High water content is a critical issue that must be urgently addressed in the current oilfield development, and single-well injection-production technology (SWIPT) an effective approach for achieving economical extraction high-water-content oilfields. To meet 5.5-inch casing size requirements, further improve SWIPT performance, minimize impact of pump pressurization on subsequent oil–water separation process, dual-pump suction-SWIPT proposed axial-flow cyclone pipe string designed. A theoretical fluid–solid interaction (FSI) model downhole (DHPS) applicable to established through vibration testing data analysis. Based new FSI model-corrected numerical simulation method, single-factor experiments are performed analyze medium transport process performance within flow field under structural disturbances. The results indicate fluid media DHPS not significantly affected by interference. closely matched experimental data, with average error axial velocity at different test points being 0.041 m/s. In regions, minor variations pressure fields observed conditions. Under inlet rate 4 m3/h, split ratio 30%, oil volume fraction 1%, optimal efficiency 97.26% achieved. This study provides insights development application SWIPT.
