Description
Technical field
The present invention relates to a kind of surfactant composition and uses thereof.
Background technology
China's main oilfield is through once with behind the secondary recovery having entered high water-cut stage, crude production rate descends year by year, for improving oil recovery factor, develop remaining reserves to greatest extent, tertiary oil recovery technology is guaranteeing to have brought into play important effect aspect the oilfield stable production high yield.Ternary composite driving (alkali-polymkeric substance-tensio-active agent) technology of wherein using tensio-active agent be owing to still can increase substantially oil displacement efficiency under the situation of low surfactant consumption, so it has become the new technology at economic and technical all very successful raising oil recovery factor.Its dominant mechanism is: after the oil field enters high water-cut stage, surplus oil with discontinuous oil film by trap in the hole of reservoir rocks, two main power that act on the oil droplet are viscaps, if select suitable surfactant system for use, reduce the interfacial tension between profit, make interfacial tension between the oil bearing reservoir profit from the lower or ultralow value (10 of 20～30 milli ox/Mi Jiangzhi
-3～10
-4Milli ox/rice), just can reduce the resistance that the oil droplet distortion was brought when surplus oil was moved, thereby significantly improve oil displacement efficiency.Tensio-active agent improves oil recovery factor and depends mainly on sweep efficiency and the oil displacement efficiency of tensio-active agent in oil reservoir.Promptly
E?r＝Eυ·E?d
In the formula: E r represents recovery ratio, %; E υ represents sweep efficiency, %; E d represents oil displacement efficiency, %.Therefore, improving E r must start with from improving E v and E d.Promoting agent (comprising tensio-active agent and alkali) has effects such as the oil water interfacial tension of reduction, can improve E d (oil displacement efficiency).This effect can be described by combined effect parameter hollow billet number (N):
E?d∝N
N=motivating force/viscous force ∝ μ υ/Y
Ow
In the formula: μ represents to inject phase viscosity; υ represents to inject the phase flow stream velocity; Y
OwInterfacial tension between the expression profit.Practice proves: reduce residual oil saturation effectively, the hollow billet number must be improved 3～4 orders of magnitude.Because oil reservoir injection rate and pressure are limited, it is not enough therefore depending merely on raising μ and υ, but can be with oil water interfacial tension Y
OwReduce by 3 or the higher order of magnitude, thereby improve the hollow billet number greatly and E d (oil displacement efficiency) is significantly improved, this also is the main oil-displacement mechanism of promoting agent.And to improve sweep efficiency, and main way is the mobility that reduces displacing fluid, this point can realize by adding polymkeric substance increase displacing fluid viscosity.Adopt in the operation three, utilization A S P ternary composite driving (tensio-active agent/alkali/polymkeric substance) flooding system, can make the ultra low interfacial tension between profit that the displacement of reservoir oil (E d) rate of imitating is increased by adding tensio-active agent, (E v) injects alkali to reduce the absorption of tensio-active agent to increase injection fluid viscosity raising sweep efficiency by injection of polymer.Make full use of the useful synergistic combination effect of A S P, improve oil recovery factor (E r).
At present, in tertiary oil recovery, the tensio-active agent that generally uses contains the tensio-active agent of phenyl ring as sulfonated petro-leum, alkylbenzene sulfonate or other.Document CN1458219A discloses the pure binary ultra low interfacial tension of the surfactant polymer combination flooding prescription that a kind of tertiary oil recovery is used, use therein tensio-active agent is sulfonated petro-leum or is the complexed surfactant that host adds thinner and other surfactant compound with the sulfonated petro-leum, the weight percent of its component is a sulfonated petro-leum 50～100%, alkylsulfonate 0～50%, carboxylate salt 0～50%, alkylaryl sulphonate 0～35%, low-carbon alcohol 0～20%.These tensio-active agents have the source extensively, and no matter quantity advantage big, that price is low for common oil reservoir, is combination flooding or single surfactant flooding, all has the mass-producing product, are also obtaining ideal effect aspect the raising recovery ratio.But deep day by day along with the oilfield exploitation degree, the oil recovery stratum is more and more darker, and the use temperature of tensio-active agent is more and more higher, the water-mineralizing degree is also more and more higher.The surfactant system of the above successful Application in common oil reservoir (one, two class oil reservoirs), under the high salt of high temperature (formation temperature is greater than 80 ℃) (more than salinity 20000 mg/litre) condition (three class oil reservoirs), because chemical structure malleable, compound system poor stability produce serious chromatographic separation in oil displacement process, cause the oil displacement efficiency variation.In order to reduce oil/water termination tension force to a greater extent, often add the alkali of high density, as sodium hydroxide, yellow soda ash etc.Alkali can generate new tensio-active agent on the spot with the reaction of acidic substance in the crude oil, and adds tensio-active agent and plays synergistic effect.Document CN1439689A discloses a kind of ternary composite oil-displacing system and application thereof of alkali, mixed surfactant and polymer, and the alkali of wherein selecting for use is Na
2CO
3But in use, alkali not only brings huge injury to stratum and oil well etc., and equipment and corrosive pipeline are serious, spends substantial contribution in maintenance, maintenance; And, have to improve greatly the working concentration of polymkeric substance for reaching required viscosity because alkali can seriously reduce the viscosity and the visco-elasticity of polymkeric substance, the oil recovery comprehensive cost is improved.
Summary of the invention
One of technical problem to be solved by this invention is that the composition that contains tensio-active agent in the prior art exists under the high temperature and high salt condition oil displacement efficiency poor, simultaneously owing to contain alkali, injury is brought on stratum and oil well, etching apparatus and pipeline, the problem that production cost is high provides a kind of new surfactant composition.This surfactant composition still can form 10 with crude oil under alkali-free, high temperature and high salt condition
