Purpose

The jet pump is designed for well development, exploration of wells and intensification of oil inflow from wells.

Design possibilities

Jet Pro 2 allows you to carry out the following technological operations:

 

  • Geophysical research in the mode of set values of depressions by geophysical instruments on a logging cable not exceeding 43 mm in diameter;
  • Reduction of bottomhole pressure and induction of inflow from the formation;
  • Impact on the formation by alternating (cyclic) differential pressures;
  • Multi-cycle hydrodynamic studies from lower to higher depressions with registration of bottomhole pressure with autonomous gauges;
  • Chemical treatment of formations with subsequent extraction of reaction products.
The listed operations can be performed in any combination and sequence.

Principle of operation

  • The device is driven by the injection of the working fluid by pump units located on the surface.
  • The device allows you to create depressions on formations without the use of compressor units.
  • The principle of operation of the device eliminates the possibility of explosive gas-air mixtures and uncontrolled oil and gas manifestations in the well.
  • The device reduces the bottomhole pressure only in the sub-packer interval. The rest of the wellbore maintains normal hydrostatic pressure.
  • As a working fluid for Jet Pro 2, a fluid used for well killing (water, saline solution, surfactant solution) is used.
