摘要：
In order to solve the problem of the complicated process of downhole oil-water separation hydrocyclones connection in parallel, a new structure of multi-stage spiral separator is proposed based on the principle of tandem hydrocyclone separation. Response surface method combined with computational fluid dynamics is used to build a mathematical relationship model between the structural parameters and the separation efficiency of a multi-stage spiral separator, resulting in an optimal structural parameter, and systematically explored the optimal structural model within a certain range. The separation performance changes corresponding to different inlet flow rates, oil phase volume fractions and split ratios. Indoor separation performance experiments are conducted to verify the accuracy of numerical simulation results and the efficiency of optimization results. The results showed that the optimized structure could increase the separation efficiency from 91.0% to 96.2%. Comparison of separation performance at different inlet flow rates, the optimal inlet flow rate of 2.5 m3/h was obtained; within a certain range, with the increase of oil phase volume fraction and overflow split ratio, the separation efficiency showed a tendency of increasing and then decreasing, of which the simulated efficiency could reach up to 99.72%, and the experimental efficiency could reach up to 97.70%, which further verified the reliability of the simulation results and the efficiency of optimization results. © 2023 Chemical Industry Press.
