ABSTRACT:
An inflation packer apparatus includes an inflatable packer bladder and uses cementitious fluid as an inflation fluid. The packer apparatus includes a packer mandrel having a central flow passage therethrough and an outer packer body which includes the inflatable packer bladder. A chemical accelerating agent is employed to accelerate the hardening time of the cementitious fluid used to inflate the packer bladder. An annular inflation fluid passageway is defined between the mandrel and the body. Inflation fluid passes from the central flow passage into the annular inflation fluid passageway to inflate the inflatable packer bladder. The mandrel has grooves defined on an outer surface thereof. The chemical accelerating agent is placed in grooves defined on the outer surface of the mandrel so that the accelerating agent is dispersed into the fluid passing into the annular passageway.
