摘要
分析了注气驱油条件下，气液两相之间的相互关系，以及气驱对消除毛管力、降低界面张力的作用。论述了注入气与原油的化学组份决定气液混相方式的机理。借鉴国外矿场应用的经验，从影响因素入手，研究了注气开发的基本条件，其中包括：油藏地质结构、油层特征参数、油藏流体性质、油层压力及气源等。
To analyse the relation between gas and liquid, and the effect on eliminating capillary power and decreasing interface power in natural gas flooding, and to discuss the miscible mechanism decided by the composition of injection gas and crude oil. Using the experience of other countries for reference, the basic conditions of natural gas flooding are studied, including the geological structure of reserviors, reservoir characteristic parameters, fluid quality, reservoir pressure and natural gas sources. The theoretical basis is provided for feasibility studying of natural gas flooding.
