METHOD OF WELLBORE TREATMENT

摘要

FIELD: construction of wells of various application, particularly, drilling and completion of oil and gas wells. SUBSTANCE: method includes supply of hydraulic pressure jets of mud onto well walls in course of well drilling. Introduced into mud is portland cement with concentration of 7-50 wt. % for formation of cemented wellbore screen 20-30 mm deep. Said screen provides for wellbore sealing under repression of 15 Mpa and depression of 15 Mpa. EFFECT: increased efficiency of isolation of well permeable walls. 1 ex
