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： A gravel pack assembly has a longitudinal body that disposes in a borehole. A wellscreen and other components can connect to the body to complete the assembly. One or more packoff seals or bushings disposed in the body's inner passage can engage a smooth external surface of a crossover tool when disposed therein. This sealing prevents passage of sand and fluids between the tool and the assembly's inner passage. Moreover, the smooth external surface makes the tool less likely of becoming stuck in the inner passage. The packoff seals or bushings can be fixed or activated by movement to engage the smooth external surface of the crossover tool.

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 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 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.
