    摘要： Sealing elements have lubricating seal profiles for communicating fluid between the sealing elements and the sealed drill string tubular or other oilfield component while the sealed drill string tubular or other oilfield component rotates or moves vertically relative to the seal elements. The same fluid used for drilling may also be used for seal lubrication, such as water, drilling fluid or mud, well bore fluid or other liquid or gas. The sealing elements may be disposed with a seal housing, which may be positioned with a marine riser, or subsea without a marine riser. The seal housing may prevent rotation of the seal elements with the sealed drill string tubular or other oilfield component. Alternatively, the seal housing may be an RCD that allows the sealing elements to rotate. The lubricating seal profiles include a wave pattern, a saw-tooth high film pattern, a downwardly inclined passageway pattern, an upwardly inclined passageway pattern, and a combined upwardly and downwardly inclined passageway pattern. In one embodiment, a stripper rubber seal element may have a lubricating seal profile on the inwardly facing bore surfaces of both its nose and throat sections for sealing with drill string tubulars and other oilfield components having different diameters. Dual seals with two annular spaced apart sealing surfaces, with or without lubricating seal profiles, may seal with a drill string tubular or other oilfield component. In another embodiment, differential pressures across two seal elements may be managed by filling the cavity between the two sealing elements with cuttings-free drilling fluid, mud, water, coolant, lubricant or inert gas at desired amounts of pressure.

    摘要： A system compensates for heave induced pressure fluctuations on a floating rig when a drill string or tubular is lifted off bottom and suspended on the rig, such as when tubular connections are made during MPD, tripping, or when a kick is circulated out during conventional drilling. In one embodiment, a liquid and a gas interface moves along a flow line between a riser and a gas accumulator as the tubular moves up and down. In another embodiment, a pressure relief valve or adjustable choke allows the movement of fluid from the riser when the tubular moves down, and a pump with a pressure regulator moves fluid to the riser when the tubular moves up. In other embodiments, a piston connected with the rig or the riser telescoping joint moves in a fluid container thereby communicating fluid either into or out of the riser annulus.

    摘要： A system and method are provided for a low profile rotating control device (LP-RCD) and its housing mounted on or integral with an annular blowout preventer seal, casing, or other housing. The outer diameter of the lateral outlet flange may be substantially the same as the height of the LP-RCD housing and bearing assembly after the bearing assembly is positioned with the LP-RCD housing. The sealing element may be aligned with the lateral outlet, and may be replaced from above. Different embodiments of attachment members for attaching the LP-RCD housing with a lower housing allow the LP-RCD housing to be rotated to align the lateral outlet with the drilling rig's existing line to mud pits or other locations. In one embodiment, the LP-RCD bearings are positioned radially inside the LP-RCD housing. In another embodiment, the LP-RCD bearings are positioned radially outside the LP-RCD housing. One embodiment allows rotation of the inserted tubular about multiple planes. In still another embodiment, an annular BOP seal is integral with a RCD housing.

In one embodiment, a liquid and a gas interface moves along a flow line between a riser and a gas accumulator as the tubular moves up and down. In another embodiment, a pressure relief valve or adjustable choke allows the movement of fluid from the riser when the tubular moves down, and a pump with a pressure regulator moves fluid to the riser when the tubular moves up. In other embodiments, a piston connected with the rig or the riser telescoping joint moves in a fluid container thereby communicating a required amount of the fluid either into or out of the riser annulus. The system also compensates for heave induced pressure fluctuations on a floating rig when a riser telescoping joint located below a RCD is moving while drilling.
