Task of the dispatcher of the gas producing company as per the volume of production of UGC is sent to the automated control system, which executes the task with the help of a proportional integral differentiating (PID) controller for maintaining the flow rate of UGC in the MCL, which is implemented on the basis of APCS.

Also, at the input of CV of PID-controllers of each LTS TL, a signal of the coefficient of the proportionality factor C p_i , (where i is the LTS TL number), which determines the degree of action of this PID-controller on the control valve (CV) of the gas flow rate through it LTS TL. Value of the coefficient of proportionality C p_i  is determined for each LTS TL by its proportionality coefficient calculation unit depending on the current temperature in the low-temperature separator of said lines by the readings recorded by the ACS with the help of a corresponding temperature sensor.

Abstract: FIELD: oil and gas industry. 
     SUBSTANCE: invention relates to oil and gas industry and can be used for effective pumping of binary mixtures into productive formation. Disclosed is a method of pumping binary mixtures into a formation, comprising determining oil-saturated thickness of formation, formation permeability, initial formation pressure and temperature, construction of at least two wells with parallel boreholes in formation and hydraulically interconnected, pumping separate components of the binary mixture into the respective nearby wells towards each other before mixing with each other to obtain a binary mixture. Prior to pumping, the main direction of crack propagation during hydraulic fracturing of the formation is also determined. Barrels in the formation are horizontal with direction across the main direction of crack propagation in the formation, hydraulic communication between wells is ensured by hydraulic fractures of the formation in horizontal wellbores. After determination of required interval of pumping of binary composition pumping of components of nearby wells is performed successively. First, the first component is pumped through one well, by pushing with the buffer liquid, with the lowering of the liquid level by pumping out in the second below the reservoir pressure. First component is pumped till formation of the required interval of the formation is achieved between well bores, after which pressure is increased in the second well for extrusion of the first component out of cracks into the formation. After the process exposure, the level of the liquid is reduced by pumping in the first well below the formation pressure, and the second component is pumped through the second well until the required interval is reached along the cracks, after which pressure is raised in first well to extrude second component from cracks into formation, and after process exposure, uniform distribution of second component is provided with mixing and interaction with first component in formation interval. 
     EFFECT: disclosed method of injecting binary mixtures into a formation enables more efficient use of components of a binary mixture to reduce unnecessary losses, improve mixing and, consequently, more effective action on the formation with a given binary mixture.
