摘　　要：三次采油技术是建立在注水保持油层压力的基础上,依靠注入大量新的驱油剂来改变流体的黏度、组分和相态的物理化学特性,从而提高原油采收率的驱油方法,而阴离子表面活性剂凭借其廉价易合成的特点,作为新的驱油剂被广泛地运用在三次采油领域。本文重点阐述了在三次采油领域中典型阴离子表面活性剂的主要类型及其特点,为今后开发新型阴离子驱油剂提供一些研发思路。Tertiary oil recovery technology is a displacement method established on the basis of maintaining reservoir pressure through water injection,which relies on injecting a large amount of new displacement agents to change the physical and chemical properties of fluid viscosity,components,and phase states,thereby improving crude oil recovery.Anionic surfactant,due to their cheap and easy to synthesize characteristics,are widely used as new displacement agents in the field of tertiary oil recovery.This article focuses on the main types and characteristics of typical anionic surfactant in the field of tertiary oil recovery,providing some research and development ideas for the future development of new anionic oil displacement agents.
