    摘要： A gravel pack operation disposes slurry from an inner string into the annulus around a shoe track. A valve on the shoe track can open and close flow through a port, and seats around the port allow an outlet of the tool to seal with the port. When the valve is open and the outlet sealed with the port, the slurry in the string is pumped into the borehole around the shoe track by flowing the slurry from the outlet into the borehole through the flow port. As this occurs, gravel collects around the shoe track, and fluid returns in the borehole flow back into the shoe track through a screen disposed toward the track's toe. Once inside the shoe track, the fluid returns communicate through a bypass on the shoe track around the sealed outlet and port. At this point, the fluid returns can pass uphole in the gravel pack assembly.

    摘要： A downhole assembly, such as a toe-to-heel gravel pack assembly, has a body with a body passage, outlet ports for slurry, and screens for fluid returns. An inner string deploys in the body to perform the toe-to-heel gravel packing. A telescoping adjustment device allows the inner string to space out properly when deployed to the toe of the assembly. Sealing surfaces or seats of a locating device in the body separate a sealable space and seal against seals on the inner string movably disposed therein. Fluid pumped in the string produces a pressure buildup when the string's port communicates with the sealable space. The pressure buildup indicates that the tool is positioned at a first location in the assembly, and other positions for placement of the tool can then be calculated therefrom.

    摘要： A crossover tool has an internal sleeve rotatably positioned within an external sleeve, and each of the sleeves has ports alignable with ports on the other sleeve. After deploying the crossover tool downhole and diverting fluid flow below the tool, fluid flow communicated into the internal sleeve tends to rotate it relative to the external sleeve until the ports are substantially aligned so that wear to the components is substantially reduced. The ports themselves may facilitate the rotation and alignment. For example, ports on the internal sleeve may produce tangentially exiting fluid flow. Alternatively, an additional outlet may be defined in the internal sleeve and eccentrically located to its rotation axis. Furthermore, an internal sleeve or insert may partially block fluid flow through the ports to allow greater fluid flow through the additional outlet to enhance rotation of the internal sleeve.

    摘要翻译： 交叉工具具有可旋转地定位在外部套筒内的内部套筒，并且每个套筒具有可与另一套筒上的端口对准的端口。 在井下布置交叉工具并将流体流动转移到工具下方之前，流入内部套筒的流体流动趋向于相对于外部套筒旋转，直到端口基本对准，使得部件的磨损显着降低。 端口本身可以促进旋转和对准。 例如，内部套筒上的端口可产生切向离开的流体流。 或者，可以在内部套筒中限定附加的出口，并且偏心地位于其旋转轴线上。 此外，内部套筒或插入件可以部分地阻塞流过端口的流体流动，以允许更大的流体流过附加出口以增强内部套筒的旋转。

    摘要： A configuration is provided to anchor the tubing string into a polished-bore receptacle while providing the ability to disconnect the tubing string from the polished-bore receptacle in a single trip in the wellbore. The configuration of the anchor provides for metal-to-metal sealing, and the disconnection is accomplished by a penetrating tool which accesses an annular cavity to unsupport locking dogs which facilitate removal of the tubing string from the polished-bore receptacle with applied pressure. If the packer needs to come out for any reason, a retrieving tool is described which, in a single trip, allows the retrieving tool to be advanced thru-tubing into the packer itself to unlock it. The retrieving tool is pulled out of the tubing and a pick-up force is applied to the tubing string to extend the packer to allow for its ultimate removal with the tubing.
