摘要： A technique enables construction of a simplified inflatable packer. An inflatable packer is constructed with a packer reinforcement layer having at least one fiber layer. The fiber layers provide both mechanical and anti-extrusion qualities in a relatively simple and small package. Depending on the desired application, the inflatable packer also comprises an inner bladder layer and other potential layers, such as an outer seal layer. Mechanical extremities are used to secure longitudinal ends of the various packer layers, including the packer reinforcement layer.

摘要： A technique involves a packer formed as an expandable packer with an internal expandable bladder. The expandable bladder is formed with a section that is radially enlarged relative to an axial end of the expandable bladder when the bladder is in a relaxed state. The bladder configuration enables use of a reduced expansion ratio while still allowing expansion of the packer to a desired large diameter.

摘要： A technique involves collecting formation fluids through a single packer. The single packer comprises an outer bladder with drains positioned in the outer bladder to obtain formation fluid samples. Features also may be incorporated into the single packer to limit sealing in the circumferential spaces between the drains and to provide a larger sampling surface than provided simply via the drain surface area.

摘要： An apparatus, system and method of sampling a reservoir fluid is disclosed. An inflatable packer is deployed into a wellbore having one or more fluid ports for receiving the reservoir fluid. The fluid ports are positionable at different longitudinal and/or radial positions. One or more pumps are connected to the fluid ports and are within the packer. A fluid exit may optionally be provided in the packer to expel the reservoir fluid received from one of the fluid ports back into the wellbore.

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.
