MULTPLE PORT CROSS-OVER DESIGN FOR FRAC PACK EROSION MITIGATION

摘要

A system for use in gravel packing operations wherein a gravel placementmandrel (38) defines an axial flowbore (40) and two or more lateral slurry-flow ports (48) for communication of slurry from the flowbore to the interiorof the wear sleeve/blast liner (30). The slurry flow ports are oriented so asto distribute the slurry in different outwardly radial directions. The slurryflow ports are also axially offset from one another along the gravel placementmandrel body. Relatively equivalent flow rates or flow amounts are providedthrough each of the slurry flow ports. Improvements are also provided in thegeometry of the slurry flow ports to enhance the flow of slurry through them.
