Block-Type Submersible Pump Stations (BKNS) for Oil Field Pressure Maintenance

BKNS is designed:

• - to maintain reservoir pressure in productive formations of oil fields by injection of fresh, formation and waste water (polymers) into the formation;

for pumping oil products (after gas separation);

• * for pumping liquids (contaminated water, oil emulsions, etc.).

Block cluster pumping station BKNS is designed for operation in moderate cold climate (UHL). Storage conditions - U 1 according to GOST 15150-69.

The pumped liquid has the following characteristics: -maximum density, kg/m31400; -hydrogen index of associated pH5,0 - 8,5; -microhardness of particles not more than 5 Mohs points; -total mineralisation, g/l15,9 - 20,3
