AI Technical Summary
Existing single-channel or dual-channel polymer injection equipment is insufficient to meet the differentiated injection needs of various formation regions in complex oilfield formations, and cannot simultaneously adapt to the pressure and flow requirements of different formation regions.
A three-channel polymer injection booster for oilfields was designed, comprising a power input unit, a booster transmission mechanism, multiple booster cylinders, a control component, and a PLC controller. By using differentiated fan speeds and delivery channels, it achieves precise distribution of polymer solution and adapts to injection parameters of different formations.
It achieves precise distribution of polymer solutions, adapts to permeability differences in complex formations, improves oil displacement effect, reduces maintenance costs, adapts to field environments, operates stably and reliably, and improves production efficiency.
