| 摘 要： | 以油层物理理论、渗流力学原理和油气藏工程方法等基础理论为指导,提出了低速层流条件下储层中描述大孔道的数学模型,推导出了注水开发过程中五点法注采井网下不同位置大孔道变化规律的关系式。并举例说明了在实际中如何应用这个数学模型进行模拟。模拟结果表明,该模拟模型能很好地模拟大孔道的变化规律。这为这一领域的深入研究提供了理论基础。

| Abstract: | A general mathematical model is established to describe the formation of water channel in unconsolidated reservoir under low velocity laminar flow condition by using theories of Petrophysics and Reservoir Engineering.Then,a more specific mathematical formula is derived for five-spot pattern,the formula can simulate the changing of water channel size at different locations of the reservoir during water flooding process.Next,an example is given in the paper to demonstrate how to use this model practically,and... |
