Description
Technical field
The present invention relates to one and mix defeated eccentric rotor oil-gas mixed delivery pump for oilfield.
Background technology
The abundantest for some oil field oil field gas resource, owing to upstream and downstream airtight collection technique does not matches, substantial amounts of associated gas is put
Sky, causes waste, environmental pollution and safety problem.Traditional closed gathering uses oil gas to divide defeated, i.e. uses centrifugal pump oil transportation,
Oil pipeline walked by oil；Compressor conveying gas, walks gas pipeline.Along with maturation and the development of screw pump technology, some oil fields actively push away
Wide oil and gas multiphase flow technology, this technology need not a whole set of gas, liquid separation equipment, compressor apparatus and dedicated transport pipeline, utilizes
Original collection transmission pipe network realizes oil and gas multiphase flow, effective pooling of resources, improves oil field enclosed rate, is to reduce the most economical of oil and gas loss to have
The defeated mode of collection of effect.Oil-gas mixed delivery pump is the key equipment in oil and gas multiphase flow technology, is by the infusion function of oil transfer pump and compressor
Air delivery function be integrated in one.The mixing pump that oil and gas multiphase flow technology uses at present has single screw rod and double-screw oil gas mixing transmission pump, exists
Problem be that single screw rod mixing delivery pump is bad higher than 50m3/t effect for gas-oil ratio, and be not suitable with that gas-oil ratio fluctuation range is big and pressure
The operating mode that power is high, causes pump work abnormal；Double-screw oil gas mixing transmission pump adaptation condition is poor simultaneously, faults frequent, maintenance cost
High.
In order to solve the high gas-oil ratio (HGOR) multi-phase mixed delivering of crude oil and associated gas, it is achieved oil-gas closed collection is defeated, the multistage conveying of distance, reduction is built
If investment, and realize well casing gas and reclaim, avoid atmospheric pollution, save social resources, find novel reliable heterogeneous mixed
Defeated device, is one of problem of paying close attention to of those skilled in the art.
Summary of the invention
It is an object of the invention to be difficult to single pipe realizing crude oil, natural gas and water, various viscous substance and solid particle
Line mixes defeated and distance pressure-increasing unit.To achieve these goals, spy provides a kind of eccentric rotor oil-gas mixed delivery pump, the present invention

Logical, oil extraction is discharged from outlet(discharge) flange in entering main shaft by rotor；Outlet(discharge) flange communicates with outlet line, completes continuous print oil-feed
And oil extraction.
Between rotor and slide plate, realize sliding friction by the multiple rows of needle roller of installation be changed into rolling friction, alleviate motor and overcome sliding friction
Output, and can service life of elongated component.
The eccentric rotor oil-gas mixed delivery pump of the present invention has made the biggest improvement on the basis of existing technology, and it is technically characterized by comprising the steps as follows:
1, final drive shaft portion has carried out static balance process by loss of weight, eliminate because of rotary body in rotation process because of barycenter not on axis
The eccentric inertia caused causes the mechanical vibration in final drive shaft portion；Driven shaft portion has carried out static balance process by loss of weight, eliminates
The eccentric inertia not caused on axis because of barycenter in rotation process because of rotary body causes the mechanical vibration in driven shaft portion, at pump
Greatly reduce vibration during overall operation, be that pump housing operation is more steady.
2, input bearing block and outfan bearing block all have an eccentric orfice position, and processing easily realizes with one heart, can guarantee that main transmission axis with
Driven axis parallel.
3, the bearings position of main transmission axis with driven axis is shortened, reduce mechanical vibration further.
4, oil outlet end is discharged from outlet(discharge) flange, has bigger cushion space therein, reduces the pulse phenomenon of the pump housing；Additionally axle
Intensity is greatly increased, and reduces the rotational deformation of axle, improves the depth of parallelism of main transmission axis and driven axis.
Multiple rows of needle roller that 5 rotors are installed greatly reduces force of sliding friction, makes the life-span of parts be greatly improved.
The performance characteristics of the eccentric rotor oil-gas mixed delivery pump of the present invention is:
1, solve crude oil, natural gas and water, various viscous substance and solid particle be difficult to single pipeline mix defeated and pressure-increasing unit with
Gas-liquid delivery problem under a difficult problem for the multistage conveying of distance, and big gas-oil ratio operating mode.
2, this pump can realize low temperature conveying, it is not necessary to Oil-gas Separation, is not required to pressure charging system, directly can carry with well site or gathering station,
Simplifying technique, decrease cost, the energy-saving and cost-reducing oil well that can realize is without discharge, pollution-free, by whole for emptying gas centralized recoveries.
3, this structure is a kind of displacement pump, and accuracy is high, has taken into account the common performance of oil pump and air compressor, can realize from structure
The operation of oil field digitized positive battery metering conveying.
4, this pump achieves the continuous oil extraction of synchronization, and output liquid continuous uniform, pressure stability, disturbance are little, to the liquid of sensitivity not
The change of composition can occur, and efficiency is high, power consumption is little.
5, running speed is low, can realize noiselessness and pollute.
6, pressure can be automatically adjusted with output channel resistance, and discharge capacity can be according to practical situation by regulation rotating speed speed, under rated discharge
Increase or reduce certain amplitude.
7, can be at life-time service under rugged environment.
8, frame for movement is simple, and the bodily form is little, and I&M is convenient.
9, the unlatching of pump and stopping are not required to any less important work and complete.
10, the failure rate is low of pump, few easy workout part.
