Abstract
An inflatable packer is disclosed and includes an elastomeric tubular body adapted for radial expansion and having a longitudinal axis. The packer includes an elastic outer cover surrounding said tubular body, and coupling members disposed on each end of the tubular body. A plurality of substantially concentric reinforcing layers are stacked atop each other and sandwiched between the body and the cover. Each layer includes spirally wound reinforcing members extending the length of the body between the coupling members. The reinforcing members and each of layers has a uniform lay angle at any circumferential position along the length of the body, with a lay angle of the members in one of the layers differing from the lay angles of the remaining layers at the same circumferential position along the length of the body.
