摘要:

有效渗透率是影响低渗透油藏开发决策的关键参数之一,其获取方法通常会受到连续生产或测试精度等因素的制约。 针对上述问题,基于等效渗流阻力原理,将达西公式和泊稷叶公式相结合,考虑低渗透储层岩石孔喉壁面水膜的影响,并引入有效孔喉半径的概念,建立了低渗透储层岩石有效渗透率计算新模型。 经敏感性分析可知,在低渗透油藏中,孔喉半径与水膜厚度处于同一数量级,水膜对低渗透储层岩石的有效渗透率具有较大影响。 利用新模型计算了南海珠江口盆地文昌 13-1 油田 A4H1 井主力油组的有效渗透率,与试井解释结果基本一致,说明考虑水膜影响的有效渗透率计算新模型能够为低渗透油藏产能评价和动态分析提供可靠的依据,具有良好的应用前景。

Abstract:

Effective permeability is one of the key parameters affecting low permeability reservoir development. Its methods are usually influenced by production or test precision, and generally require a specific set of processes. To solve this problem, a research is made on how to calculate effective permeability by use of the easily obtained data. Accordingly, based on the principle of equivalent flow resistance, combined Darcy formula with Poiseuille formula, a new calculation model for calculating effective permeability in low permeability reservoir was established by considering water film and introducing the concept of the effective pore throat radius. The effective pore throat radius is the difference value between the original pore throat radius and the water film thickness. The sensitivity analysis shows that the pore throat radius has the same order of magnitude with water film thickness in low permeability reservoirs.Therefore, the water film has a great impact on the effective permeability. This new model was used to calculate the permeability of A4H1 well in Wenchang 13-1 oilfield in the Pearl River Mouth Basin, the South China Sea. The permeability calculated by the new model is similar to the result of well test analysis. It is shown that the new model is reliable and can provide foundation for productivity evaluation and dynamic analysis in low permeability reservoir,and it has a favorable application prospect.
