DOWN HOLE FLUID HEATING APPARATUS AND METHOD

摘要

An apparatus for providing heat energy to a fluid, including a housing adapted for connection into a working string and for inserting into a borehole, a flow path for the fluid extending within the housing, a pressure drop device positioned within the flow path, and an actuator for actuating the apparatus between a minimum pressure drop position and a maximum pressure drop position. A method for providing heat energy to a fluid, including the steps of providing an apparatus in a borehole, actuating the apparatus to a maximum pressure drop position, and circulating the fluid through a pressure drop device which is positioned within a flow path in the apparatus.
