- Аннотация: The Gremikhinsky oil field contains heavy-grade, high-sulfur, highresinous,paraffin-base crude oil, and the produced reservoir fluid is 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.
