    摘要： Methods and systems for conducting liner drilling and subsequent completion of the drilled section by cementing and anchoring the liner into place. The methods and systems prevent the liner from being cemented in in a bent or corkscrewed configuration. Additionally, there are no exterior components associated with the liner during drilling so as to allow relatively unrestricted return of drilling mud and cuttings.

    摘要： A liner hanger assembly structurally interconnects a casing within a bore hole and a tubular liner suspended from the casing. The hanger body includes a plurality of circumferentially spaced piston bores. A plurality of slips are provided circumferentially about, the hanger body for gripping engagement with an internal surface of the casing. A plurality of pistons are each housed within a respective piston bore and are movably responsive to internal pressure within the hanger body. A sleeve is axially movable with respect to the hanger body in response to axial movement of the plurality of pistons. The sleeve is interconnected with each of the plurality of slips to cause radially outward movement of the slips in response to movement of the pistons. The liner hanger assembly has a high fluid pressure rating for ensuring reliable gripping engagement with the casing, yet creates a comparatively low fluid restriction in the annulus between the casing and the liner.

    摘要翻译： 衬管悬挂组件结构地将钻孔内的壳体和从壳体悬挂的管状衬套相互连接。 衣架主体包括多个周向间隔开的活塞孔。 多个滑动件周向设置，衣架主体用于与壳体的内表面夹紧接合。 多个活塞各自容纳在相应的活塞孔内，并且可移动地响应于衣架主体内的内部压力。 响应于多个活塞的轴向运动，套筒可相对于衣架主体轴向移动。 套筒与多个滑动件中的每一个相互连接，以响应于活塞的移动而引起滑动件的径向向外运动。 衬管悬挂器组件具有高的流体压力等级，用于确保与壳体的可靠的夹紧接合，但是在壳体和衬套之间的环空中产生相对较低的流体限制。

    摘要： The present invention generally relates to an anchoring and sealing tool. In one aspect, downhole tool for use in a wellbore is provided. The tool includes a tubular having a tapered outer surface. The tool further includes an expandable annular member disposed on the tubular. The expandable member has an anchor portion. The tool further includes a seal member disposed in a groove of the expandable annular member. The seal member has one or more anti-extrusion bands, wherein the seal member and the anchor portion are configured to be expandable radially outward into contact with the wellbore as the expandable annular member moves along the tapered outer surface of the tubular.

    摘要： A removable ball seat assembly is disclosed. It features a solid ball seat backed up by segmented dogs pinned to each other and mounted under the ball seat. Upon actuating a downhole tool with fluid pressure applied to a ball on the seat, the pressure is increased and the ball and seat move at a regulated rate. The dogs reach a recess and the ball moves through the seat. Subsequent, larger balls can pass through the seat, with the dogs in the recess, at much smaller pressure drops than the original ball.
