The utility model relates to a fireflooding stratified electric ignition technological string. The technological string is arranged in an oil well with a first oil layer on the upper portion and a second oil layer on the lower portion and comprises an inner pipe and an outer pipe, the inner pipe is located in the outer pipe, and an annular space is formed between the inner pipe and the outer pipe; the outer pipe comprises an external oil pipe and a screen pipe located at the position corresponding to the first oil layer, a first packer and a second packer are arranged on the outer pipe, the first packer is located above the first oil layer, and the second packer is located between the first oil layer and the second oil layer; the inner pipe comprises an internal oil pipe and a slide sleeve air distributing device connected with the internal oil pipe, and the slide sleeve air distributing device is located at the position corresponding to the first oil layer; the portion, located below the second packer, of the inner pipe and the portion, located below the second packer, of the outer pipe are connected with a sliding sealing device capable of sealing the annular space. The success rate of stratified ignition is increased, fine gas injection is achieved, and the problem that downhole measuring and adjusting instruments cannot work normally in a high-temperature state is avoided.
