Apparatus for cementing from a floating vessel |
摘要 |
An apparatus is provided for cementing an oil well borehole from a floating vessel. A sliding sleeve cementing valve is adapted to be interconnected with a casing string. A drill string to be lowered into the casing string includes a drill pipe, an opening positioner connected to the drill pipe for opening the cementing valve, an anchor connected to the opening positioner to provide sufficient resistance between the drill string and casing string to operate a motion compensator on the floating vessel, and an isolation packer connected to the anchor.
