METHOD OF PARAFFIN DEPOSIT PREVENTION IN OIL WELL

摘要

FIELD: oil producing industry, particularly, methods of paraffin formation control in production of paraffin-base crude oil. SUBSTANCE: method includes treatment of well fluid flow in tubing pipes with constant magnetic field; simultaneous building-up of negative pressure pulses in well by increase of well production rate for time required for carrying of well fluid to space of fixing pipes to place higher than place of treatment with constant magnetic filed. Then well is changed over to initial operating conditions. EFFECT: higher efficiency of paraffin formation control at various stages of crystallization, increased time between overhauls. 1 tbl
