摘要： A swellable packer device upon exposure to brine in a well. The device may be swellable to a substantially constant profile in spite of significant fluctuations in brine concentrations. Thus, the likelihood of packer failure due to under-swelling or over-swelling is reduced. Indeed, the packer may be employed for long-term operations or isolations ranging from a couple of weeks to twenty years or more without undue concern over packer failure from under or over swelling.

摘要： A swell packer includes a base tubular; a seal member encircling the base tubular, the seal member swelling radially to a seal equilibrium swell upon contact with a particular fluid; and a disc positioned about the base tubular substantially abutting an end of the seal member but not physically connected to the seal member in a manner that limits the equilibrium swell of the seal member, the disc swelling radially to a first equilibrium swell upon contact with a particular fluid.
