摘要

驱技术在国外应用广泛

而国内应用规模相对较小

重要因素是其技术和经济指标备受考验。以近年苏北小断块油藏CO

驱项目为例

分析了CO

吞吐、低渗油藏同步气驱、气顶驱、气水交替、中高渗油藏CO

复合驱等开发模式

及其经济效益与影响因素。苏北实践表明CO

驱项目经济效益与注入成本和换油率密切相关

各开发模式经济效益有一定差异但总体较好

特别是低渗低含水油藏通过气顶驱及气水交替驱效果较佳。

Abstract

-EOR has been widely used in foreign countries

but rare in China because of technical and economic factors. Taking the CO

flooding project of the small fault block reservoir in Subei basin as an example

the development modes of huff-n-puff

synchronous gas injection

gas cap flooding

gas-water alternation

combined flooding in medium and high permeability reservoirs are summarized

and economic benefits and influencing factors are analyzed. The practice in Subei basin shows that the economic benefits of CO

flooding projects are closely related to the injection cost and utilization of CO

. The economic benefits of various development models are different but overall are good

which play a better performance in l

ow permeability and low water cut oil reservoirs through gas cap flooding and gas-water alternate flooding.
