Submersible Electric Centrifugal Pump System

Submersible Electric Centrifugal Pump System (SECPS) in a complete set:

The submersible electric motor serves as the drive for the pump.

The new generation control station provides the functions of power supply, control and protection of the SECPS.

A submersible centrifugal pump (SСP) provides lifting to the surface of the reservoir fluid.

The gas separator separates the gas from the reservoir fluid.

The hydraulic protection protects the cavity of the electric motor from the ingress of reservoir fluid.

The submersible electric centrifugal pump system (SECPS) for oil production, in general, consists of:

  • submersible centrifugal pump (including check and drain valves, pump sections, inlet module or lower section, depending on the order);
  • sludge trap (to be negotiated separately when ordering);
  • gas separator (it is discussed separately when ordering, when completing the installation with a gas separator, the input module is not supplied);
  • slot filter-input module (when ordering, it is negotiated separately, when completing the installation of the reaper, the input module is not supplied);
  • Hydro protection;
  • submersible electric motor;
  • cable line;
  • ground-based electrical equipment (control station, transformer, etc.);
  • telemetry systems;
  • tools, accessories, mounting kits;
  • spare parts (to be specified separately when ordering).

The pump systems have been developed at the most modern level by leading institutes in Russia and the CIS countries. The design of the pump systems is based on world-class technology and its manufacture uses materials developed specifically for submersible equipment and used in defense and space technology.

The system allows pumping out reservoir fluid with a capacity from 12 to 2500 m3/day from a depth of up to 3600 m. The units are supplied in any configuration, which allows the Consumer to have equipment suitable for any well.

Reservoir fluid — a mixture of oil, associated water and associated gas — has the following characteristics:

  • maximum content of associated water, % — 99;
  • hydrogen index of associated water, pH — 6.0-8.5;
  • maximum liquid density, kg/m3 — 1400;
  • maximum kinematic viscosity of a single-phase liquid at which:
    • pump is operated without changing the pressure and efficiency, mm2/s — 1;
    • maximum mass concentration of solid particles for pumps, g/l (%):
      • conventional design — 0.1 (0.01);
      • corrosion—resistant design - 0.2 (0.02);
      • wear-resistant, corrosion-resistant design — 0.5 (0.05);
      • increased corrosion and wear resistance — 1.0 (0.10);
      • when pumps are equipped with a fine filter — 3.0 (0.30);
    • microhardness of particles according to Mohs for pumps, points:
      • conventional, corrosion-resistant, corrosion-wear-resistant design — 5;
      • increased corrosion and wear resistance, wear—resistant design - 7;
      • maximum free gas content at the pump intake is -25% by volume, with the use of a gas separator as part of the installation -55%, with the use of a gas separator-dispersant -65%, with the use of an input dispersing module as part of the installation -30%;
    • maximum concentration of hydrogen sulfide for pumps, g/l (%):
      • conventional, wear—resistant design - 0.01 (0.001);
      • corrosion-resistant, corrosion-resistant design, increased corrosion and wear resistance — 1.25 (0.125);
    • maximum temperature of the pumped liquid, oS — 150 (to be specified separately when ordering)
    • maximum hydrostatic pressure in the suspension area of the installation, MPa – 40.
