The main features of the development of gas and gas condensate fields in conditions of active inflow of boundary and bottom waters into productive deposits and production wells are considered. Various ways of optimizing the operating conditions of highly water-cut wells at the final stage of field development are characterized. On the basis of numerous studies, the expediency and geological and technological conditions for the use of mechanized methods of operating water-cut wells have been substantiated. Using the Schlumberger PipeSim software package, a study of the influence of the parameters of electric submersible pumps on the performance characteristics of water-cut wells was carried out. Based on the research results, the value of the water factor was established, above which the flowing operation of the gas well ceases. To restore the productivity of the well, an ECP of the REDA DN3100 type was selected and the effect of its various operating frequencies on the bottomhole pressure, liquid and gas flow rates was investigated. Based on the results of the studies carried out, graphical dependences of the gas, liquid and bottomhole pressure on the operating frequency of the ECP were built. According to the results of the studies performed, it was found that the flow rates of gas and liquid increase with an increase in the operating frequency of the ECP. Based on the results of the calculations carried out, a comparative analysis of the technological parameters of the operation of a water-cut well with the use of ECP of the REDA DN3100 type and without its use was carried out. The research results made it possible to derive dependencies that allow predicting the technological parameters of the operation of water-cut wells. Based on the results of the calculations, the high technological efficiency of the use of ECP for the intensification of the development of oil and gas fields in conditions of intensive watering of productive deposits and production wells has been proved.
