摘要: 综合应用流体力学、渗流力学、输砂力学和流体热力学等理论,分析支撑剂在三维裂缝中的运移分布规律,建立了一会考虑缝高变化时支撑剂运移分布的数值计算模型,并利用该模型进行了实例计算。该模型和方法能满足三维压裂设计的工程计算需要。Abstract: Migration and distribution patterns of proppant in 3-D fractures are analyzed through comprehensive application of several theories including fluid mechanics, seepage flow mechanics, sand-transportation mechanics and fluid thermal-dynamics. A numerical model with variable fracture height is set up and used in practical calculation. This model and method can meet the needs of engineering calculation of 3-D fracture design.
