Increasing the efficiency of operating time and reducing maintenance time of transport systems

highly corrosive. All this results in the formation of asphaltene-resinparaffin deposits (ARPD) and stable oil-water emulsions, which in
turn leads to premature failure of downhole pumping equipment. In
this work, the scope of measures to prevent malfunctions of pumping
units is considered. The use of the SONKOR-9701 inhibitor through
a special design of the ESP power cable with a capillary conveying
line for supplying the chemical reagent to the reception delivers the
chemical reagent directly to the required entry point with the most
effective dosage and ensures a prompt change of the dosage and type
of the reagent. With this technology, the reagent is not consumed for
the repletion of the oil column in the annular space; its adsorption is
on the surface of the casing and tubing. Thus, the reagent targeted
with just specific technological causes and the greatest effect is
ensured. Due to the introduction of a special cable with a capillary
conveying line, it is planned to increase the average operating time
for failure and, consequently, reduce the maintenance job at the
Gremikhinsky oil field. It is also predicted the additional volume of
extraction because of a special submersible cable device (SSCD), as
well as by increasing the delivery (capacity) rate of the pump.
