Abstract
An inflatable well packer includes several annular layers of material, consisting of a series of oriented fibers encapsulated in a resin, the fibers being oriented in directions relative to the direction of the circumference of the annular layers such that pressure from the bore through the annular layers causes changes to the orientations of the fibers, thus causing inflation of the well packer, the fibers within each layer being oriented along the length of the layer, so that a portion of them are oriented at the lock up angle.
