Mathematical model of the automatic control of temperature modes of gas-field wells

A double circuit multithreads mathematical model of temperature parameters control of a gas-field is developed in the paper. Dynamic certificates of wells and pipe lines are employed to distribute units according to the temperature. They are formed and supported in the actual status by means of the developed information-measuring and control system. An estimation procedure of reliability choice of temperature profile parameters, considering weight coefficients at modes positioning of heaters activity, is developed and applied in the Astrakhan gas-field conditions. The application of the mathematical model enables to eliminate invalid control actions on gas heating systems by using factual technological capabilities of gas heaters on well sites, and it provides high safety operation level of dangerous technological objects.
