注CO_2驱油技术的室内评价方法及应用概况

Research on evaluation methodologies of carbon dioxide flooding technology and current applications

注CO_2驱油作为一种有效提高采收率的方法,在油气田开采中已经占据越来越重要的地位。阐述了CO_2驱油机理、及其对应的驱油方式。其中比较系统的总结出了现行测定及评价注CO_2驱参数的各种室内试验方法并调研了CO_2驱油技术的国外概况和国内应用现状,提出在气源上,建议有关油田与工厂合作,合理的利用工业废气,开展CO_2捕集和驱油埋存先导性研究。

Carbon dioxide flooding is an effective way of EOR,and it＇s playing a more and more important role in recovering oil and gas.This paper states the mechanism of carbon dioxide flooding,gives a presentation of its driving methods correspondingly,highlights in summing up the ways that test and evaluate parameters of carbon dioxide flooding inside laboratory currently surveys the carbon dioxide flooding technology application situation domestic and abroad suggests oilfield to cooperate with surrounding factories to get enough gas resources,makes a rational use of industrial waste gas and studies on CO_2 capturing and pilot tests of buried flooding.
