Annotation:

The authors of the article consider the automatic determination of a sucker-rod deep pump (SRDP) discharge or the flow rate of an oil well based on formation fluid, oil and water. To do this, two pressure sensors are installed at the mouth of the pump-compressor tube (PCT) with a distance of half the length of the cylinder of the used pump. By measuring the pressure drops between these sensors (using a differential pressure manometer) in the calculation and indication block, the value of formation fluid (FF) level is calculated between the sensors in the lower position of the sucker-rod deep pump (SRDP) plunger and the value of the FF flatness and the FF water-flooding in the upper position of the plunger. At the same time, the value of the water and oil density, the dimensions (areas) of the tubing cross-section, the rod and the plunger of the pump are entered manually in the calculation and display block. The proposed method is very simple, allowing accurate and reliable reaching the set goal and does not require additional equipment.
