伴随着我国社会经济的快速发展,我国的油气需求量也大幅增加。在此背景下,利用三次采油技术提升原油的采收率,对缓解我国油田产量下降压力,维持我国原油稳产具有重要的战略意义。本文在分析三次采油驱油机理的基础上,重点分析了以气驱为主的当前几种典型的三次采油技术,并详细阐述了以蒸汽吞吐和注蒸汽为主的稠油开采方法。
With the rapid socio-economic development in our country, the demand for oil and gas in our country has also risen sharply. In this context, the use of tertiary recovery technology to enhance crude oil recovery, to ease the pressure on the decline of oil production in our country to maintain a stable oil production in our country has an important strategic significance. Based on the analysis of the mechanism of tertiary oil recovery and oil displacement, the paper mainly analyzes several typical tertiary oil recovery technologies that are mainly driven by gas flooding and elaborates the heavy oil recovery method that mainly focuses on steam stimulation and steam injection.
