Abstract

The article provides recommendations for the development and study of wells with jet devices, depending on the nature of the inflow after hydraulic fracturing. Existing solutions for well development and exploration do not allow getting rid of complications after hydraulic fracturing, such as active proppant removal from the bottomhole zone with overfilling of bottom holes and a decrease in well flow rates. The use of jet pumps of the design proposed in the work makes it possible to effectively develop wells, reduce the time for putting them into operation, conduct high-quality hydrodynamic studies and obtain filtration parameters of the formation. To develop recommendations for the development and study of wells, depending on the nature of the inflow after hydraulic fracturing, reports on the performance of work on the wells of the Russkaya area, Vostochno-Messoyakhskoye field, and Yamburgskaya area were studied. The pressure build-up curve was processed on each well under study. The data obtained were processed according to D. Horner's method.
