METHOD AND APPARATUS FOR POSITIONING AND REPOSITIONING A PLURALITY OF SERVICE TOOLS DOWNHOLE WITHOUT ROTATION

摘要

A method and apparatus is disclosed for downhole remediation. In the preferred embodiment, a bridge plug and service packer can be run into a wel l on coiled or rigid tubing. The assembly is capable of being set without rotation. The service packer is locked against setting until it is separated from t he bridge plug. Setting of the bridge plug closes a passage within it that had been open to facilitate circulation during run-in. The service packer is set with longitudinal movements using an indexing mechanism. At the conclusion of the procedure, the service packer is released and lowered to recapture th e bridge plug. The bridge plug is equalized and released to allow the assembly to be repositioned elsewhere in the wellbore or retrieved. The spacing betwe en the packer and bridge plug can be varied as desired.
