Abstract:

The article is devoted to the application of wave action on the bottomhole formation zone (BFZ) in order to increase its permeability and increase the turnaround time, on oil storage tanks and pipelines in order to clean their inner surface from asphalt, resin and paraffin deposits (ARPD). The paper considers in detail the methods of acoustic, ultrasonic, repressive-depressive, vibration impact and their effectiveness in combating ARPD. The use of these methods is due to a drop in the flow rate and injectivity of wells when the bottomhole zone is contaminated, an increase in hydraulic resistance during the accumulation of paraffin deposits in the flow parts and tanks. Hydropulse treatment can achieve 60-80% recovery of bottomhole zone permeability, ultrasonic treatment can achieve a 6-times reduction in oil viscosity.

Keywords: oil, wave action, bottomhole formation zone, asphaltene sediments, ultrasonic impact.
