Formation treatment system.

摘要

A treatment system including a first tubular having at least one port therein. A valve member is disposed with the first tubular and operatively arranged to control fluid flow through the at least one port. A second tubular is disposed radially within the first tubular and terminates at an end opening into an interior passage of the first tubular for enabling a treatment media to be supplied through the second tubular into the first tubular, and through the at least one port when the at least one port is open. A seal assembly is disposed between the first and second tubulars for fluidly sealing an annulus formed between the first and second tubulars from the end of the second tubular. A tool is disposed with the second tubular for controlling operation of the valve member.
