摘要： A packer assembly has an inner expandable packer. An outer layer having sealing bodies may be disposed about and/or positioned on the outer surface of the inner expandable packer member. Each of the sealing bodies may have an elastomeric body, and one or more flowlines may be embedded in the elastomeric body of each of the sealing bodies. The sealing bodies may be located in grooves in the inner expendable packer member. The sealing bodies may contact a surrounding casing or a surrounding formation to form an annular seal; in an embodiment, the sealing bodies and the inner expandable packer member may contact a surrounding casing or a surrounding formation to form an annular seal. The sealing bodies may be non-integral with each other and/or separable from each other.

摘要： A technique improves the formation of dependable seals along wellbores. A packer is constructed with a plurality of elastomeric layers and an internal mechanical layer that extend between mechanical extremities. One or more of a variety of features can be added to, or used in conjunction with, the packer to reduce wear and the potential for detrimental damage during use of the packer.

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.

摘要： A system and/or a method collects formation fluids using a single packer with expansion rings and/or an irregular sealing layer. The packer may have an expansion ring extending around an outer circumference. The expansion ring may seal a portion of a wellbore to sample fluid from a formation. An irregular sealing layer may facilitate leaking between drains of the packer. The irregular sealing layer may have grooves through which fluid may flow. The irregular sealing layer may be composed of fibers and/or plastic.
