An ultrasonic technology for productivity restoration in low-flow boreholes
- 45 Downloads
An analysis is presented of the mechanisms for ultrasonic action on processes in oil boreholes. The nature and features of the acoustic flow are examined, together with the scope for controlling the parameters, which is due to the need to devise equipment and technology for low-flow boreholes, with the choice of efficient modes of operation and the provision of conditions under which the restoration of productivity has the maximum possible effect. Scientific principles are formulated that need to be considered in designing the ultrasonic apparatus for processing heavy crude oils. An industrial specimen of such equipment has been built and tested.
