The utility model discloses a water mixing companion heat facility, it relates to oil gas exploitation technical field, water mixing companion heat facility includes: the top connection, top connection inside has the intercommunication the first runner of top connection upper end and lower extreme, top connection inside has the intercommunication the top connection lower extreme with the second runner of top connection lateral wall, the connection is in the overcoat of top connection lower extreme, the setting is in traveling valve in the overcoat, the traveling valve with the second runner is linked together with control the switching of second runner. The utility model provides a water mixing companion heat facility can effectively solve when high pour -point oil oil recovery in -process lifts the temperature because of the pit shaft and reduce the card well phenomenon that viscosity rose and leads to the fact, has still avoided simultaneously hindering great problem because of empty core rod's the complicated circulation that leads to the fact of structure rubs.
