Design and Analysis of an Axial Center-Piercing Hydrocyclone

To enhance the separation efficiency of downhole oil–water hydrocyclones in co-produced wells, an axial center-piercing hydrocyclone structure is proposed. A mathematical relationship model between structural parameters and constructed based on response surface methodology. The numerical simulation method employed to analyze both unoptimized optimized structures, their performances are simulated under identical operational conditions. results indicate that optimal parameter values as follows: main diameter D = 70.4 mm, large cone angle α1 32.4°, small α2 3.9°, bottom flow tube length L3 311.7 inverted L4 166.0 mm. operation also obtained. Under same operating conditions, consistently higher than structure. highest achieved by 98.6%, which a 2% improvement over state. Finally, experiments conducted with separator different split ratios. This study significantly contributes field injection production single well, particularly promoting application hydrocyclones.
