Abstract
FIELD: well drilling; applicable in lining of oil and gas wells in course of their completion. SUBSTANCE: method for completion of well construction includes casing of wellbore down to roof of producing horizon. Then, wellbore is expanded against producing horizon. Wellbore is expanded in producing horizon zone up to 1.2-2 outer diameter of flow string. After expansion producing horizon is shut off with impermeable shell in form of shaped pipes. Impermeable shell is lowered simultaneously with flow string. Then, impermeable shell is expanded and flow string is cemented above zone of expansion. After injection of calculated volume of cement mortar and its setting, the formation is subject to secondary opening by perforation of impermeable shell, and work is performed to stimulate inflow of fluid. EFFECT: higher stability of formation filtering zone. 2 cl, 4 dwg
