摘要： A clamp for supporting a subsea wellhead and attached casing string preparatory to installing same in a well, and slip bowl assembly for running a drill pipe cementing string inside the casing string. The clamp comprises two hinged together clamp halves with a connector to permit the clamp to be locked about a subsea wellhead. Half-circle cutouts in each clamp half form a clamp bore when the clamp is closed. The clamp bore has a grooved profile to mate with a grooved profile on the exterior of the subsea wellhead. When the subsea wellhead is clamped in place, with the clamp resting on the rig floor, a slip bowl assembly having a grooved base plate is placed atop the clamp.

摘要： A protector for placement over subsea wellheads. A main body is cylindrical, with an inner diameter of sufficiant size to fit over a subsea wellhead. One end of the main body has a cap across it. A vent and a pump-through port, which permits pumping in of corrosion inhibitors, is in the cap. The open end of the main body has an outwardly flaring skirt to help guide the protector into place over the wellhead. The main body is formed from polyurethane via molding or other suitable methods.

摘要： Apparatus for efficient cleaning of downhole equipment in boreholes, especially oil and gas wells drilled offshore from floating drilling vessels. The apparatus is a wash tool having an elongated central body with a longitudinal bore therethrough. A plurality of integral, outwardly-extending blades radiate outward from the central body. Wash ports extend radially from the longitudinal bore through the body of the blades, to the outermost surface of the blades and exiting at that point. Spiral or straight blades may be employed. A reduced diameter, extended nose portion is attached to the lower end of the tool. Removable jet nozzles may be installed in the wash ports near the outermost blade faces, to create a high velocity wash stream.
