PROCEDURE FOR TREATMENT OF BOTTOMHOLE ZONE OF PRODUCER Russian patent published in 2014 - IPC E21B43/25 E21B43/27 E21B43/16

Abstract RU 2527085 C1

FIELD: oil and gas industry.

SUBSTANCE: procedure for treatment of bottomhole zone of a producer includes filling in of the productive stratum interval with a solution for asphalt, resin and paraffin depositions with partial flushing to the well bottomhole. Vacuum and pulse simulation is carried out with simultaneous extraction of the reaction products. The interval of the productive stratum is filled in with hydrochloric acid solution, which is flushed partially to the well bottomhole. The process is withheld and vacuum and pulse simulation is carried out with simultaneous extraction of the reaction products. At that in one cycle of vacuum and pulse simulation about 0.01 m³ of liquid is pumped out. During vacuum and pulse simulation upon flushing of the solution for asphalt, resin and paraffin depositions quantity of pulses is increased 3-6 times more than upon flushing with hydrochloric acid solution, moreover volume of the reacted solution to be extracted is equal to the volume of the injected solution for asphalt, resin and paraffin depositions.

EFFECT: improving treatment efficiency of a bore-hole zone.
