摘要
根据低渗油藏的特点,建立了圆形封闭地层中心一口井的低渗非达西渗流数学模型,通过块中心网格和隐式差分格式对数学模型进行离散化求出数值解,并用该模型对塔里木油田塔中58C井进行了解释。结果表明,该模型可以较好的模拟井底的压力变化。
According to the characteristics of low permeability reservoir,a Mathematical model of low permeability and non-Darcy flow in Circular and closed reservoirs is built.Through block-centered grid and implicit difference method,disserting Partial Differential Equation and obtain numerical solutions is studied.By this method Well TZ58C is interpreted in Tarim Oilfield,the results can better reflect the changes of bottom well pressure.
