基于t模型对广义水驱曲线的系统化分析

Systematic analysis on generalized water flooding curve based on t model

针对以往在广义水驱曲线分析中杂乱零散的缺陷,通过引进t模型构建一个能使该分析系统化的基础框架。在定性描述t模型应用于水驱曲线分析的可行性的基础上,运用数学方法分析了参数k、n对模型性质的影响,揭示出t模型与水驱曲线之间的耦合关系。把讨论结果与广义水驱曲线的定义相结合,将t模型作为水驱曲线系统化分析的理论框架,从一个全新的角度推导出一系列包括两种比较经典类型的广义水驱特征曲线,从而达到了系统化分析的目的。

Since existing generalized water flooding curve analysis has disadvantage of being cluttered and scattered, this paper introduces t model to construct a basic framework which can make the analysis systematic. Based on qualitatively illustrating the feasibility of t model applied in water flooding curve analysis, this paper uses mathematical method to analyze the effect of parameters k and n on mode] property, and gives coupling relation between t model and water flooding curve. The paper combines discussion result and generalized water flooding curve definition, takes t model as theoretical framework for systematic analysis on water flooding curve, and derives a series of two typical types of generalized water flooding characteristics curve in a new point of view.
