摘要
在油藏中注入各类气体示踪剂,来了解注入流体和被驱替流体在储层多孔介质中的运移特征的示踪剂方法是注气油藏开发动态监测的重要手段之一。在对国内外有关气体示踪剂文献调研的基础上,将水示踪剂的分配机理运用于注气油藏中气体示踪剂在油藏流体中的分配及其影响因素研究、滞留机理,运用多元回归分析方法回归处理滞留实验的结果,并初次引入概率理论来描述气体示踪剂在油藏多孔介质中的运移特征,建立起气体示踪剂在油藏多孔介质中运移的特征速度方程。
Abstract
The way of researching into the injected and the dispersed liquid's flow characteristic in the reservoir of porous medium by injecting some gas tracers has been proved to be an efficient method. Based on the research of many literatures about gas tracer, the principle of gas tracer's distribution, retention and the factors of impaction in the reservoir of porous medium was studied, the theory of pluralistic regression was applied to deal with the retention experiment, and the theory of probability to analyse the gas tracer's movement character was introduced as well. Then the characteristics speed equation of gas tracer in the reservoir of porous medium was established.
