摘要
数值流线法是在20世纪90年代发展起来的一项较新的数值模拟技术,它在油藏模拟中的应用越来越广泛,其应用领域也在不断扩大。本文从双孔单渗的渗流理论出发,建立双孔单渗数学模型,并应用飞行时间变量将其转换为流线格式的双孔单渗流线模型。根据所建立的流线模型,利用数值流线法模拟的方法,编制了计算程序,计算结果符合实际裂缝性油藏的生产特征。
Streamline - based simulation method is a new reservoir numerical simulation technology that has been developed since 1990s. In recent years, it has been more and more widely applied in reservoir modeling and its application fields are also continuously enlarging. Based on dual - porosity and single - permeability filtration theory, a dual - porosity and single - permeability mathematical model is built and transformed into a streamline - based dual - porosity and single - permeability model by using time of flight. Based on the streamline model built, a calculation program is developed by using streamline - based numerical simulation method. The calculation results accord with the practical production characteristics of fractured reservoirs.
