INFLATABLE REINFORCED DOWNHOLE PACKER

摘要

An inflatable reinforced downhole packer comprising two end members (14, 15) and an elastomeric tubular element provided with reinforcing members arranged at a slight angle (around 10-15 DEG ) to the longitudinal axis of said element. The reinforcing members are arranged in interlaced or "pressure" webs and the tubular element is combined with a longitudinal cord assembly (32) which, on inflating the element, limits strain around its ends in the regions where said element is joined to the end of the packer.
