Slotted Screen Intake
Application
The slotted screen is used as an intake of ESP system. It protects ESP impellers and diffusers from propping agent after reservoir hydraulic fracturing and from mechanical impurities with cross section size of a particle not less than 100 micrometers*.
How does It work?
The slotted screen intake is installed between seal and lower pump. When formation fluid is coming through the intake mechanical impurities are stopped by the screen on the surface and deposite into the dia hole. Filtration rate depends on a slot size. The length of the intake is sized according to the pump flow rate. Slotted screen intake of any length can be sized to any existing type of pump.
* Upon customer's request it is possible to manufacture slotted
screen intake with lowered filtration rate.
** e.g. of code: N92FS3:
N-Novomet;
92- O.D. (mm);
FS- filter slotted;
3-section length (m).
Main benefits
- The slotted screen filter can be used as an intake of ESP system of any manufacturer due to its universal design;
- Special wire shape and polished surface allow the intake to be self-cleaned;
- Unique design of the intake and high-strength steel material increases filtration rate up to 100 and 200 micrometers;
Wear-resistance of the intake can be considerably increased by silicon carbide intermediate bearings;
- The intake provides reliable operation of equipment in the wells with high content of mechanical impurities;
- ESP run life is increased due to the design of the slotted screen which does not allow hard particles to stop on the surface of the intake;
- It increases overhaul period;
It guarantees low drawdown at high flow rate; It is of multiply use.
Increase ESP run life and oil production.
