摘要： Devices for controlling the flow of fluids past a location in a wellbore and methods for using such devices are disclosed. Embodiment devices are configured such that the throughbore is maximized because of the devices' thin cross sectional length. Embodiment devices may be optimized to expand into larger casing sizes by use of a multi-part cone system while maintaining the thin cross section. Embodiment devices may also permit the plug to be communicated into the well with the flow control devices, reducing the fluid volume required to treat well stages separated by the disclosed embodiment devices.
摘要翻译：公开了用于控制流体穿过井眼中的位置的装置以及使用这种装置的方法。由于器件的薄横截面长度，实施例器件被配置成使通孔最大化。可以通过使用多部分锥体系统来优化实施例装置以扩展到较大的套管尺寸，同时保持薄的横截面。实施例装置还可以允许插头与流量控制装置一起传送到井中，从而减少由公开的实施例装置分离的处理井段所需的流体体积。

摘要： An apparatus installs downhole in a surrounding tubular. A first shoulder on a mandrel of the apparatus is movable toward a second shoulder. A plurality of stacked rings are disposed about the mandrel and are spaced between the first and second shoulders. A first of the stacked rings decreases in spacing in response to the movement of the first shoulder toward the second shoulder, and a second of the stacked rings expands outward from the mandrel in response to the decrease in spacing. A slip disposed on the stacked rings is movable away from the mandrel toward the surrounding tubular in response to the outward expansion. The apparatus can be a plug, a bridge plug, a fracture plug, a packer, a permanent packer, a retrievable packer, a sump packer, and a sealbore packer. Additionally, the apparatus can include a completion assembly with packer and screen supported on the mandrel.

摘要： An expandable seal has at least one travel stop designed to engage the surrounding tubular to limit expansion of the ring shape of the seal and in so doing limit the stress of circumferential ribs that extend from the ring base shape as they engage the surrounding tubular. The travel stop can be a solid ring or segments and can have a rounded outer surface designed to engage the surrounding tubular in a flush relationship. Alternatively the outer surface can also have hardened particles for a bite into the wall of the surrounding tubular before the blunt portions of the travel stop come into contact with the inside wall of the surrounding tubular.

摘要： Certain aspects are directed to a device designed to relieve compression in a length of pipe. The device provides a load ring that can absorb and isolate load until a shear sleeve is shifted and shear pins are sheared. A specific aspect provides a packer release compaction joint that has a shifting sleeve having a first internal shoulder configured to engage a shifting tool; a shear sleeve having a raised abutment; a load ring mounted on the shear sleeve, the load ring having an outer diameter and positioned forward of the first side of the raised abutment; a snap ring mounted around the outer diameter of the load ring. Action of a shifting tool against the first internal shoulder of the shifting sleeve causes the snap ring to move away from the load ring and move to the second side of the raised abutment.
