气驱过程中气窜问题的室内研究与探讨

气驱实验是注气提高采收率研究的基础,物理模拟实验过程中气窜问题是影响气驱实验研究的重要因素之一,如何有效预防气窜和发生气窜后采取正确的处理手段对气驱室内研究尤其重要。文中较为系统地分析了气窜问题带来的危害,从机理研究和现场应用相结合的方法入手,对气窜压力的测定、影响因素、防气窜机理和防气窜方法进行了深入的研究,并结合室内现有条件对气窜问题进行系统的分析与探讨,论述了如何对气驱室内研究过程中气窜的问题进行控制,并提出合理的意见和建议。

Laboratory study on the problem of gas channeling during gas flooding

Experiment study of gas flooding is one of the basic researches of enhancing oil recovery （ EOR ） . The channeling problem of gas flooding during physical simulation experiment process is the key that affects gas drive experiment. How to prevent gas channeling effectively and to take right measures when gas channeling occurred is particularly important for indoor study of gas flooding experiment. The gas channeling damages were analyzed by combining the mechanism and field application. The pressure of gas channeling, influence factors, anti-gas chan-neling mechanism and the preventing measures were also discussed. Furthermore, by combining existing indoor con-ditions, the gas channeling was analyzed and discussed, how to deal with gas drive indoor research, and sugges-tions about the control over gas channel were put forward.
