WELL BORE TREATING FLUID TOOL Abstract of the Disclosure Relatively rotatable inner and outer tubular bodies include ports for communicating a well string in which the bodies are connected with the well bore. A seal between the bodies surrounds the port in one of the bodies to control communication between the bodies and well bore when the bodies are rotated to align and misalign the ports. A restrainer engages the well bore to restrain one of the bodies while the other is rotated by the well string and a receptacle with a port between seals that engage the well bore is provided so that a treating fluid placed in the well string may be pumped down while the body ports are open to discharge well string fluid to the well bore and when the treating fluid reaches the bodies, the ports are closed so the treating fluid may be discharged through the receptacle ports into the well bore zone isolated between the seals on the receptacle.
