摘要: In the representative embodiment of invention described herein, formation-treating apparatus is adapted to be dependently supported in a well bore from pipe string and which includes upper lower telescoped body members selectively moved between operating positions for controlling injection treating fluids into one or more earth formations traversed by bore. A pair spaced packer elements are mounted on member above below discharge port cooperatively arranged isolating interval that treated discharging port. To control fluids, retrievable valve means also within alternatively seated full-bore seats bodies response movement their positions. this manner, whenever its positions, will seat unseated open fluid communication tool. On other hand, position, trap any unused
