Combined ultra-shallow steam gun vibration source system and process method

The invention discloses a combined ultra-shallow steam gun vibration source system and a process method, and belongs to the technical field of geophysical exploration. The combined ultra-shallow steam gun vibration source system consists of a buoyancy tank platform, a four-track structure, a lifting vertical column, a drilling machine, a winch, a propeller, a cab, a host machine, an air compressor, a lifting rod, a swinging arm, a rubber air bag, an air gun and a steel wire rope, wherein the buoyancy tank platform can be decomposed longitudinally, and satisfies the condition of road transportation after decomposition; the buoyancy tank platform has a dual-layer bottom structure, and the height of the structure is flush with the lifting vertical column; the buoyancy tank platform is connected with the four-track structure through the lifting vertical column; land and seabed walking can be realized through the four-track structure, and hydraulic sailing can be realized through the propeller, thereby realizing the combination of two kinds of walking mechanisms. The combined ultra-shallow steam gun vibration source system has the advantages that by adopting an assembled structure, two walking modes, namely, track walking and floating sailing can be realized, and two operation modes of borehole excitation and back trailing water excitation can be realized.
