    摘要: A system and method for attaching and removing equipment from a subsea wellhead in which equipment is lowered and raised on a flexible riser pipe, cables extend from the equipment to the wellhead and are winched in and out to control movement of the equipment adjacent the wellhead. While the cables are being winched in or out, the cables are maintained in tension by the cable reel or a motion compensator, between the equipment and riser pipe, permits the riser pipe to reciprocate vertically with the vessel in response to wave action, while the equipment is insulated from this action during engagement and disengagement with the wellhead. The equipment may include a guide frame, which may be made in two pieces, so that the upper section of the guide frame together with a riser pipe connector, may be released from the remainder of the frame and connector and lifted off by the riser pipe or by buoyancy means. The cable winch system may thereafter be used to reconnect the riser pipe lower connector to the remainder of the equipment. Whether a one or two piece frame is used, after the frame is landed on the wellhead with the equipment spaced from the wellhead, the equipment is preferably lowered into engagement with the wellhead. The motion compensator between the frame and riser pipe may provide this function.

    摘要: A valve employing a coupling disk to rotate the valve member so that rotative force is applied to the valve member in a direction away from the seat during opening of the valve and/or in a direction toward the seat during closing of the valve. Closing force is provided by a spring in a dome chamber and a gas charge in the dome chamber. A float valve controls fluid entry into the dome chamber to trap the gas charge therein while permitting the introduction of liquid from a balance-closure assist line to increase the pressure of the gas charge and assist in closing the valve member.

    摘要: An offshore universal riser system may include a valve module which selectively permits and prevents fluid flow through a flow passage extending longitudinally through a riser string. An anchoring device may releasably secure the valve module in the passage. A method of constructing a riser system may include the steps of installing the valve module in the passage, and installing at least one annular seal module in the passage. The annular seal module may prevent fluid flow through an annular space between the riser string and a tubular string positioned in the passage. Drilling methods may include injecting relatively low density fluid compositions into the annular space, and selectively varying a restriction to flow through a subsea choke in a drilling fluid return line. The riser string, including housings for the various modules and external control systems, may be dimensioned for installation through a rotary table.

    摘要: A wet connector for latchingly connecting an electric cable between surface equipment and a previously installed electrically powered well tool at a remote, downhole location in a well for transmitting electrical energy or signals thereto or therefrom. One form of the wet connector is released electricaly (reverse polarity being used), and another form of the connector is released by tensioning and slackening the electric cable a predetermined plurality of times. Systems using such wet connectors are disclosed, as are methods for their use. The wet connector can be used in conjunction with an electric cable for installing certain tools in a well, especially where it is desirable to deposit such tools gently with no jarring.
