METHOD OF TREATMENT OF BOTTOM-HOLE FORMATION ZONE

摘要

FIELD: oil and gas production. SUBSTANCE: method contains pumping in alcohol solution of surfactant dispersed with gaseous agent into bed, the solution being preliminarily treated with alkali. As a result, permeability of well bottom zone under conditions of watering and deposition of liquid hydrocarbons in the bed and on the bottom is considerably increased; large number of beds and seams is covered by treatment, whose efficiency is thus enhanced. EFFECT: increased productivity of well.
