Abstract: Based on energy and mass conservation law, the calculating mathematical models about ESP high efficiency operating were established. The "FTZ1 air bleed adjustable bean" was taken as a technical method to adjust the operating point of the ESP well. The high efficiency operating point were scouted and the corresponding computer program were worked out by the method of "interval division and roll along approximation". Comparing the measured data of two wells with the predicting values by computer program, we find that the high efficiency operating program of the ESP has a high precision. The ESP can work in high efficiency region by using the calculating results to adjust the swab parameters, and the effect of saving energy is remarkable.
