FIELD: mining.
SUBSTANCE: the invention relates to method of well bore maintenance in an underground formation, and to cement composite used for well bore maintenance in an underground formation. The method of well bore maintenance in an underground formation includes preparation of cement composite containing water, cementing material and gas hydrates inhibitor, and placement of the said cement composite into the well bore. The cement composite used for well bore maintenance in an underground formation contains water, cementing material and gas hydrates inhibitor.
EFFECT: production of cements with new composition.
