三元复合驱油是国外80年代初出现的化学采油新方法，国内于90年代初才开始这方面的研究工作。由于它能较大幅度地提高原油采收率，所以受到采油界的普遍重视，拟列为国家“九五”重点科技攻关计划。本文在简单介绍三元复合驱油提高原油采收率技术的同时，重；或指出了该技术的研究和应用将给地面采出系统可能带来的问题，提出了这些问题的研究思路。 ASP flooding is a new method of chemical production in foreign countries in the early 1980s. Only in the early 1990s did the research on this field begin. As it can greatly enhance the oil recovery rate, it is generally valued by the oil extraction community and is intended to be listed as a key scientific and technological tackling plan of the Ninth Five-year Plan by the state. In this paper, we briefly introduce the technology of ASP flooding to improve oil recovery, meanwhile, point out that the research and application of this technology will bring some problems to the ground recovery system, and put forward the research ideas of these problems.
