METHOD OF REMOVING PARAFFIN DEPOSITIONS FROM WALLS OF PUMP-COMPRESSOR TUBING

摘要

FIELD: oil and gas production industry. SUBSTANCE: according to method, installed into well is ultrasonic converter, and oscillations are generated. Ultrasonic converter is located in zone of maximal thickness of paraffin deposition. Determined is natural frequency of radial and radial-angular modes of pump-compressor tubing filled with oil having paraffin inclusions. Generated in pump-compressor tubing are resonance oscillations at given frequencies. Intensity of vibration treatment is maintained up to separation of paraffin depositions and solving them in oil. EFFECT: higher efficiency. 2 dwgd
