Schematic diagram of an individual installation for the recycling of produced water (scheme No. 1). The installation is placed above the packer, which isolates the perforation zone. The pump is turned upside down with the fishing head down and is located under the electric motor. Water from the above-ground pipeline enters the annulus and then into the pump, where the pump develops the required pressure. Then the liquid is pumped through the tubing pipes through the packer into the absorption formation.

Schematic diagram of an individual installation for downhole fluid pumping (scheme No. 2), where the layers are separated by a packer. The unit is also placed above the packer, isolating the perforation zone. The pump is turned upside down with the fishing head down and is located under the electric motor. Water from the aquifer is supplied to the pump intake through the annular space between the tubing and the production casing. Then the liquid is pumped through the tubing pipes through the packer into the absorption formation.

The pumping installation for Cenomanian water is designed for the extraction and subsequent injection of deep, highly mineralized aggressive Cenomanian waters into the oil reservoir. The working bodies are made of corrosion-resistant high-alloy cast iron; a corrosion-resistant coating is applied to the body and end units.

Schematic diagram of a pit installation using tubing pipes or flexible high-pressure pipes (scheme No. 3). The electric motor has a surface design and is placed on the surface of the well, and the pump is immersed in a dry open pit. The installation, in addition to the pump and electric motor, includes an installation frame, a coupling connecting the pump and the drive. The liquid is supplied through a pipeline directly into the pump at a pressure of up to 4 MPa, and the liquid exits through a pressure pipeline/high-pressure flexible hose.
