Screen Pipe is usually made from a drill collar and with drilled holes. Slotted Tail Pipe is used for casing testing of single-packer. It hangs below the packer, and Slotted externally. Slotted Tail Pipe has a perforated strainer tube inside. The sizes of holes and slots are very small no matter they are holes drilled on the Screen or slots milled on the Slotted Tail Pipe, in such a manner, the mud cake or debris particles taking in the fluid are blocked out of tools, to avoid blocking tester valve, mandrel channels of tools and bottom-hole choke.In addition, we can manufacture heavy weight Slotted Tail Pipe according to customersrequirements.
