摘要： A protective member that is disposed within the longitudinal bore of a well tool, the well tool including an actuating mechanism adapted to be mechanically activated from the longitudinal bore. The actuating mechanism includes an engagement section, preferably a profile. The protective member, preferably a sleeve, substantially covers the actuating mechanism while leaving the engagement section exposed to the longitudinal bore. In a preferred embodiment, the sleeve is slidably disposed within the longitudinal bore between a first position and a second position. A biasing mechanism biases the sleeve into the first position, in which a sleeve first end is proximate the profile. Operation of the apparatus enables a method for preventing the inadvertent mechanical activation of the actuating mechanism of a well tool as peripheral equipment is passed through the longitudinal bore of the well tool.

摘要： A system for pressure testing the seals and fittings associated with at least one communication line passing through a well tool mandrel, each communication line housed within a communication line conduit defined through the well tool and sealingly engaged to each end of its corresponding communication line conduit by way of a fitting and the fittings also sealingly engaged to the communication line conduit. The system generally comprises a testing conduit, a testing passageway system, and a testing plug. The testing conduit is defined in the well tool mandrel. The testing passageway system is defined in the well tool mandrel and provides fluid communication between the testing conduit and the fittings and seals associated with each of the communication line conduits. The testing plug provides fluid communication between a pressure testing source and the testing passageway system. A pressure source is operatively connected to the testing plug, and pressurized fluid is guided from the testing plug, through the testing passageway system, into the communication line conduits, and into contact with the with the fittings and seals associated with each of the communication line conduits. Any leaks discovered as a result of this pressurization indicate the presence of a faulty engagement of the fittings or seals associated with the communication line conduits. This operation is performed prior to inserting the well tool in the well bore and without the pressurization of the well tool internal bore.

摘要： The present invention generally relates to a wellbore tool for selectively isolating a portion of a wellbore from another portion of the wellbore. In one aspect, a method of selectively isolating a zone in a wellbore is provided. The method includes the step of positioning a downhole tool in the wellbore. The downhole tool includes a bore with a first flapper member and a second flapper member disposed therein, whereby each flapper member is initially in an open position. The method also includes the step of moving the first flapper member to a closed position by rotating the first flapper member in one direction. Further, the method includes the step of moving the second flapper member to a closed position by rotating the second flapper member in an opposite direction, whereby each flapper member is movable between the open position and the closed position multiple times. In another aspect, an apparatus for isolating a zone in a wellbore is provided.

摘要： A choke valve assembly is disclosed for controlling the flow of fluid through a production tubing. The valve assembly includes a housing having a plurality of axially aligned apertures and a ported sleeve disposed in the housing. The ported sleeve has a plurality of rows of fluid ports. Each row of ports has at least one port in selective fluid communication with a respective aperture. In the full open position, each aperture is in fluid communication with a port from each row. To choke the flow, the ported sleeve is rotated relative to the housing to reduce the number of ports in fluid communication with the housing. To close the valve, axial force is applied to move the ported sleeve axially relative to the housing.

摘要： A completion string for use in a wellbore includes a main conduit, such as a production tubing, and one or more alternate path conduits, such as shunt tubes, that extend generally in parallel with the main conduit. A flow control device is positioned in each alternate path conduit to control flow through the alternate path conduit. The one or more alternate path conduits may be adapted to carry gravel slurry to perform gravel packing operations. The one or more flow control devices in the one or more alternate path conduits may be actuated to the open position to allow communication of the gravel slurry to multiple zones in the wellbore. Once the gravel packing operation is completed, the one or more flow control devices may be actuated to the closed position to block fluid flow communication between multiple zones through the alternate path conduits during operation of the well. Other types of fluids may be communicated through the one or more alternate path conduits, such as fracturing fluids.
