摘要： A well production apparatus includes a tubular production conduit which extends from the top of the well to a production zone interior of casing. An electric submersible pump has a production fluid flow passageway which communicates between the exterior of the conduit and the interior of the casing. A packer is in communication with the production conduit below the pump and is movable into sealing engagement with the casing to isolate the production zone. A thermal absorber is carried on the production conduit between upper and lower production conduit members whereby subsequent to positioning of the packer assembly into set position, thermal expansion or contraction of the conduit above the set packer is absorbed by the thermal absorber without transmission of thermal expansion or contraction of the conduit to the pump.
