摘要： Drill pipe protection rings for filling external identification slots in drill pipe tool joints prevent damage to the internal seals of a drilling head. The rings are formed from resilient elastomeric materials. In cross-section, each ring has slightly convex inner and outer surfaces, and a series of circumferentially spaced-apart, hemispherical bumps located along its inner surface. One ring is mounted within each slot on each drill pipe section. The rings stretch slightly while being installed, but form a tight fit once they are properly seated. When installed, the outer surfaces of the rings will protrude slightly outward from or beyond the slots. The hemispherical bumps help align and center the rings within the slots. Without the rings, sharp edges of the slots on the drill pipe tool joints could cause severe damage as they passed through the drill head. However, with the rings, the outer surfaces of the slots are substantially filled to prevent their edges from cutting or gouging the elastomers.
摘要翻译：用于在钻杆工具接头中填充外部识别槽的钻管保护环可防止损坏钻头的内部密封。环由弹性弹性体材料形成。在横截面中，每个环具有略微凸起的内表面和外表面，以及沿其内表面定位的一系列周向间隔开的半球形凸块。一个环安装在每个钻杆部分的每个槽内。戒指在安装时稍微延伸，但一旦安装正确，就会形成紧身型。当安装时，环的外表面将从狭槽向外突出或突出。半球形凸块有助于使槽内的环对准并居中。没有环，钻杆工具接头上的槽的尖锐边缘可能会在穿过钻头时造成严重损坏。然而，通过这些环，槽的外表面基本上被填充以防止其边缘切割或刨削弹性体。

摘要： A splitter assembly 10 is positioned downhole within a conductor 50 for separating two or more tubular strings placed within the conductor. A splitter housing may include a first bore 26 and a second bore 28 for separating a first well from a second well, and a plug 24 positioned in one of the bores including a top face 25 sloping downwardly toward the other bore. One or more guide plates 18 secured to the splitter housing and positioned above the plug guide a bit or other tool toward one of the first bore and the second bore. The splitter housing 10 may be positioned along the conductor 50 after the conductor is jetted in place. According to the method, the plug in one of the bores is retrieved after a casing is run in one well, so that the second bit and the second casing will pass through the bore which previously included the plug.

摘要： A drilling head has a body which lands in an external housing. The body is removably secured to the housing with an annular split ring which is moveable in response to a cam member. The body has an outer body and a rotatable inner body with an axial bore. An annulus extends between the inner and outer bodies. Inlet and outlet ports communicate hydraulic fluid to the annulus which is sealed. The inner body has a gripping member with inner and outer portions. The inner portion has a solid annular elastomer which is free to slide radially relative to the inner body. The outer diameter of the inner portion abuts the outer portion. The outer portion has an energizable elastomer with an annular cavity. The cavity communicates with the annulus through a passage. A primary seal extends from a lower end of the inner body. The seal has a conical elastomer and reinforcement webs to give the elastomer greater rigidity in the upward direction. Drill pipe having a plurality of tool joints is lowered through the bore of the drill head. As tool joints are lowered through the primary seal, the elastomer and ribs flex outward. As the tool joints exit the primary seal, it snaps back and seals around the drill pipe. During drilling, the gripping member is energized to grip and provide a secondary seal around the drill pipe, thereby causing the inner body to rotate with the drill pipe.
摘要翻译：钻头具有一个位于外壳中的主体。主体可拆卸地固定到壳体上，该环形开口环可响应于凸轮构件而移动。主体具有外部主体和具有轴向孔的可旋转内部主体。环形体在内部和外部主体之间延伸。入口和出口将液压油传送到被密封的环形空间。内体具有内部和外部的夹持构件。内部具有固体环形弹性体，其相对于内体自由地径向滑动。内部的外径与外部部分抵接。外部具有带有环形空腔的可激发弹性体。空腔通过通道与环带连通。主密封件从内体的下端延伸。密封件具有锥形弹性体和加强筋，以使弹性体在向上方向上具有更大的刚性。具有多个工具接头的钻管通过钻头的孔下降。当工具接头通过主密封件降低时，弹性体和肋条向外弯曲。当工具接头离开主密封件时，它将卡扣并密封在钻杆周围。在钻孔期间，夹持构件被通电以夹紧并且提供围绕钻杆的次级密封，从而使内部主体与钻杆一起旋转。

摘要： An apparatus for remotely cutting a broken guideline extending from an underwater guide post comprising a frame, a clamping mechanism for clamping the frame to the guide post in a predetermined location, a pair of opposed cutting jaws pivotally coupled to the frame, and a remotely actuated power device for pivoting the jaws across the longitudinal axis of the broken guideline to sever the guideline from the guide post. The cutting jaws are pivoted about the same axis and are actuated by a U-shaped driver slidably movable along the frame. The clamping mechanism comprises a pair of opposed jaws receivable in an annular groove in the guide post. Above the cutting jaws are a pair of pivotal loom jaws which guide the assembly on the post and also deflect any interfering portion of the broken guideline extending along the side of the post.
