Cavitating Hydrovibrator
CAVITATING HYDROVIBRATOR
The high-frequency cavitating hydrovibrator is used for the vibratory rotary drilling of firm rocks. The advantage of this method is that it combines the positive characteristics of vibrating and rotary drilling methods. During such combined method of drilling there are not only static forces to the rock from the rock cutting tool, but also dynamic influences of periodic character (high frequency shock impulses). The rock is not only crushed and spalled by rock cutting tool under the influence of these forces in the impact moment, but is cut off or spalled during rotation of drilling tools under the influence of static loads to the breed.
Application and field of application:
The high-frequency cavitating hydrovibrator of oscillations is designed to the intensification of borehole drilling irrespective of depth and hardness of penetrated breeds.

Field of application:

  • Expendable well;
  • Oil and gas drilling;
  • Hard-rock borehole drilling;
  • Technological drilling.
Applicable for the drilling of vertical and horizontal boreholes.
Cavitation hydrovibrator does not require essential expenses for implementation and can be used for any equipment where the washing liquid is used.
The main advantages of the hydrovibrator
  • The supplementary power source is not necessary;
  • Readjustment for deferent drilling depth is not necessary;
  • Expansion of longitudinal vibration upstream to drill string does not exist;
  • Movable and rotation equipment detail/part does not exist;
  • Increase of core recovery for drilling of fractured rock;
  • Limit on drilling depth does not exist;
  • Limit on drilling diameter does not exist practically;
  • In consequence of hydrovibrator transforms the stationary flow of washing fluid in to pulsating stream the lifespan of rock-cutting tools is increased due to following factors:
    • Cleaning power of rock-cutting tools is increased;
    • Cooling of rock-cutting tools is increased;
    • Return of drilled solids is increased;
  • Hydrovibrator creates high-frequency accelerations up to 20000 Hz;
  • Hydrovibrator usage does not effect negatively to drilling equipment;
  • Vibration reducing of drilling equipment and rig was fixed during the testing;
  • Consumed power to drillstring rotation is reduced by 20-25 % due to hydrovibrstor usage. This allows to increase the axial load;
  • Our equipment allows changing drilling manner to the vibration-rotational method of drilling with minimum expenses and does not have weaknesses inherent in existing hammers and vibrators such as readjustment for deferent drilling depth, breakaways, keying on, short life and other.

Hydraulic Impulse Generator
Hydraulic Impulse Generator
Hydraulic Impulse generator is intended for increase of the minerals extraction efficiency by increasing fracturing of rocks by a way of pulsed influence of working liquid under the pressure to the layer .

Field of application:

  • Production stimulation and increasing of wells output for the following extractable resources as oil, gas, shale gas, sulphur, water and other;
  • Coal-bed degassing;
  • For other minerals extraction with caustic wash manner.
Applicable for the vertical and horizontal boreholes.
Hydraulic Impulse generator does not require essential expenses for implementation.

The main advantages of the Generator

  • Simple design;
  • The supplementary power source is not necessary;
  • Readjustmentof generator for the deferent well depth is not necessary;
  • Long life of failure-free working time;
  • Well treatment according this technology allows to increase the output of wells in some times;
  • Well treatment according this technology allows to keep the well operational property during 1 year;
  • Expansion of longitudinal vibration upstream to pipe column does not exist;
  • Movable and rotating details/parts of equipment do not exist;
  • Limitonthe well depthdoes not exist;

Last world tendencies show us the severization of environment protection standards. France, Germany, Bulgaria, Canada has already forbidden to use the hydraulic fracturing and other countries such as Sweden is planning to refuse it.
