On approaches to classification of oil-gas industry waste and by-products of oil processing
The paper analyzes the existing methods of shifting the oil well into steady production state. It shows that most control systems that have the bore-hole electric-centrifugal pump use the sensors of dynamic level of liquid. On the basis of the analysis of mathematical model of the oil well the method of its shifting into steady production state without the sensors by means of the open-loop control system is proposed. The analytical expressions are made up, allowing to calculate the parameters of the control input which provides achievement of the required value of dynamic level of liquid in the oil well according to its known parameters.
