Abstract
The invention discloses a preparation method and application of fatty amide polyethylene polyamine amino acid for tertiary oil recovery. The method comprises the following steps of: synthesizing a fatty amide polyethylene polyamine intermediate; and synthesizing the fatty amide polyethylene polyamine amino acid. The fatty amide polyethylene polyamine amino acid surfactant prepared by the method is suitable for the tertiary oil recovery in the oil field, serves as an oil displacement agent to prepare a binary composite oil displacement system, has excellent interfacial tension, emulsification and oil displacement performance, and is compatible with different oil-water conditions to achieve the perfect oil displacement effect.
Description
Technical field:
The present invention relates to a kind of amino acid whose preparation method of used for tertiary oil recovery fatty amide polyethylene polyamine and application thereof.
Background technology:
Tensio-active agent is used for tertiary oil recovery and mainly contains single surfactant flooding, binary combination flooding, ternary composite driving.Wherein ternary composite driving (alkali+polymkeric substance+tensio-active agent) is a kind of method that improves recovery ratio that last century, the eighties grew up, this flooding system can reduce oil water interfacial tension, reduced and used the remaining resistance that the oil droplet distortion brings when mobile, thereby improved oil displacement efficiency.Yet, because the alkali (sodium hydroxide) in the ternary composite displacement system has solvency action to rock in the stratum and mineral, cause the fouling of joint station treatment system serious, influenced the normal operation of crude production.The existence of alkali can cause the down-hole fouling, even the decline of production fluid amount occurs, and problems such as recovery well holddown also can cause the oil reservoir clay dispersion, and migration and expansion cause reservoir permeability to descend, and reservoir is damaged, and have a strong impact on field produces.Contain the injury that the alkali compound system causes oil reservoir for alleviating, the general method that adopts reduction alkali consumption or use weak base to come synergistic surfactant generation ultra low interfacial tension, but weak base can produce serious injury to the stratum too.
Current in order to strengthen the oil displacement efficiency of tensio-active agent, often adopt the compound system of mixed surfactant to carry out the displacement of reservoir oil.But when this system is passed through pore media, because of the difference of its adsorptive power and in difference oily, that aqueous phase distributes chromatographic separation takes place.
