The utility model provides a processing apparatus of SAGD well. This processing apparatus includes at least one sub - processing apparatus, and sub - processing apparatus includes stock solution equipment and liquid conveying pipeline, and stock solution equipment is stored there is liquid medium, the one end of liquid conveying pipeline is connected with stock solution equipment, and the other end of liquid conveying pipeline is connected with the first end of well head. Among the the device, the liquid medium in with stock solution equipment carries to the well head through the liquid conveying pipeline, and then through in the long oil pipe access silo in the well, just can make in the short time during some liquid medium get into the oil reservoir, and liquid is crowded in the realization to the porosity and the permeability of oil reservoir have been improved, and can realize the intercommunication between well and the well within a short period of time.
