摘要:

注空气提高原油采收率技术已经在国外多种油藏和各种地质条件下得到了成功应用,其特点是操作成本低、注入能力强、驱油效率高、储量动用程度大。系统介绍了国外注空气开发稀油油藏、稠油油藏、沥青质油藏的成功实例以及我国油藏注空气开发的技术现状,分析了注空气技术的机理、提高采收率效果及成功应用的关键因素,对我国各类适合注空气的油藏开发调整具有一定借鉴意义。

关键词: 注空气, 提高采收率, 驱油效率, 油藏, 储量动用程度

Abstract:

Air injection for enhanced oil recovery has been successfully applied in various overseas reservoirs and geological settings, it has the advantages of low operation cost, high injectivity, high oil displacement efficiency and reserve tapping efficiency. In this paper, successful overseas air injection projects including light oil reservoirs, heavy oil reservoirs and bitumen reservoirs are systematically presented; current status of air injection technology in domestic reservoirs is briefly introduced; the mechanism of the technology, effect of enhanced oil recovery and the key factors of successful implementation are discussed, which can be used as a reference for the development of various domestic reservoirs.

Key words: air injection, EOR, oil displacement efficiency, reservoir, reserve tapping efficiency
