摘要

对于许多处于二次采油和三次采油阶段的轻质油油藏,注入空气具有多种提高采收率机理和作用,尤其是深部油藏,可获得独特的经济技术效果。本文介绍有关注空气的室内试验、数值模拟及现场应用与先导试验设计,同时探讨这种工艺方法在提高采收率方面的效果。

Abstract

Air injection has many mechanisms and functions of enhancing oil recovery for light oil reservoirs that are in development phase of secondary or tertiary oil recovery.Especially for deeper oil reservoir,economical and technological effectiveness will be obtained in use of air injection.This paper gives an introduction on indoor testing,numerical simulation,field application and pilot test design of air injection,and discusses its effectiveness in enhancing oil recovery.
