摘要： An inflatable packer with a packer body, an inflatable bladder mounted around the packer body, a bladder support mounted around the inflatable bladder, the packer body, the inflatable bladder and the bladder support made of drillable material. A method for reclaiming a borehole extending from an earth surface into the earth, part of which is in a lost circulation zone, the method including closing off the borehole to fluid flow above the lost circulation zone by installing a packer system with an inflatable packer element and a valve apparatus in the borehole above the lost circulation zone, inflating the inflatable packer element with cement, and allowing the cement to set so that the inflatable packer and the valve apparatus effectively seal off the borehole to fluid flow.
