摘要：
Based on numerical simulation method and central composite design method, the mathematical models of the relationship among the structural parameters of downhole hydrocyclones and the separation efficiency and the underflow pressure loss were established by using the second-order polynomial function. Additional tests were carried out to compare the predicted values of the mathematical model with the actual ones of numerical simulation. The average relative errors between the predicted values and the actual ones of the separation efficiency and pressure loss are as 0.104% and 4.562% respectively, which verifies the accuracy of the prediction results of the model. Meanwhile, a comparative study was carried out on the separation performance between the response surface optimization structure and the initial structure. The results show that when the inlet oil droplet size varies in the range of 50~500 μm, the initial structural separation efficiency ranges from 58.92% to 98.56%. After optimization, the separation efficiency ranges from 60.35% to 99.48%. When the inlet water content changes in the range of 94%~99%, the separation efficiency of initial hydrocyclones increases from 74.61% to 88.07%, after optimization the separation efficiency is in the range of 75.26%~91.56%. Under the conditions of different inlet oil droplet size and water content, the optimized structure shows obvious high efficiency and applicability. © 2021, China Mechanical Engineering Magazine Office.
