ABSTRACT:
Apparatus for interconnecting a tubing string with downhole tool and for controlling the flow of fluid into a wellbore through the tubing string comprising an elongated body member and a resiliently deformable sleeve disposed around the body member and radially deformable to form a seal against the wellbore wall to seal off a zone of interest. The body member includes a passage for extension of a wireline cable from the tubing string to the downhole tool. An electric motor operated rotary plug valve is disposed in the apparatus body and is operable to be rotated to valve pressure fluid from the tubing string into an expansible chamber to cause the seal sleeve to deform to seal the wellbore. The valve member is movable to positions to relieve pressure fluid from the seal, to valve pressure fluid to the wellbore at an injection point below the seal and to block all ports. A lower head member of the apparatus includes an anchor for the wireline cable sheath and an upper head member includes a check valve to prevent backflow of fluids from the wellbore into the tubing string.
