Description

A kind of ultra-low penetration oil field high pressure oil displacement agent injection technology device
Technical field
The utility model relates to oil and gas exploration equipment, especially a kind of ultra-low penetration oil field high pressure oil displacement agent injection technology device.
Background technology
Along with the development of petroleum natural gas exploration, exploitation is dropped in more and more hypotonic, ultralow oil impregnate gas fields, and low permeability oil field limit Di Shui is inactive, and the consumption of natural elastic energy is fast, and the natural production ability is very low.One side oil reservoir starting pressure height, the water injection well water absorbing capacity is low, and it is slow that corresponding producing well pressure recovers, and is difficult to see effect, and the oil well recovery ratio is all very low, occurs annotating not advance, the universal phenomenon of can not adopting, oil field integral body recovery ratio is lower.On the other hand, because the difference of matrix and crack system percolation ability is big, formation fracture exists makes the water filling water breakthrough serious, causes the quick water logging of oil well, and oil displacement efficiency is low, and this phenomenon is seriously restricting the effect of water flooding and additional stratum energy.
Summary of the invention
The purpose of this utility model has provided a kind of ultra-low penetration oil field high pressure oil displacement agent injection technology device that improves oil displacement efficiency, improves waterflood efficiency.
The purpose of this utility model is to realize like this, a kind of ultra-low penetration oil field high pressure oil displacement agent injection technology device, it is characterized in that: comprise motor, high pressure accurate measurement pump, unidirectional non-return protective valve, high pressure valve, stirring Agitation Tank, stir and tremble Agitation Tank and divide two-way to be connected with injection pipe network, the one tunnel directly is connected on the distributing room for water injection injection pipe network by high pressure valve; Another road links to each other with unidirectional non-return protective valve through high pressure accurate measurement pump discharge by high pressure accurate measurement pump, is connected on the distributing room for water injection injection pipe network by high pressure valve by unidirectional non-return protective valve.
Described high pressure accurate measurement pump adopts the double pump header structure.
The utility model has the advantages that: comprise five parts such as motor, high pressure accurate measurement pump, unidirectional non-return protective valve, high pressure valve, stirring Agitation Tank.Stir and tremble Agitation Tank and can feed water pump with water-injection station and link to each other; also can come water pipeline to link to each other with distributing room for water injection; come water to provide by pumping plant and stir the dosing water of trembling Agitation Tank; stirring Agitation Tank is connected with measuring pump; the measuring pump outlet links to each other with unidirectional non-return protective valve; unidirectional non-return protective valve prevents the influence of down-hole back pressure to pump, guarantees the normal and accurate measurement of pump operation.Be connected on the distributing room for water injection injection pipe network by high pressure valve then.
High pressure accurate measurement pump adopts the double pump header structure, and economical and practical, floor space is little, superior performance.Quantitatively output also can be regulated flow, one of positive and negative percentage of precision Gao Keda arbitrarily when pump stops.Be applicable to that pumping temperature is-30~120 ℃, viscosity is 0.3~800mm 2The medium of/s.Operating pressure reaches as high as 40MPa.The effect of the utility model device is can satisfy ultra-low penetration oil field height to force down the needs that discharge capacity is injected oil displacement agent.
