摘要(Abstract)：

本文运用简化二维三相数学模型,结合正韵律厚油层地质特征,对影响水气交替注入效果的地质条件、完井方式、注入方式、注入速度、注采井距等相关因素进行了数值模拟研究。指出了大庆油田正韵律厚油层通过水气交替注入是可以提高最终采收率的,并给出了为提高注气效果而应采取的各项措施。
Taking into account of the geological characteristics of the normal rhythmic thick formation, a simplified 2 D-3 P mathematical model is used to simulate the related factors such as geological conditions, completion types, injection pattern, injection rate, spacing between injection and production wells etc. which affect the results of alternatively water-gas injection. The results indicate that ultimate recovery can be raised by alternatively water-gas injection in a normal rhythmic thick formation in Daqing Oil Field and in the paper, several measures that should be taken in order to improve the results of gas injection are suggested.
