The present invention relates to the field of oilfield thermal recovery, and provides a gas-fired multi-component thermal fluid thermal recovery apparatus for an oilfield. The apparatus comprises an ignition assembly, a gas inlet assembly, a water inlet assembly, and a preheating assembly. The ignition assembly comprises a combustion cylinder, a mounting housing and an injection pipe which are fixed as one piece, wherein an igniter and a gas nozzle are fixedly mounted at a rear portion of the combustion cylinder, and the gas nozzle allows for the creation of a mixture of gas and air with a circular motion trajectory. The water inlet assembly comprises a water inlet plate fixedly mounted on the combustion cylinder, wherein the water inlet plate is fixedly connected to a water-containing housing, a plurality of water nozzles are mounted on the water-containing housing, and the water nozzles allow for the creation of water mist in a direction opposite the direction in which the gas nozzle sprays the gas. By means of providing the ignition assembly and the water inlet assembly, water vapor and the mixture of air and gas in opposite rotation directions can impinge against each other, thereby achieving a good mixing effect and ensuring the uniformity of the multi-component thermal fluid.
