碱和合成的表面活性剂二元复合驱（AS）是一项带有方向性的廉价的提高采收率技术。在碱和表面活性剂的水相混合体系中再加入聚合物形成碱-表面活性剂-聚合物三元复合驱（ASP）可以进一步提高石油采收率。原油中的酸性物质与三元体系中的碱中和，在油水界面形成活性物质，降低油水界面张力（IFT）。本文所描述的三元复合驱和微生物技术的结合方法对单独三元复合驱不能起作用的原油应用该项技术是一项经济有效的创新技术。这项技术是基于微生物可以改变原油；产生酸性物质如羧酸，并在油水界面上被碱混合物中和。应用氧化烃类微生物；比如节杆菌（arthrobacter.sp），在实验室摇瓶论验中发现原油样品中酸含量增加。测量微生物处理过的原油和碱／表面活性剂混合物之间的悬滴界面张力低于没有利用微生物处理原油的值。对于用节杆菌处理过的原油；界面张力从0.327mN／m（未处理）降到0.07333mN／m。为了优化该项技术，筛选了多种微生物。并开展了岩心驱替实验，定量确定原油采收率。应用微生物驱和三元复合驱技术进行的实验室岩心驱油实验表明，微生物驱和三元复合驱结合技术的原油采收率比单独微生物驱和单独三元复合驱的都高。经微生物预处理的采油方法，原油采收率的提高值与微生物处理的原理酸含量的增加
Bases and Synthetic Surfactants Binary compound flooding (AS) is an inexpensive and directed oil recovery technique. The addition of polymer to form an alkali-surfactant-polymer ASP in an aqueous system of alkali and surfactant can further increase oil recovery. The acid in the crude oil is neutralized with the base in the ternary system, forming an active substance at the oil-water interface, reducing the oil-water interfacial tension (IFT). The combination of ASP flooding and microbial technology described in this article is a cost-effective and innovative technology for the application of crude oil that is not effective with a single ASP flooding. The technology is based on the fact that microorganisms can alter crude oil; produce acidic species such as carboxylic acids and are neutralized by an alkaline mixture at the oil-water interface. The use of oxidized hydrocarbon microorganisms; such as arthrobacter. Sp, has been found to increase the acid content of crude oil samples in laboratory shake flask experiments. The measured hanging drop interfacial tension between the microbiologically treated crude oil and the base / surfactant mixture is lower than the value of the non-microbiologically treated crude oil. For the crude treated with Arthrobacter; the interfacial tension dropped from 0.327 mN / m (untreated) to 0.07333 mN / m. In order to optimize the technology, a variety of microorganisms were screened. A core flood experiment was carried out to quantitatively determine the crude oil recovery. Laboratory core flooding experiments using microbial flooding and ASP flooding technology show that the recovery rates of crude oil from microbial flooding and ASP flooding are both higher than that of microbial flooding and ASP flooding alone. Microbial pretreatment of oil recovery methods, the increase of crude oil recovery and the principle of microbial treatment increased acid content
