提高采收率的注气实验评价体系

注气与常规的水驱及其它驱动方式相比有较大的特殊性，近年来由于各种气源的大量发现，越来越多的油田开发探索注气提高采收率的可行性问题，然而目前还未见到系统评价，配套实验及在开发中的应用方面的文献，根据多年研究的经验和国内外相关的报道，首先对注气相关配套实验及研究目的进行简要介绍，然后对不同种类的油田和注入介质的实验内容进行分析，为现场注气，室内评价实验内容的设置及研究提供参考。

Evaluation System of Gas Injection Experiment for EOR

There are big differences between gas injection and water flooding or other displacement process.In re-cent years,with discovery of more and more natural gas or gas shows,more and more oilfields have started to probe fea sibilities of using gas injection for EOR.However,few literatures about systematic evaluation and related exploration that are applied for oilfield development are published at present.According to many-year studying experiences and re-lated re ports at home and abroad,this paper briefly presents the purposes of gas injection experiment and relevant re-searches,followed by making analysis of various lab contents in different oilfields and injected media.These can be as a guide for considerations of lab experiment contents and research projects as required for field gas injection project plan-ning and evaluation.
