Abstract
The invention provides a high-activity oil displacement agent, comprising cationic Gemini surfactant, anionic surfactant and water. The weight ratio of the cationic Gemini surfactant and the anionic surfactant is 1:5 to 1:10, and the weight of the water is equal to the total weight of the cationic Gemini surfactant and the anionic surfactant, wherein the cationic Gemini surfactant is selected from dual-hexadecyl dimethyl ammonium bromide; the anionic surfactant is selected from alkyl naphthalene sulfonate formaldehyde condensation compound; the water is tap water or recycled oil field sewage. The oil displacement agent needs no alkalified additive, resists high temperature, and has good salt-tolerant capability.
Description
Technical field
The present invention relates to the chemical oil displacement agent in a kind of oil production.
Background technology
For improving oil recovery, one of chemical process that adopts is to use oil-displacing agent, the on-the-spot oil-displacing agent great majority that use in oil field are anion surfactant or anion surfactant and the composite mixture of nonionogenic tenside at present, and in use all add additive alkali, be beneficial to reduce oil/water termination tension force.But being used of alkali cause injuries such as oil layer blocking, permeability plugging easily, and emulsification of crude oil is serious, and extraction liquid profit is difficult to separate fully, for the crude refining in downstream brings certain difficulty.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of high reactivity oil-displacing agent is provided, this oil-displacing agent need not to add alkali, and is high temperature resistant, and salt resistance ability is strong.
The technical scheme that realizes the object of the invention is: a kind of high reactivity oil-displacing agent, comprise positively charged ion Gemini tensio-active agent, anion surfactant and water, the weight ratio that it is characterized in that described positively charged ion Gemini tensio-active agent and anion surfactant is 1: 5-1: 10, preferred 1: 2-1: 3, the water yield is with cloudy, the cats product gross weight equates, wherein said positively charged ion Gemini tensio-active agent is selected from double hexadecyl dimethyl brometo de amonio, described anion surfactant is selected from the sulfonated alkyl naphathalene formaldehyde condensation products, and described water is tap water or oil field return water.
Wherein the sulfonated alkyl naphathalene formaldehyde condensation products is that refined naphthalene adds a certain amount of formalin under acidic conditions, at 80-100 ℃, under the preferred 85-90 ℃ of condition condensation 3-5 hour, forms in preferred 4 hours.The weight ratio of refined naphthalene and formaldehyde is 2.5: 1.
The high reactivity oil-displacing agent that the present invention uses has active height by composite the forming of cats product of positively charged ion Gemini tensio-active agent and sulfonated alkyl naphathalene formaldehyde condensation products, need not add alkali and can reduce oil/water termination tension force to 10
-3The ultralow state of mN/m.High temperature resistant, not stratified below 180 ℃, do not decompose, anti-high rock salt can anti-total ion concentration be 300000mg/L (Ca wherein
