摘要： An apparatus for controlling fluid flow in a wellbore includes a reactive element that reacts when exposed to a fluid and a flow control device configured to control a flow of the fluid. The flow control device may be actuated by a reaction of the reactive element to the fluid. In embodiments, the reactive element reacts by exhibiting a change in a material property. The reaction of the reactive element may be reversible. In embodiments, the reactive element may be a shape memory polymer. The flow control device may include an actuating element operably coupled to the reactive element. The reaction of the reactive element to a given fluid releases the actuating element to actuate the flow control device.

摘要： A cut-and-pull spear is configured to obtain multiple grips in a tubular to be cut in tension. A lock feature holds the set position of the slips and seal. The lock can be defeated with an axial force that retracts a spring-loaded dog, and the lock can be reset to the run-in position, with the slips and seal retracted, so that the assembly can be repositioned in the same trip for another cut. A cam surface prevents setting the slips and seal until the spear is relocated to the next desired cut location or removed from the wellbore. The lock can be defeated with picking up or with a pressuring up on a dropped ball for an emergency release. A surface signal of the release is provided by a stack of disc springs that have to be compressed to release the lock.
摘要翻译：拔拉矛配置成在管状中获得多个夹具以被拉紧。锁定功能保持滑盖和密封件的设定位置。锁定可以通过使弹簧加载的狗缩回的轴向力而被击倒，并且锁可以被复位到导入位置，同时滑移和密封缩回，使得组件可以在同一行程中被重新定位以供另一个切。凸轮表面防止设置滑块并密封，直到矛被重新定位到下一个所需的切割位置或从井筒移除。锁可以通过拾起或者在落下的球上施加压力来进行紧急释放。释放的表面信号由必须被压缩以释放锁的碟形弹簧堆提供。

摘要： A coiled adaptive seat is held to a smaller diameter for delivery with a tool that can feature a locating lug for desired alignment of the seat with an intended groove in the inner wall of a tubular. The release tool retracts a cover from the seat allowing its diameter to increase as it enters a groove. Alternatively the adaptive seat is released near the groove and pushed axially in the string to the groove for fixation. Once in the groove the inside diameter of the string is a support for a blocking object so that sequential treatment of parts of a zone can be accomplished. The blocking object is removed with pressure, dissolving, milling or disintegration leaving a narrow ledge in the tubular bore from the seat that can simply be left in place or milled as well. An E4#10 from Baker Hughes is modified for adaptive seat delivery.

摘要： A cut and pull spear is configured to obtain multiple grips in a tubular to be cut under tension. The slips are set mechanically with the aid of drag blocks to hold a portion of the assembly while a mandrel is manipulated. An annular seal is set in conjunction with the slips to provide well control during the cut. An internal bypass around the seal can be in the open position to allow circulation during the cut. The bypass can be closed to control a well kick with mechanical manipulation as the seal remains set. If the tubular will not release after an initial cut, the spear can be triggered to release and be reset at another location. The mandrel is open to circulation while the slips and seal are set and the cut is being made. Cuttings are filtered before entering the bypass to keep the cuttings out of the blowout preventers.
摘要翻译：切割和拉伸矛构造成在张力下获得要切割的管状体中的多个夹具。在操纵心轴的同时借助于阻力块机械地设置滑块以保持组件的一部分。环形密封件与滑块一起设置，以在切割期间提供良好的控制。围绕密封件的内部旁路可以处于打开位置，以允许在切割期间循环。当密封保持固定时，旁路可以通过机械操作来关闭以控制井膛。如果管道在初始切割后不会释放，则可以触发释放矛并在另一个位置重置矛。心轴打开循环，同时将滑块和密封件放置并切割。在进入旁路之前，将切屑过滤，以将切屑从防喷器中排出。

摘要： Methods and devices for controlling fluid flow into a wellbore tubular includes an in-flow control device, an element co-acting with the in-flow control device, and a disintegrating medium at least partially surrounding the element. The medium may be configured to release the element upon disintegration of the medium. The disintegrating medium may be configured to disintegrate when exposed to a selected fluid. The element may be configured to at least partially restrict flow across a flow path associated with the in-flow control device when released. The flow path may convey the fluid from the formation to a flow bore of the wellbore tubular and the element may be positioned along the flow path. The element may be: a liquid, a solid, a particle and/or particles. The selected fluid may be water, a hydrocarbon, an engineered fluid, and/or a naturally occurring fluid.
