    摘要: An apparatus that is usable with a well includes a tubular member, an annular body and plugs. The tubular member includes a wall that defines a passageway to communicate a fluid, and an opening extends through the well. The annular body circumscribes the wall, and the annular body includes orifices that are adapted to communicate the fluid with the opening. The plugs are adapted to be moved to controlled positions relative to the orifices to regulate at least one of a flow rate of the fluid through the opening and a pressure differential across the opening.

    摘要: A technique is provided in which a soft landing system is used for connecting upper and lower assemblies in a wellbore. The soft landing system cushions the engagement of an upper well assembly with a lower well assembly and facilitates the controlled engagement of control line connectors. The controlled engagement limits or avoids damage to the control line connectors in well completion operations performed in two or more stages.

    摘要: A hydraulic wiper plug launcher (8) includes a coupler (22) releasably mounted on the upper end of a well casing (9). The outer coupler body (10) has an inner shoulder (49) and an open ended plug container (12) has a stack of wiper plugs (16) compressed therein. The upper end portion of container (12) forms a fluid chamber (S2) above the uppermost wiper plug (16). A precise predetermined volume of fluid is supplied to fluid chamber (S2) for expelling the plugs (16) in a controlled sequence. The length of the fluid chamber (S2) in container (12) increases an amount equal to the length of the wiper plug (16) pushed or expelled from the open lower end of the container (12).

    摘要: Zonal isolation tools and methods of using same are described. The zonal isolation tools include a wellbore sealing member expandable by fluid pressure to contact a wellbore over an initial contact area, an inflation valve open during expansion of the sealing member to the initial contact area and closed upon the fluid pressure reaching a predetermined setting, a vent between the sealing member and a wellbore annulus adapted to open after the inflation valve is closed, and a compressive load imparted to the sealing member via a linear piston to achieve a sealing point at the leading edge of the sealing member. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims.

    摘要: A technique is provided to facilitate connection of multiple stage completions. A first completion stage is deployed at a wellbore location. Subsequently, the next completion stage is moved downhole into engagement with the first completion stage. The completion stages each have communication lines that are coupled together downhole via movement of the completion stages into engagement.

    摘要: A technique is provided in which a contraction joint is used to facilitate connection of well equipment assemblies at a downhole location. The contraction joint accommodates changes in system length during engagement and use or the well equipment assemblies in a wellbore. Additionally, the contraction joint provides a positive indication of joint position and enables resetting of the joint following initial contraction.

    摘要: A wiper plug launching tool includes a body arranged to be lowered into a liner on a running string, the body having a tubular upper portion and a cylindrical lower portion, upper and lower wiper plugs loaded into the lower portion, each of the plugs having upwardly facing elastomer cups that are reduced in diameter during loading, a drive rod movably mounted in the upper portion of the body, a first piston or dart that is pumped down the running string and into engagement with the drive rod so that pressure applied to the first dart forces the rod downward to cause ejection of the lower wiper plug into the liner where cups of the plug expand to provide a moving seal at the lower end of a column of cement, and a second piston or dart that is pumped down into engagement with the first dart to force the rod further downward and cause ejection of the upper wiper plug into the liner where the cups of this plug expand to provide a moving seal at the upper end of the column of cement. A slidable valve is provided adjacent the upper end of the drive rod and is effective to close lateral flow ports upon downward movement of a dart and initial engagement with the drive rod. The drive rod has a piston mounted within a cylinder for cushioned movement upon metering of hydraulic fluid between the piston and cylinder during downward movement of the drive rod. A modification of the invention shown in FIGS. 9-11 utilizes three wiper plugs for sealing the liner.
