Details
Component layout of ESP-SRPU
Purpose
Installation for dual operation of two objects with ECPU offtake from the lower product formation (and SRP from the upper product formation). The units are designed for dual operation of two objects separated by the packer with the possibility, if necessary, of separate lifting, metering, and transportation of products.Application
Oil-producing wells with two formations.Advantages
Complete information about the work of the reservoirsDesign
A packer with an on-off device, a tubing string, a string of standard or hollow rods, a top SRP, a bottom ESP with a cable, a casing and a shank for connection to the lower formation. Surface equipment: SRP motor, ESP control station, two-channel wellhead fittings.Work principle
The products of the lower layer enter through the wall packer into the case with the electric motor and through the entry unit to the ESP intake and are pumped by it through the check valve into the cavity of the tubing and further to the surface. The products of the upper layer enter through the annular space into the channel for the intake of the SRP and are pumped by it into the column of tubing where they are mixed with the products of the lower layer and lifted to the surface. The pump is driven by rods. The operating mode of the installation is determined depending on pumps used and their motors.Operating limitations
• Nominal diameter of the production casing string not less than 5.75 in;• Availability in the well at least two penetrated objects;
• Distance between the objects not less than three meters;
• Leak tightness of the production casing string and absence of the annulus hydrodynamic connection between the objects;
• Drift angle buildup not more than 2° per 32.81 in;
• Absence in the production well string of narrowing along the inside diameter in the form of slurry cake and packers in the interval of the target descent of the installation underground part.
