Description
Technical field
The present invention relates to the intelligent control composite coherent electric sparks that marine engineering geology is used.
Background technology
Offshore seismic is surveyed focus and is comprised air gun (Air gun), hydraulic giant focus (Watergun), sparker source (Sparker) and transducer focus (Boomer transducer) etc.The at present domestic sparker source of generally using has the Geo-Spark series etc. of the Geo-Resources company research and development of SIG series that French S.I.G company produces and Holland.In the oceanographic engineering seismic prospecting, sparker source is the most frequently used focus, by changing the emitted energy of sparker source, can obtain the seismic section of different penetration depths and corresponding resolution.Sparker source is wide with its spectral range, the resolution height, and characteristics such as easy to use are used widely in offshore shooting.
Because the frequency of the seismic signal of macro-energy is low, the stratum penetration capacity is strong, but resolution is low, and the frequency height of the seismic signal of little energy, the resolution height, but the stratum penetration capacity is limited.In a detection process, can only use the focus of certain energy to survey because of prior art again, obtain the seismic section of a kind of corresponding penetration depth and resolution, reduce exploration efficiency.For solving the contradiction of focus between the stratum detecting degree of depth and resolution characteristic.Therefore use a cover focus alternately to launch high and low two kinds of seismic signals that energy is different, use two different hydrophone cables of dominant frequency to receive simultaneously, in detection process, not only can obtain the shallow section data and but also can obtain the mid-deep strata seismic data, improving exploration efficiency, is the demand of economic construction and scientific research.
In addition, second pressure pulse of the source wavelet of sparker source is the obstacle that further improves the sparker source stratigraphic resolution always, causes thin strate disappearance or smudgy in the seismic section data that receives.
Summary of the invention
The purpose of this invention is to provide a kind of source signal of alternately launching the different dominant frequency of two kinds of different-energies, can obtain the intelligent control composite coherent electric sparks of the bigger mid-deep strata seismic data of high-resolution shallow seismic profile data and penetration depth in succession respectively, to remedy the deficiency of prior art.
Another object of the present invention is influence or the interference of second pressure pulse of reduction or the source wavelet that overcomes sparker source to stratigraphic resolution, to improve stratigraphic resolution
