摘要
CO_2驱油技术是目前用于提高原油采收率的关键的技术之一,也是CO_2资源化利用降低排放量的有效手段。随着美国、加拿大等国的CO_2驱油项目大获成功,我国在该技术领域的研究投入也越来越大。然而我国陆相沉积的特殊性决定了油藏条件较国外不同,我国低渗透储量巨大,如何在低渗透油藏中成功应用CO_2驱油技术是关键所在。本文围绕CO_2驱油技术的驱油机理、油藏筛选标准、室内研究及低渗透油藏的CO_2注入方式等方面取得的最新进展进行了评述,指出了目前CO2驱油技术存在的问题,并对这些问题的处理方法进行了探讨。
The CO 2 flooding is one of the critical technologies currently used to enhance oil recovery,and it is also an effective means to reduce the emission of CO2.With the success of CO2 flooding projects in the United States,Canada and other countries,China s research investment is increasing in this area.However,the special continental deposition in China determines that the reservoir conditions are different from other countries.Our country s oil and gas reserves in low permeability reservoirs are huge,how to successfully apply CO2 flooding technology in low-permeability reservoirs is critical.This article reviewed the latest advances in CO2 flooding technology,such as CO2 flooding mechanism,reservoir screening standard,laboratory test and CO2 injection in low permeability reservoirs,we pointed out the current issues CO2 flooding technology,and also discussed solution of these issues.
