摘要： This invention relates to apparatus for scraping the inner surface of a wellbore. A scraper assembly (2) is provided comprising a scraper element (6) incorporating: a generally cylindrical member defined by a wall having a slot extending through the wall thickness; and at least one tooth member provided on the outer surface of the wall for scraping engagement with a wellbore. The present invention thereby provides a scraper assembly which is relatively convenient and inexpensive to manufacture and which may be considered as a disposable item of downhole equipment.

摘要： The present invention relates to a downhole tool (102) for selectively opening and closing a lateral borehole extending from a primary borehole. The tool (102) comprises a body (104) incorporating a wall provided with an opening (116) extending therethrough; a deflector member (106) slidably mounted in the body (104) and having a deflecting surface (126) for deflecting, in use, downhole equipment laterally within the body (104). The deflector member (106) is slidable between an open position, in which the deflecting surface is located adjacent and facing towards said opening so that, in use, downhole equipment laterally deflected by the deflecting surface is directed through said opening, and a closed position, in which the deflecting surface is oriented relative to said opening so as to prevent downhole equipment from being laterally deflected through said opening during use. In either position, equipment may pass into the primary borehole downhole of the primary/lateral junction. The tool (102) also comprises constraining means (138, 140) for restricting movement of the whipstock relative to the body.

摘要： A used radial tyre tread, folded into a minimum of three loops and held in compression, in a lateral external circlip, to form a flexible, resilient, abrasion resistant bollard with anisotropic properties. By extending the lateral external circlip, longitudinally, more tyre treads can be added to form a baffle or a barrier. The removal of the tread section significantly reduces the bulk of the waste tyre.

摘要： A well bore deflector tool which is used primarily for deflecting tools, lining and the like through a window which has been milled in the side of a well bore casing includes a deflector face (3) at an upper end thereof and slips (9, 10) for selectively gripping and releasing a tie back receptacle (8) and/or a well bore casing (6) at a location below the deflector face (3). The slips are operable for gripping in response to engagement of the deflector tool (1) with a tie back receptacle (8). Accordingly, the invention provides a simple and automatic device for locking the deflector tool in a required angular position.

摘要： The present invention relates to downhole apparatus and particularly, but not exclusively, to multi-cycle circulating subs used during downhole drilling operations. Apparatus is provided comprising a piston (242) slidably mounted in a body between positions in which at least one aperture in the body is opened and closed. Movement of the piston (242) is controlled by a pin (86), secured to one of the body and a control member, and a control groove (52) formed in the other of the body and control member for receiving a portion of the pin. An arrangement of elements (232, 276) respectively connected to the control member and body is such as to normally resist axial movement of the control member from a first axial position to a second axial position. A spring (44) is located in a chamber for biasing the piston (242). The chamber is vented by an opening in the body.

摘要： The present invention relates to bypass valves for use in wellbores, particularly but not exclusively to bypass valves used during the setting of hydraulic anchor packers. A bypass valve (2) is provided with a piston (30) slidably mounted adjacent a body member (4) having at least one opening (20) extending therethrough. The piston (30) is moveable between a first position establishing a passage from the interior of the body (4) to the exterior thereof via the at least one opening (20) and a second position isolating the interior of the body (4) from the exterior thereof. A second piston may be provided for increasing, in response to a predetermined fluid pressure differential across the length of the piston (30), the force exerted on the piston (30) by a given flow of fluid through the bypass valve (2) such that the resultant force on the piston (30) is insufficient to move the piston (30) to the second position. Thus, the bypass valve (2) is adapted to provide an indication at the surface of an imminent closure. Once the indication is received, the bypass valve (2) may be closed, without the need for remedial action, by simply increasing the rate of fluid flow.
摘要翻译：本发明涉及在井筒中使用的旁通阀，特别但非排他地在液压锚式包装机设置期间使用的旁通阀。旁通阀（2）设置有可滑动地安装在主体构件（4）周围的活塞（30），该主体构件具有延伸穿过其中的至少一个开口（20）。活塞（30）可以在建立从主体（4）的内部到其外部的经由至少一个开口（20）的通道的第一位置和从主体（4）的内部隔离的第二位置之间移动其外观。可以提供第二活塞，用于响应于活塞（30）的长度上的预定流体压力差，增加通过旁通阀（2）的给定流体流施加在活塞（30）上的力，例如活塞（30）上的合力不足以将活塞（30）移动到第二位置。因此，旁通阀（2）适于在即将闭合的表面提供指示。一旦接收到指示，旁通阀（2）可以通过简单地增加流体流速来关闭，而不需要补救动作。

摘要： This invention relates to hydraulic anchor packers for use in well bores and, more particularly, to inflatable anchor packers. A hydraulic anchor packer (90) is provided having an inflatable packer element (36) incorporating a cylinder (38) and an elastomer sleeve (44) provided on the exterior surface thereof. The elastomer sleeve (44) but free of the cylinder (38) intermediate the end portions. Means are provided for causing fluid from within the cylinder (38) to flow through an aperture (48) and between the elastomer sleeve (44) and the exterior surface of the cylinder so as to radially expand the sleeve (44). Means are also provided for trapping fluid so as to prevent relaxation of the sleeve (44). Pressure relief means (92, 94, 98) permits fluid located exteriorly of the packer (90) to move past the sleeve (44) as the sleeve (44) expands whilst in engagement with a well bore wall during use. Thus, the downhole half of the sleeve (44) may freely expand and displace fluid located below the packer (90).
摘要翻译：本发明涉及用于井眼中的液压锚式封隔器，更具体地说，涉及可充气的锚式包装机。提供一种液压锚定封隔器（90），其具有包括气缸（38）和设置在其外表面上的弹性体套筒（44）的充气封隔器元件（36）。弹性体套筒（44）但没有气缸（38）在端部之间。提供了用于使来自气缸（38）内的流体流过孔（48）和弹性体套筒（44）与气缸的外表面之间的装置，以使套筒（44）径向膨胀。还提供了用于捕获流体以防止套筒（44）松弛的装置。压力释放装置（92,94,98）允许位于封隔器（90）外部的流体在套管（44）膨胀时移动通过套筒（44），同时在使用期间与井眼壁接合。因此，套筒（44）的井下半部可以自由地膨胀并且移动位于封隔器（90）下方的流体。
