Description
Technical field
The application is related to petroleum gas technical field, more particularly to a kind of surface structure survey method and apparatus.
Background technology
Seismic prospecting is to produce seismic wave by artificial excitation, is propagated by Study of Seismic ripple in the different stratum of elasticity
Rule carrys out the geological condition of exploring subsurface.The main process of seismic prospecting can be divided into three phases：Seismic data acquisition, earthquake
Data processing and seismic data interpretation, finally give geology result.
Seismic data acquisition is to produce seismic wave, such as using explosive as focus, ignition charge by artificial method
Seismic wave is produced, the earth shock signal caused by the seismic wave returned as subsurface reflective is then recorded with earthquake receiving instrument,
Corresponding log sheet is obtained by calculating processing.
During seismic data acquisition, in the range of certain depth, there is a kind of speed very low ground near near surface
Rotating fields, seismic wave by when can take more time, the stratum of this depth bounds is referred to as weathering zone.Some
, also there is a relatively low transition region of speed, referred to as reduction of speed band between weathering zone and hyper tape in area.Weathering zone, reduction of speed band
Speed and thickness change very big in machine and transverse direction, therefore seismic wave is also different by elapsed time during different layers band, this
Very big trouble can be brought to follow-up seism processing by planting temporal difference, such as be unable to in-phase stacking, and subsurface imaging is stranded
Difficulty etc..Therefore, to obtain that the seismic profile of underground truth can be reflected, must just eliminate shadow of the surface structure to seismic wave
Ring.
In order to eliminate influence of the surface structure to seismic wave, some physical parameters on top layer must be just grasped, including speed,
The situation of change about data spatially such as depth, lithology, this is referred to as surface structure survey in geological exploration techniques.

Position, seismograph record receives direct wave every time, and reads the first arrival time and observation speed of direct wave, whole through data
Reason, m- depth vertical time curve when making.Micro logging method is higher than little refraction method precision, but implements the people that micro logging is consumed
Power, material resources are huge, and cost occupies high, it is difficult to a large amount of to lay.
Artillery first arrival method is that the earthquake single-shot preliminary wave information obtained using conventional two-dimensional seismic survey chromatograph instead
The method drilled, the advantage is that depth of investigation is big, can reach hundreds of meters, its shortcoming is to be limited to larger track pitch, investigate
Limited precision.
