Annotation:

One of the main problems of oil production using the gas-lift method is determining the rational technological regime of gas-lift wells. The use of the gas-lift method requires solving two types of issues: reporting on operation, as well as planning the area of the field operated by the gas-lift method. The solution of the first type questions is the use of physical-mathematical models of processes occurring during the movement of liquid, gas and their mixed movement in a gas-lift well, the second solution is the study of technical-economic indicators of operation, averaged over time and groups of wells. When addressing issues of the technological operating mode of a gas-lift well, it is important to use a systematic approach, which involves consideration of all elements related to the specified complex. It should be noted that the solution to the problems of diagnosing various oil and gas production processes is based on the fact that the time dependence of the flow rate and technological indicators of wells, due to the main amplitude-frequency characteristics, has acyclic or almost cyclic nature, that is, it is presented as wave time series.
