摘要： A packer (100) for sealing an annular region in a wellbore is provided. The packer (100) includes a packing element (150) which is held through bi-directional forces. The packer first comprises an inner mandrel (110). Disposed around the inner mandrel are three tubulars: a top sleeve (120), a bottom sleeve (130), and a booster sleeve (140). A packing element (150) is disposed circumferentially around the outer surface of the booster sleeve (140). The top sleeve (120) and bottom sleeve (130) each include an upper compression member (124,134) which rides across the booster sleeve (140) in order to compress the packing element (150). The packing element is expanded outward from the packer to engage a surrounding string of casing (10) through compressive forces provided by the top and bottom sleeves (120,130). Thereafter, differential pressure applied above or below the packer acting on the packer element (150) and booster sleeve (140) may provide additional compression of the packer element (150).
摘要翻译：提供了用于密封井眼中的环形区域的封隔器（100）。封隔器（100）包括通过双向力保持的包装元件（150）。封隔器首先包括内心轴（110）。围绕内心轴设置有三个管：顶套（120），底套（130）和增压套（140）。填充元件（150）周向地设置在增压套筒（140）的外表面周围。顶套（120）和底套（130）各自包括越过增压套（140）的上压缩构件（124,134），以便压缩填料元件（150）。包装元件从封隔器向外扩展，通过由顶部和底部套筒（120,130）提供的压缩力来接合外壳（10）的周围的串。此后，作用在封隔器元件（150）和增压套筒（140）上的封隔器上方或下方施加的压差可以提供封隔器元件（150）的附加压缩。

摘要： Embodiments of the present invention relates to hydraulically actuated tools, which may be used to actuate a liner hanger assembly. In one embodiment, the present invention provides a hydraulic setting tool (113) for use in wellbore operations. The setting tool includes a first tubular member (130) and a second tubular member (120) disposed around the outer diameter of the first tubular member. A piston (110) is mechanically attached to an upper portion of the second tubular member and adapted to move axially in relation to the first tubular member. The piston acts to transmit a force to the second tubular member. A slip assembly (162) is operatively connected to the second tubular member and the second tubular member transmits the force to the slip assembly thereby actuating the slip assembly.

摘要： The present invention provides a connector arrangement for connecting and locking tubular members. The connector consists of two tubular members (100, 110) and a coupling member. The tubular members are threaded together to create a threaded connection. The locking arrangement is provided by a pathway (120, 130) formed on the tubular member whereby a locking member (500) can be inserted in to the pathway to lock the threaded connection. The locking arrangement may also be provided by a plurality of castellation members (614, 714) disposed on each tubular member. The connector may also have a separate coupling member (620) which has opposite right-hand (622R) and left-hand (622L) threaded ends to threadedly mate with the threads of the two tubular members.
摘要翻译：本发明提供一种用于连接和锁定管状构件的连接器装置。连接器由两个管状构件（100,110）和联接构件组成。管状构件被拧在一起以形成螺纹连接。锁定装置由形成在管状构件上的通道（120,130）提供，由此可以将锁定构件（500）插入通路以锁定螺纹连接。锁定装置也可以由设置在每个管状构件上的多个城堡构件（614,714）提供。连接器还可以具有单独的联接构件（620），其具有相对的右手（622R）和左手（622L）螺纹端，以与两个管状构件的螺纹螺纹配合。

摘要： A ball dropping assembly (350) for dropping one or more objects, such as spherical balls, (5,5',5") into a wellbore (7). The assembly comprises a seat (330) for retaining a ball before it is released. The assembly may also comprise a ball feeding channel (380) for feeding additional balls onto the seat. A ball retaining lever (40) is provided to selectively receive and retain balls onto the seat (330), and then to release the balls individually into the wellbore (6). In one embodiment, the assembly is attached to a side bore (4) in fluid communication with a main bore in a cementing head (105). The ball-retaining lever (40) rotates into the bore (6) when releasing a ball (5'). When a plug (8) is released into the bore from a cementing head (105), the plug (8) will trip the lever (40), causing the ball-retaining lever to rotate back towards the ball-retained position. Thus, the ball dropping assembly also serves as a plug release indicator.
