FIELD: oil and gas production.
SUBSTANCE: procedure consists in lifting downhole equipment, in well flushing-out, in borehole gauging, in assembly and lowering underground sand-proof equipment with a valve, in bringing well into service and in assembly and de-colmatage of a filter. According to the invention the filter is made in form of filter elements out of porous silicon carbide. During well operation a bottomhole zone of the well, bottomhole zone of reservoir and withdrawn fluid are effected with heat by transmission of voltage through porous silicon carbide under continuous or periodic mode.
EFFECT: raised efficiency of procedure due to treatment of bottomhole zone of reservoir with its de-colmatage; raised output of well and simultaneously purification of produced fluid from mechanical impurities during operation; increased reliability and duration of well operation due to raised erosion resistance of equipment.
