Description
Technical field
Various fluid ends can be matched with the present invention relates to a kind of, are applied to oil field and various conveying high-pressure liquid field low pressure
The vertical reciprocation pump power end of more spherical surfaces connection of the pressurized water injection technique of feed liquor or high pressure feed liquor, and application have the power end
Water injecting pump, realization meets oil field low in and high out and high into the individual well waterflooding requirement being higher by.
Background technology
The power end of conventional reciprocating pump is crankshaft connecting rod system, is moved back and forth.Reciprocating pump can be divided into it is horizontal and vertical,
But it is all made of bent axle, connecting rod, crosshead, the plunger of intermediate extension bar and fluid end is attached, and is revolved by electric-motor drive bent axle
Turn.Connecting rod rotates back and forth in the crank of bent axle, drive crosshead, intermediate bar, plunger move back and forth to fluid end into
Liquid, tapping valve, imbibition discharge opeing process complete the function of reciprocating pump.
The injection pressure that part well often occurs in secondary oil recovery water injection technology in oil field at present increases and notes and do not intake, this
When can generally carry out pressurized water injection technique to solve, the equipment of pressurized water injection substantially uses following：Plunger type hydraulic resistance balance is horizontal
Reciprocating pump, more piece centrifugal pump, pressure differential hydraulic piston pump and hydraulic balance pump etc., press inlet pressure and outlet pressure it
Between pressure difference carry out hydraulic resistance balance means, the lubricating condition for meeting power end movement parts do not make the power end by imbalance and
Fever influences operation.
The technique of pressurized water injection generally uses more well augmented injections, and augmented injection is carried out by an equipment after arranging similar pressure well.
Reciprocating type plunger boosting water injection pump application finally is most universal in conventional augmented injection equipment, and efficiency is also higher than relative device.But disadvantage
Be pressure difference unbalance factor use scope it is narrow, the pressure difference imbalance will have a direct impact on the normal operation of the equipment.Pressure difference is exactly
Outlet pressure subtracts the difference between inlet pressure, which is often the design considerations of booster pump, because the pressure difference is used according to oil field
The geological condition that family provides, it is difficult to accomplish the pressure difference provided and actual pressure differential value finally in pump operation reach it is certain just
True property, or even can only achieve 50% or less.
Since current concentration water filling, the more well water injection technologies of pump have become the fact, to realize that green, environmentally friendly oilfield safety are arranged
It applies and exactly realizes that ground without high casting die, carries out individual well list note, improves efficiency, be the behave of vast oil field upgrading synergy.Oil simultaneously
Field one pumps the low in and high out water filling of more wells and water flooding regime is concentrated all to need to build water-injection station mostly, additionally arranges high pressure line, high pressure gate
Equal system flows, are all the items with high investment of oilfield surface construction.Therefore oil field will realize individual well list note and individual well augmented injection process, come
Complete the displacement of reservoir oil task for the well that oil field under-injected well and note are not intake.Well head set up individual well water filling can from water-injection station to well head it is all auxiliary
If the manifolds part such as low-pressure line and valve, it can be that very big fund is saved in oil field in this way, also lower each road high-voltage safety wind
Danger.Therefore it develops and a kind of being applicable in live individual well arrangement installation, can be universally used in well head low in and high out or high into the water injection technology being higher by
Power end and water injecting pump it is imperative to substitute existing concentration water filling or the more well water fillings of pump.
