复合油藏的数学模型在试井分析中得到了广泛的应用。在采油过程中，由于驱替剂的注入或置换，模型边界会发生移动。目前，动边界复合油藏的数学模型研究较少，不能满足工业需要。本文建立了考虑井筒储存和表皮效应的复合油藏动边界数学模型。研究了动边界复合油藏的压力瞬变特征，分析了初始边界半径、动边界速度、表皮系数、井筒储存系数、扩散系数比、流度比等参数对压力和产量的影响。动边界效应主要表现在生产中后期。该模型为这类油藏的试井分析提供了新的理论基础。
The mathematical model of composite reservoir has been widely used in well test analysis. In the process of oil recovery, due to the injection or replacement of the displacement agent, the model boundary can be moved. At present, the mathematical model of a composite reservoir with a moving boundary is less frequently studied and cannot meet industrial demand. In this paper, a mathematical model of a composite reservoir with a moving boundary is developed, with consideration of wellbore storage and skin effects. The characteristics of pressure transient in moving boundary composite reservoir are studied, and the influences of parameters, such as initial boundary radius, moving boundary velocity, skin factor, wellbore storage coefficient, diffusion coefficient ratio, and mobility ratio on pressure and production, are analyzed. The moving boundary effects are noticeable mainly in the middle and late production stages. The proposed model provides a novel theoretical basis for well test analysis in these types of reservoirs.
