三元复合驱小尺寸压力调节器的结构优化

Structure Optimization of ASP Flooding Small Size Pressure Regulator

在同样的配注量和其他工况条件下,不同的压力调节器中流体的过流特性有所差异,包括三元液黏度损失率、压降等参数。但较高的压降与较低的黏度损失率不能同时存在,两者之间存在矛盾。通过对压力调节器模型进行CFD解析,得到了ASP流体流经不同尺寸的压力调节器模型的速度分布、压力分布、表观黏度分布等。通过分析,优选出槽距为7 mm,坡角为20°,半径差为1mm,槽深1.82mm的压力调节器。ASP流体流经该尺寸压力调节器,黏损率较小且压力调节器两端压降满足现场工作条件,较适合工作现场应用。

In the same conditions with fluence,and other conditions,reflected by the fluid pressure controller,over-current characteristics differ,including the parameters of the polymer viscosity loss rate,the pressure drop.High pressure drop and the low viscosity of the loss rate can not exist together.In this paper,the CFD analysis on the pressure controller models,the ASP flooding flows different pressure controller model velocity distribution,pressure distribution,the viscosity distribution were obtained,through the analysis in this paper,the optimization is the slot pitch of7 mm,the slope angle of 20°,the radius difference of 1mm,the groove depth of 1.820 mm pressure regulator.The ASP flooding flows through this size of pressure regulator,the rate of viscosity loss is small and the voltage drop across the pressure regulator meet on-site working conditions,more suitable for the job site applications.
