Water Injection Station Design Based on One-For-Several Rotor VVVF Technique

Abstract:

In the process of oilfield water injection volume of injection allocation often appears with the pump displacement situation does not match; the widespread adoption of stator frequency technology allows the pump displacement and volume of injection allocation phase matching. But the technology in pump class load application speed range is limited, there is still a reflux valve control blind area," turn off undead" problem. One-for-several" rotor frequency Technique in water injection station application solved the control blind area problem, the full realization of the variable frequency close return voltage injection, at the same time, the successful implementation of the slip power efficient feedback. Stable water injection pressure of the system and the electric energy is saved, satisfy the oilfield high efficiency, fine water needs, has a high application value.
