كيف تُحسب

  • TDH = net lift (dynamic fluid level) + tubing friction head + discharge pressure expressed as head.
  • Friction uses the Darcy friction factor from a Colebrook–White solution, not a nomograph — so viscosity and roughness actually move the answer.
  • Stages = TDH / head per stage from the pump catalogue curve at your rate; shaft power = stages × power per stage × specific gravity.
  • Pump intake pressure = casing pressure + fluid gradient × submergence.

المعايير التي تتحدثها

أين تتوقف عن الصحة

Single-phase liquid only. Free gas at the intake is what actually limits most ESP installations, and it is not modelled here — below the bubble point the developed head collapses in a way no head-per-stage figure from a water curve will tell you. The head and power per stage are also water-curve values; a viscous crude degrades both, and above roughly 100 cp the correction is large enough that a catalogue curve is no longer usable without it.
