摘要
哈特曼流体声波发生器是广泛应用于油田解堵施工的物理法解堵设备。系统介绍了哈特曼声波发生器的发声和解堵机理,并推导了考虑流固耦合作用下的波动方程来描述声波在多孔介质中的传播特性,以确定不同物性参数的声波在地层的传播深度;考虑了流体粘度、地层渗透率、声波频率、渗流速度等因素对声波衰减的影响,以确定解堵深度来指导现场施工。
Hartmann acoustic wave generator is widely used physical equipment in reservoir breakdown performance. The wave-generation and reservoir break-down mechanism are illustrated. To calculate the effective depth, an improved wave equation is also got, considering the coupling of liquid and reservoir. Factors such as liquid viscosity, permeability, acoustic frequency and seepage flow speed influencing the effective rang are also accounted to improve the method for deter mining the effective break-down depth as guidance during the performance.
