摘要
针对三元复合驱分注过程中低视粘度损失和高压降不能同时实现的问题,设计出了一种新型降压槽,运用CFD软件对其环空流道的流动特性进行数值模拟,研究了新型降压槽内的压力、速度、湍动能、视粘度和应变率分布情况.同时将其与环形降压槽进行对比,结果表明,相同长度的降压槽,新型降压槽的压差更大,视粘度损失更小.
Aiming at the problem of low apparent viscosity loss and high pressure drop can not be achieved simultaneously in the separate injection process of ASP flooding, a new depressurization slot was designed, the CFD software was used to simulate flow characteristics of its annular channel, the distribution of pressure, velocity, turbulent kinetic energy, apparent viscosity and strain rate were studied. At the same time, it was compared with the annular depressurization slot, and the results showed that the pressure drop of the new depressurization slot is greater than that of annular depressurization slot and the apparent viscosity of the new depressurization slot is smaller than that of annular depressurization slot.
