Vibrator suitable for marsh and mudflat operation

Technical Field

The utility model relates to a geophysical exploration technical field especially relates to a vibrator that is fit for marsh, mud flat operation.

Background

The manual excitation of seismic waves by a controllable seismic source is an important method for seismic exploration. The controllable seismic source has super-strong anti-interference capability, and because the signal frequency spectrum and the basic characteristics generated by the controllable seismic source can be manually controlled, certain interference frequency can be avoided when the scanning signal of the seismic source is designed, and the absorption effect of the stratum on the seismic signal can be compensated, which is difficult to realize by other artificial ground seismic sources and explosive seismic sources, the controllable seismic source can be used for seismic exploration to obtain the data with enough reflection energy, and the signal-to-noise ratio and the signal resolution can meet the geological exploration requirement. The method has the advantages of wide application field of seismic exploration, high precision, detailed layering, large detection depth and the like, and plays an important role in the general investigation of important resources such as petroleum, natural gas and coal.

The vibrator is a main working mechanism of the controllable seismic source, and the performance of the vibrator directly influences the performance of the controllable seismic source. The traditional vibroseis is often constructed on land with a hard earth surface or on sand and Gobi without settlement, and the vibrator does not have the problems of settlement, output reduction and the like in the vibration process. However, when constructing in the fields of marsh, mudflat and the like, the construction is useless, so a vibrator suitable for marsh and mudflat operation needs to be designed to solve the problems.
