Abstract
The invention relates to an injection process of a polymer or ternary fluid proportion adjusting pump. The process comprises following steps of: transporting 5000mg/L of mother liquid delivered from a preparation station to an inlet of a proportion adjusting pump 2 through a filter 1, pressurizing the mother liquid to 12 to 20 MPa by the proportion adjusting pump 2 dragged by a motor 3, dividing the mother liquid from three outlets through the proportion adjusting pump, independently arranging a mother liquid valve bank 4 on each outlet, measuring the high pressure mother liquid by the mother liquid valve banks 4, mixing high pressure water of a high pressure water valve bank 5 and the high pressure mother liquid in a static mixer 6, preparing into 1000mg/L of target liquid after mixing in the static mixer 6 and fully mixing, then transporting the mixed liquid outside the station, and injecting the mixed liquid to an injection well by an injection pipe network outside the station. Through applying the injection process disclosed by the invention, the number of injection pumps is reduced by 65%, the construction area is greatly reduced, the investment is saved by 8%, the shear degradation to the mother liquid in the link of a flow regulator is reduced, and the sticking loss is reduced about less than 10%.
Description
Technical field
The present invention relates to a kind of injection technology in oil recovery field, oil field, especially a kind of polymer or ternary liquid proportional are regulated infusion and are gone into technology.
Background technology
What the whole employings of poly-initial stage injection station were annotated in the oil field is single pump individual well technology, the advantage of single pump individual well technology is: every pump is corresponding mutually with pressure, the flow of every mouthful of well, flow and pressure need not throttling significantly when regulating, and the energy utilization is abundant, and individual well injection allocation parameter ratio is easier to adjust.Shortcoming is: number of devices is many, and the injection station floor space is big, the construction investment height, and maintenance is big, is unfavorable for resettlement.After adopted a conventional pump multiple well technology and a usefulness again, its advantage is: number of devices is few, the injection station floor space is little, work simplification, maintenance workload is few, is beneficial to resettlement.Shortcoming is: total system is divided into several injection pressures, and there is the certain pressure loss in Flow-rate adjustment, and has increased certain viscosity loss, and the existence of individual well Flow-rate adjustment interferes with each other, and has increased the investment of flow regulator.
Summary of the invention
In order to solve the deficiency that exists in the background technology, the invention provides a kind of polymer or ternary liquid proportional adjusting infusion and go into technology, the more conventional single pump individual well technology of the present invention is compared, and injection pump quantity reduces 65%, and building area significantly reduces, and reduces investment outlay about 8%.The many wells of a more conventional pump, saved mother liquor header and flow regulator that the individual well mother liquid flow rate regulates and distributes link, simplified the robot control system(RCS) of injection station, reduced of the shear degradation of flow regulator link mother liquor, the sticking damage approximately decreased 10～20% less than the many wells of 10%, one pump are sticking.
The present invention adopt technical scheme be: this technology comprises the following steps: that the mother liquor of the defeated 5000mg/L that comes of preparation station enters than row through filter 1 and regulates pump 2 imports, the ratio row that drag via motor 3 are regulated pump 2 mother liquor are pressurized to 12～20MPa, be divided into 3 outlets by regulating pump 2 than row, each outlet all is provided with mother liquor valve group 4 separately, the high pressure mother liquor is through the metering of mother liquor valve group 4, water under high pressure with high pressure water valve group 5 enters static mixer 6 mixing then, be hybridly prepared into the purpose liquid of 1000mg/L through static mixer 6, and mix and fully evenly transport to outside the station, injection pipe network outside standing is to injecting well, wherein mother liquor valve group 4 is by ball valve, electromagnetic flowmeter, ball valve and flap valve serial connection form, and high pressure water valve group 5 is composed in series by flow meter and motor operated valve.
Compare with existing method, the present invention has the following advantages: its technology is liquid pipe on from the feed flow main to pump, through the pump front filter, enter the injection pump suction side again, delivery side of pump is divided into 3, each outlet all is provided with ball valve, electromagnetic flowmeter, ball valve and flap valve separately, and the high pressure mother liquor mixes at static mixer with water under high pressure through metering, transports to 3 mouthfuls of outer injection wells of station through control.Whole device is arranged on 1 can separate on the end sled removable utilization again.The more conventional single pump individual well technology of the present invention is compared, and injection pump quantity reduces 65%, and building area significantly reduces, and reduces investment outlay about 8%.The many wells of a more conventional pump, saved mother liquor header and flow regulator that the individual well mother liquid flow rate regulates and distributes link, simplified the robot control system(RCS) of injection station, reduced of the shear degradation of flow regulator link mother liquor, the sticking damage approximately decreased 10～20% less than the many wells of 10%, one pump are sticking.

The specific embodiment:
The invention will be further described below in conjunction with embodiment:
As shown in Figure 1, a kind of polymer provided by the present invention or ternary liquid proportional are regulated infusion and gone into technology and comprise: the mother liquor of the defeated 5000mg/L that comes of preparation station is metered into mother liquor storage tank device 1 buffering through control and stores.Mother liquor is by the outlet of mother liquor storage tank device, enter mother liquor feed flow main, distribution is through the bend pipe that is flexible coupling of each branched pipe, take to keep feed flow state on the static pressure, the feed flow pressure head is located in 3.5m～6m scope, mother liquor enters than row through filter 1 and regulates pump 2 imports then, regulates pump 2 supercharging 16MPa via the ratio row that motor 3 drags, and is divided into 3 outlets (each outlet all is provided with ball valve, electromagnetic flowmeter, ball valve and flap valve separately) by regulate pump 2 than row.The high pressure mother liquor is composed in series by 3 groups of flow meters and motor operated valve with high pressure water valve group 5(then through the metering of mother liquor valve group 4).The water under high pressure (clear water, oil-polluted water or high pressure binary water) of control and metering enters static mixer 6 together to be mixed, be hybridly prepared into 1000mg/L(or the needed concentration of other geology through static mixer) purpose liquid, and mix fully evenly, mixing nonuniformity coefficient is controlled at less than 5%, the injection rate of purpose liquid and concentration error all are controlled at less than ± 5%, and the damage control of whole activities polymer liquid solution viscosity is in 10% scope.Purpose liquid is outside the station is transported in control, and the injection pipe network outside standing is to injecting well.
