set filters are arranged in parallel；Two groups of mistakes are set
The purpose for filtering device is that filter device needs periodic cleaning, when needing cleaning at one group, can first pass through another group and be filtered；
Imported valve therein, outlet valve are closed in maintenance, are then removed filter and are cleaned, replaced.
Import motor-driven valve, is the control valve for controlling the liquid in pipeline and whether entering in pump group, and use is electronic
Valve can carry out automatically controlling, and after import motor-driven valve is opened, the liquid in pipeline be allowed to carry out pressurized treatments by pump group；By
Generally it is arranged multigroup in prizing upper pump group at one, each group of pump group can coordinate different pre- so all there are one import motor-driven valve
First Provisioning Policy, to be turned on and off some pump group, to adapt to current yield or reply high pressure, the operating mode of high flow capacity.Separately
Outside, the automation, it can be achieved that controlling is controlled by import motor-driven valve, enable entire pump group it is automatic, it is energy saving, efficiently run.
Imported valve is a hand-operated valve, is closed to carry out manually pipeline when import motor-driven valve breaks down；
Import shockproof pressure gage prevents hypertonia from causing the damage of pump group to monitor line pressure.
In the present invention Outlet check valves, outlet valve are disposed in direction of the export pipeline upper edge far from mixing pump group
Door, outlet high voltage protective motor-driven valve 4 and outlet shockproof pressure gage 1, the wherein effect of Outlet check valves and import check valve class
Seemingly, it is both ends for closing its corresponding pump group, to realize switching, unlatching, closing between different pump groups etc.；Outlet valve
As being with the effect of imported valve, it to be used for maintenance process；It is then corresponding with import shockproof pressure gage to export shockproof pressure gage 1,
While monitoring pressure, it can be used for positioning pipeline or pump group failure, in order to maintenance process.
Due to having used oil-gas mixed delivery pump in the present invention, this pump is a kind of rotary eccentric positive displacement pump, and bias is used in pump
Rotor structure can be brought rapidly up boosting when oil gas is relatively low, cause to pump interior temperature and pressure excessively high；And eccentric rotor is in long-term work
During work, can inevitably wear, be especially currently entering pump in substance be with gas be it is main when.To understand
Certainly this problem is additionally provided with high pressure reflow device 18 in oil and gas multiphase flow pressure charging system in the present invention, which utilizes pipeline one
End is connected on the intake pipeline between import shockproof pressure gage and mixing pump group, and the other end is connected to outlet valve and outlet is high
On export pipeline between pressure protection motor-driven valve 4；The extraction unit from export pipeline of high pressure reflow device 18 is in charge of the liquid in line
Substance, and will be on this operative liquid substance water conservancy diversion to intake pipeline.
Substance in intake pipeline has crude oil, natural gas and water, various thick substances and solid particle, liquid here
Substance is crude oil and water therein.Pump group is had already passed through the crude oil and water of mixed defeated pressurization using pipeline by high pressure reflow device 18
Sub-fraction imported into the output end of pump group again, can guarantee so no matter the either high oil gas of substance produced in current well head
Than still low oil-gas ratio, can make play to oil and gas multiphase flow so always with the presence of liquid in oil-gas mixed delivery pump
The lubrication cooling of pump acts on, and can also improve oil-gas ratio.
