METHOD FOR DETERMINING VOLUME OF CONSUMED LIQUID Russian patent published in 2015 - IPC G01F1/90 G01F13/00 E21B47/10 

FIELD: oil and gas industry.

SUBSTANCE: method for determining volume of consumed liquid at pumping from a grouting tank to a delivery line of a pump involves measurement of the number of revolutions of a drive shaft of the pump. From the moment of liquid pumping to the delivery line there additionally measured in the grouting tank is drop in its level in the range sufficient for calculation of a conversion coefficient of the number of revolutions of the drive shaft of the pump to volume of consumed liquid. The current value of volume of consumed liquid is determined depending on surface area of liquid in the tank, drop in level of liquid in the tank, conversion coefficient of the number of revolutions of the drive shaft of the pump to volume of consumed liquid, the number of revolutions of the drive shaft of the pump, which is measured from the moment of completion of measurement of liquid level drop.

EFFECT: improvement of accuracy, simplification and automation of a process for determination of volumes of drilling and grouting liquids pumped to a well.
