    摘要: A packer assembly with an enhanced sealing layer is provided. The packer assembly may have an outer bladder with drains. The packer assembly may further have an inflatable inner packer disposed inside the outer bladder such that inflation of the inner packer causes the outer bladder to expand. End pieces may be coupled to the inner bladder and the outer bladder, and flowlines may be in fluid communication with the drains and the end pieces. A piston ring may reinforce the packer assembly. The piston ring may have three or more passive pistons which expand with the packer assembly during testing.
