注蒸汽采油方法是提高原油采收率的有效手段之一,我国蒸汽驱油和蒸汽吞吐技术已相对成熟,取得了较大发展。本文概述了注蒸汽采油主要方法,从基础理论研究、室内实验研究、现场试验及推广应用等方面对我国近年来注蒸汽采油研究现状进行综述,提出在进一步的研究中,要重视降低蒸汽成本、改善注入环境污染等问题。 Steam injection method is one of the effective ways to improve the recovery rate of crude oil. China’s steam flooding and steam huff and puff technology are relatively mature and have achieved great development. This paper summarizes the main methods of steam injection, summarizes the research status of steam injection in recent years in China from basic theoretical research, laboratory experiment research, field test and popularization and application, and puts forward that in the further research, we should pay attention to reducing the steam cost, Improve the injection of environmental pollution and other issues.
