摘要: A guide assembly for running a liner through a borehole extending through a subterranean formation, the guide assembly having a central axis, a first end configured to be coupled to the liner, and a second end opposite the first end. The guide assembly includes a guide shoe disposed at the second end, a drive assembly including a radially outer housing, and a rotor concentrically disposed in the housing. The rotor has a first end distal the guide shoe and a second end fixably coupled to the guide shoe, and is configured to rotate about the central axis relative to the housing about the central axis.

摘要: A downhole tool for enlarging a borehole, the tool including a body having a central axis, an uphole end, a downhole end, a bore extending from the uphole end, and an aperture extending radially from the bore to a radially outer surface of the body. Additionally, the tool includes a mandrel disposed in the bore, the mandrel having a first end, a second end, a radially outer surface, and a radially inner surface. The mandrel outer surface includes an inclined surface. Further, the tool includes a first blade disposed in the aperture. The first blade has a radially retracted position and a radially extended position configured to engage with a borehole sidewall to enlarge the borehole. The mandrel is configured to translate axially relative to the body to slide the inclined surface along the first blade to transition the first blade between the radially refracted and extended positions.
摘要翻译: 一种用于扩大钻孔的井下工具,所述工具包括具有中心轴线的主体,井眼端部,井下端部,从所述井上端部延伸的孔以及从所述孔径向延伸到所述主体的径向外表面的孔 。 此外,该工具包括设置在孔中的心轴,心轴具有第一端,第二端,径向外表面和径向内表面。 心轴外表面包括倾斜表面。 此外,该工具包括设置在孔中的第一刀片。 第一刀片具有径向缩回位置和径向延伸位置,该位置被配置为与钻孔侧壁接合以扩大钻孔。 心轴被构造成相对于主体轴向平移以沿着第一刀片滑动倾斜表面,以使第一刀片在径向折射和延伸位置之间转变。
