摘要： For wellbore fluid treatment, sliding sleeves (120,130A-B) deploy on tubing in a wellbore annulus (14). Operators deploy a plug (126) down the tubing to a first sleeve (120). The plug seats in this first sleeve, and pumped fluid pressure opens the first sleeve and communicates from the tubing to the wellbore annulus. In the annulus, the fluid pressure creates a pressure differential between the wellbore annulus pressure and a pressure chamber on second sleeves on the tubing. The resulting pressure differential opens the second sleeves so that fluid pressure from the tubing can communicate through the second open sleeves. Using this arrangement, one sleeve can be opened in a cluster of sleeves without opening all of them at the same time. The deployed plug is only required to open the fluid pressure to the annulus by opening the first sleeve. The pressure chambers actuate the second sleeves to open up the tubing to the annulus.
摘要翻译：对于井筒流体处理，滑套（120,130A-B）部署在井筒环（14）中的管道上。操作者将管道上的插头（126）部署到第一套筒（120）上。该第一套筒中的塞座和泵送的流体压力打开第一套筒并从管道连通到井筒环。在环形空间中，流体压力在井筒环空压力和管道上第二套管上的压力室之间产生压力差。所产生的压力差打开第二套筒，使得来自管道的流体压力可以通过第二开放套管连通。使用这种布置，一个套筒可以在一簇套筒中打开，而不会同时打开它们。部署的插头只需要打开第一个套筒就可以将流体压力打开到环空中。压力室致动第二个套管以将管道打开到环空。

摘要： A swellable packer (200) with an enhanced sealing ability comprises a tubular body (110), a swellable element, and a filler ring (210) disposed about the tubular body between the tubular body and the swellable element. The filler ring is formed of a material harder than the swellable element (120). The filler ring enhances the sealing ability of the swellable packer. Any number of filler rings may be used. The filler ring or rings may be fixed to the tubular body or may be unfixed.
摘要翻译：具有增强的密封能力的可膨胀的封隔器（200）包括管状本体（110），可膨胀元件和填充环（210），其设置在管状本体与可膨胀元件之间的管状本体周围。填料环由比可膨胀元件（120）硬的材料形成。填料环增强了可膨胀封隔器的密封能力。可以使用任何数量的填充环。填料环或环可以固定到管状体上，或者可以不固定。

摘要： A downhole tool, such as a packer or liner hanger, has a mandrel on which slips are disposed for engaging a surrounding tubular downhole. When the tool is being run in or out of the hole, at least one magnetic component magnetically retains the slip adjacent the mandrel so the slip can be held away from the surrounding tubular. When the tool is set downhole, the initial magnetic retention can be broken, and the slips can be moved away from the mandrel to engage the surface of the surrounding tubular.
摘要翻译：诸如封隔器或衬管悬挂器的井下工具具有心轴，在其上设有滑动件用于与周围的管状井下接合。当工具进入或离开孔时，至少一个磁性部件磁性地将滑动件保持在心轴附近，使得滑动件能够远离周围的管状物。当工具设置在井下时，可以破坏初始磁保持，并且滑动件可以从心轴移开以接合周围管状物的表面。

摘要： A device and method that allows a gravel slurry to placed in a wellbore from the toe towards the heel to reduce the pressure acting upon the heel of the wellbore during the gravel placement operation. By reducing the pressure acting upon the heel gravel slurry may be placed in longer sections of the wellbore in a single operation.
摘要翻译：一种装置和方法，其允许砾石浆料从脚趾放置在井眼中，以在砾石放置操作期间降低作用在井筒的跟部上的压力。通过降低作用在脚跟上的压力，砂浆可以在单个操作中放置在井筒的更长的部分中。
