Water cut monitoring system.

摘要

Fluid from a producing well is accumulated in an accumulator (10) and allowed to separate into free water, a water-continuous phase and an oil-continuous phase; the separated fluid flows through a monitor (30) having electrodes (104-106;152-157) exposed to the fluid; a power source (125) provides an AC voltage and current to the electrodes and provides an injection voltage signal (Vi) and an injection current signal (Ii); a generator (125) provides a phase angle signal (PH), a sensor connected to another said electrode provides a sensed voltage signal (VS), and a sensor provides a temperature signal (T); and a processor (22) provides a water content signal (WC) in accordance with signals Vi,Ii,PH,VS and T and depending on whether the fluid is in the water-continuous or in the oil-continuous phase. <IMAGE>
