Description
Technical field
The present invention relates to oil recovery technique field, oil field, particularly a kind of additive of injection water of WIW is a kind of additive that can reduce the flushing operational pressure.
Background technology
At present, in the low permeability oil field oil recovery process,, cause the reservoir fluid rate of permeation very low, make the fluidic percolation law depart from Darcy's law, have the trigger pressure gradient, thereby the development difficulty of reservoir strengthens because the throat radius of reservoir is less.Even well pattern can be controlled sand body, this part stratum reserves still is difficult to set up effective driving system.In addition, also cause water filling stratum water-retaining capacity poor, injection pressure is high.
The Chinese patent publication number is: CN1560182.A kind of amendment with nearly well augmented injection effect is provided; Form by Tai-Ace S 150, calcium chloride, quicklime, formaldehyde and water, wherein: Tai-Ace S 150 content is 5~10%, calcium chloride content is 3~5%, calcium oxide content is 0~2%, formaldehyde content be 0.5~2.0% and water-content be 68~82%.Amendment has nearly well augmented injection and well profile control dual function far away.And can reach the demands of different of profile control and augmented injection through the content of quicklime in the adjustment system, applicable to the stratum of high-temperature.If low permeability oil field is carried out profile control, the IR of WIW is improved more than 20%, the moisture decline of corresponding oil well is more than 5%, and has preparation and construction is simple, the advantage that cost is low.
The Chinese patent publication number is: CN1556169.A kind of purposes that relates to the unit molecule quarternary ammonium salt compound as clay stabilization, anti-swollen, sand control and unblocking and injection increasing preparation is provided.It can make stratum clay and mineral stablize; Both can prevent clay swelling; Can improve the perviousness of stratum (especially low-permeability oil deposit) again, thereby improve the sand control and the imbibition effect of intensified injection of wells effect and oil well significantly, and can extensively be employed at nearly all stratum mineral and oil field.Its method of use is two or more the mixture with independent a kind of this compound or their different ratioss, is 1 * 10 with its mass concentration in the liquid of stratum
4~1 * 10
5The amount of mg/L is used.
The Chinese patent publication number is: CN1451842.A kind of method of reducing starting pressure of low permeability oil field is provided.Carry out according to the following steps: at first the injection water at 0.1~0.9 times of volume of voids adds tensio-active agent, and surfactant concentrations is 0.1~10%; Then intermittence or continuous mode the above-mentioned aqueous solution is injected in the oil reservoir by WIW.The above-mentioned injection water that contains tensio-active agent also is added with salt or alkali, the concentration of said salt or alkali≤2%.The aqueous solution and crude oil that the tensio-active agent that this invention is selected is mixed with can form low interfacial tension (10
-4~10
-1MN/m), can reduce trigger pressure significantly and increase substantially the relative permeability of oil reservoir.Have and to employ the reserves that to employ originally, increase workable reserve, can increase the low-permeability oil well yield simultaneously, slow down the moisture ascending amount of low permeability pay, reduce advantages such as sleeve pipe damage.
Summary of the invention
The objective of the invention is: a kind of Gemini quaternary-ammonium-salt water injection increasing agent is provided; Toward the Gemini quaternary-ammonium-salt water injection increasing agent of the even adding 0.05~0.2% of injection water, through reducing wettability, inhibition clay swelling and the bacteria growing inhibiting etc. of oil water interfacial tension, change rock.Improve the percolation ability that injects water, reach the purpose of low permeability oil field step-down augmented injection.
