Description
Technical field
The invention belongs to field of fine chemical, be specifically related to a kind of oil recovery surfactant composition and preparation method thereof.
Background technology
Along with the increase of world energy sources demand, the rational exploitation and utilization of oil has caused the very big attention of people, to the produced quantity of oil and the requirement of production efficiency also more and more higher.Realize the high-efficiency mining of hydrocarbon resources, not only there is realistic meaning for raising crude production rate, have more important strategic importance.1/3 of the general only extraction oil in-place of conventional oil production method (once with secondary method), also have an appointment 2/3 crude oil fail extraction, therefore when energy day is becoming tight, improve the key subjects that tar productivity has become oil production research.Tertiary oil recovery technology is then a kind of method of effective raising tar productivity, wherein, chemical flooding is extremely important in intensified oil reduction and the extensive technology implemented, and comprises the multiple combination technology of polymer flooding, surfactant flooding, caustic waterflooding etc. and polymkeric substance, alkali, tensio-active agent.The effect of chemical flooding is the result of physical action and chemical action, and what physical action referred to displacing fluid involves effect, and chemical action refers to the microcosmic oil drive effect of displacing fluid.The core of chemical action reduces the interfacial tension of displacing fluid and crude oil, tensio-active agent is owing to having oleophylic (hydrophobic) and hydrophilic (oleophobic) character concurrently, when tensio-active agent is water-soluble, molecule is mainly distributed on water-oil interface, significantly can reduce oil water interfacial tension.The reduction of oil water interfacial tension means that surfactant system can overcome the force of cohesion between crude oil, larger oil droplet is dispersed into little oil droplet, thus improve the percent of pass of crude stream when pore throat, the oil displacement efficiency of tensio-active agent also shows the effects such as the wettability of rock surface making oleophylic reverses, emulsification of crude oil, raising surface charge density and oil droplet coalescence, and this is the reason that tensio-active agent plays very important effect in chemical flooding technology.
In current tertiary oil recovery research, the kind of tensio-active agent used is maximum with anionic, and conventional has sulfonic acid (sulfuric acid) salt, sulfonated petro-leum, alkylbenzene sulfonate, sulfonated lignin, sulfonated α-olefin, fatty alcohol polyoxyethylene ether sulfate, alkylphenol polyoxyethylene vitriol, aliphatic alcohol polyethenoxy ether carboxylate, alkyl polyoxyethylene polyoxypropylene ether sulfate and alkylphenol-polyethenoxy polyoxypropylene ether sulfate etc.Anion surfactant can be used in various surfactant flooding, wherein applies sulfonate type maximum, and in sulfonate type anion surfactant, the most general with mahogany acid salt form.Sulfonated petro-leum cost is lower, and interfacial activity is high, and heat resistance is good, but saline-alkaline tolerance is poor, and micelle-forming concentration (cmc) is higher, and absorption in the earth formation, viscous flow and the effect with polyvalent ion, result in the loss in oil displacement process.
The requirement of the development Surfactant of tertiary oil recovery technology is more and more higher, not only requires that it has low oil water interfacial tension and low adsorptive value, and requires it and reservoir fluid compatibility and cheapness.In recent years, increasing people starts to pay close attention to surfactant compound system, this is because, suitable surfactant compound system can not only produce good synergistic effect and reduce the interfacial tension of system, and the consumption of primary surfactant can also be reduced, even the total concn of oil driving liquid tensio-active agent also likely reduces, and other performances such as salt resistance ability, heat resistance or the absorption loss minimizing etc. of tensio-active agent are simultaneously strengthened.Therefore by the suitable composite mixing of kinds of surface promoting agent, respective advantage can be made to give full play to, mutually learn from other's strong points to offset one's weaknesses.
Summary of the invention
