    摘要： Rotating control device related oilfield pressure control is accomplished by upper and lower seal members configured to seal around a tubular, a chamber defined between the upper and lower seal members; and wherein fluid enters and/or exits the chamber via some device or structure. Such a device or structure could be a relief valve, a first accumulator, a pressure control valve, an orifice, and/or a void space in a seal member in a location which contacts the tubular.

    摘要： In one embodiment, a method for drilling a wellbore includes injecting drilling fluid into a top of a tubular string disposed in the wellbore at a first flow rate. The tubular string includes: a drill bit disposed on a bottom thereof, tubular joints connected together, a longitudinal bore therethrough, and a port through a wall thereof. The drilling fluid exits the drill bit and carries cuttings from the drill bit. The cuttings and drilling fluid (returns) flow to the surface via an annulus defined between the tubular string and the wellbore. The method further includes rotating the drill bit while injecting the drilling fluid; remotely removing a plug from the port, thereby opening the port; and injecting drilling fluid into the port at a second flow rate while adding a tubular joint or stand of joints to the tubular string. The injection of drilling fluid into the tubular string is continuously maintained between drilling and adding the joint or stand to the drill string. The method further includes remotely installing a plug into the port, thereby closing the port. The first and second flow rates may be substantially equal or different.

    摘要： An expandable threaded connection between segments of expandable tubulars that provides a high bearing pressure seal at a specific area along the pin and box members is disclosed. The invention utilizes a “groove” in a surface of the box member and a corresponding “rib” on the pin nose. The radial expansion of the tubulars causes the pin to become shorter in length, thereby causing the pin nose to retract from the back of the box member. As the pin nose retracts, the rib on the pin nose moves backward until a portion of the rib contacts a portion of the groove in the box member. The point of contact between the rib and the groove creates a metal-to-metal seal between the pin and box members. Because the point of contact between the rib and the groove is a relatively small area, the force acting on the point of contact generates a high bearing pressure that is equal to or greater than the internal pressure within the expandable tubulars and, thus, generates a high pressure seal.

    摘要翻译： 公开了一种可扩展管状部分之间的可扩展螺纹连接，其在沿着销和箱构件的特定区域处提供高的轴承压力密封。 本发明在箱体的表面中使用了一个“槽”，并在针鼻上使用了相应的“肋”。 管的径向膨胀导致销的长度变短，从而使销头从箱构件的后部缩回。 当销尖缩回时，销尖上的肋向后移动直到肋的一部分接触箱体中凹槽的一部分。 肋和槽之间的接触点在销和箱构件之间产生金属对金属的密封。 因为肋和槽之间的接触点是相对小的面积，所以作用在接触点上的力产生等于或大于可膨胀管内的内部压力的高承载压力，因此产生 高压密封。

    摘要： An expander tool includes segments capable of deflecting inward in response to a restriction encountered while expanding a tubular downhole. The expander tool includes an inner mandrel having a tapered surface about its outside diameter, the segments disposed around the inner mandrel with corresponding tapered surfaces in contact with the tapered surface of the inner mandrel and a compression sleeve disposed around the inner mandrel. A compressive load on the compression sleeve applies a preload force biasing the segments to a raised position on the tapered surface and hence an extended position. This preload enables expansion of the tubular with the segments in the extended position. Upon reaching the restriction, an increased pull force on the expander tool forces the segments down the tapered surface of the inner mandrel against the bias of the preload to a retracted position such that the expander tool assumes a smaller maximum outer diameter.
