Problems solved by technology

[0002] At present, air gun boats are widely used as seismic excitation devices in offshore seismic exploration operations at home and abroad, and vibrators and well gun explosives are used as seismic excitation devices on land, but in the transition zone area between sea and land with a water depth of 0-1.5 meters Seismic excitation, neither land seismic sources nor sea air guns can be used
The use of explosives is also severely restricted or banned in many areas
[0003] Chinese patent ZL200610112522.6 discloses a mud gun seismic source used in areas with a water depth of 0-1.5m and soft ground such as silt swamps. However, this device is not suitable for hard ground such as sandy beaches or coral reefs. Equipment not reported

Abstract

The invention relates to a tidal and extremely-shallow water weight seismic source which is applicable to geophysical prospecting operation for petroleum. The tidal and extremely-shallow water weight seismic source comprises a buoyancy tank caterpillar swamp buggy and a weight seismic source, wherein the weight seismic source is arranged in the middle of the buoyancy tank caterpillar swamp buggy. A buoyancy tank caterpillar swamp buggy carrying chassis technology and a weight seismic source technology are integrated, the problem about seismic prospecting operation seismic source of a transitional zone with water depth of 0 to 1.5 m between the land and the sea is effectively solved, and the tidal and extremely-shallow water weight seismic source is high in operation reliability and facilitates environment protection of an operation region.

Description

technical field [0001] The invention relates to a beach and extremely shallow water weight hammer seismic source used in petroleum geophysical exploration operations, in particular to a beach and extremely shallow water weight hammer seismic source. Background technique [0002] At present, air gun boats are widely used as seismic excitation devices in offshore seismic exploration operations at home and abroad, and vibrators and well gun explosives are used as seismic excitation devices on land, but in the transition zone area between sea and land with a water depth of 0-1.5 meters Seismic excitation, land seismic sources, and sea air guns cannot be used. The use of explosives is also severely restricted or banned in many areas. [0003] Chinese patent ZL200610112522.6 discloses a mud gun seismic source used in areas with a water depth of 0-1.5m and soft ground such as silt swamps. However, this device is not suitable for hard ground such as sandy beaches or coral reefs. E...
