Description
Technical field
The present invention relates to geophysical exploration technology, more particularly, relate to the seismic signal receiving equipment the shallow water areas such as inland lake, river fast, efficiently, accurately the location technology.
Background technology
In the process of being explored at ocean, shallow sea and shoal area, the orientation problem technical method that solves the seismic signal receiving equipment mainly be take mathematic calculation as main, the sonar to measure localization method generally adopted and primary wave location mathematical method.The sonar to measure localization method is a kind of range positioning system, and primary wave location mathematical method is to determine the localization method of the accurate location of seismic signal receiving equipment in water by statistical study by the first break time of seismologic record.Because there is waters in the shallow water areas such as inland lake, river, disperse, the characteristics such as each water surface area little (cross over span and generally be no more than 1500 meters), used sonar to measure localization method cost too high; And primary wave location mathematical method need to have the data of more earthquake reception channel to participate in its computational accuracy of guarantee, the earthquake reception channel related in the little waters of area is usually all less, finally can cause computational accuracy not reach the accuracy of seismic exploration requirement.So above method commonly used all is not suitable for seismic prospecting or the microearthquake in the little waters of area.
Summary of the invention
The object of the invention is to overcome above and other shortcoming in the prior art.For this reason, the invention provides a kind of orientation problem solved fast, efficiently, accurately in seismic prospecting when the seismic signal receiving equipment is constructed in the waters of area little (cross over span and generally be no more than 1500 meters).
The localization method of seismic signal receiving equipment comprises according to an exemplary embodiment of the present invention: on wire rope, at interval of certain track pitch, mark; Be fixed on the two sides, waters along the seismic line direction by the wire rope of carrying out mark is stretching, be fixed on the wire rope mark using floating thing as buoy; The seismic signal receiving equipment is placed into to projected depth under water; Measure coordinate and the elevation of water surface float; According to the projected depth under water of earthquake signal receiver and the elevation of buoy, calculate the elevation of the seismic signal receiving equipment in water.
The characteristics of the localization method of seismic signal receiving equipment are easy operatings according to an exemplary embodiment of the present invention, and the speed of construction is fast, and cost is lower, and the advantage that precision is higher is applicable to the inland waters seismic prospecting that width is no more than 1500 meters.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is the schematic diagram of the localization method of seismic signal receiving equipment according to an exemplary embodiment of the present invention.
Embodiment
As shown in Figure 1, according to an exemplary embodiment of the present, the localization method of seismic signal receiving equipment comprises step described below according to an exemplary embodiment of the present invention.
(1) on wire rope, at interval of certain track pitch (as 30 meters intervals), mark.
(2) will carry out that the wire rope of mark is stretching is fixed on the two sides, waters along the seismic line direction, floating thing (such as tire) will be fixed on to the wire rope mark as buoy, complete water surface location.
(3) the seismic signal receiving equipment is placed into and buoy projected depth under water accordingly, to complete location under water.Wherein, described projected depth under water can be arranged according to the waters degree of depth.For example, can be for certain wire rope, will with buoy accordingly under water projected depth be defined as the same degree of depth, also can be defined as the different degree of depth from the corresponding projected depth under water of buoy.
(4) measure coordinate and the elevation of each buoy of the water surface.Here, in addition, the coordinate of other directions of seismic signal receiving equipment is identical with buoy except the coordinate of gravity direction different from corresponding buoy (that is to say; elevation is different between the two with corresponding seismic signal receiving equipment for buoy) for seismic signal receiving equipment in water.
(5), according to the elevation of the sinking degree of depth of earthquake signal receiver (also with buoy corresponding to this seismic signal receiving equipment projected depth under water accordingly) and buoy, calculate the elevation of the seismic signal receiving equipment in water.
H=H
0-L (formula 1)
In formula 1, the elevation that H is seismic signal receiving equipment in water, H
0for water level elevation, the sinking degree of depth that L is the seismic signal receiving equipment in water.
According to an exemplary embodiment of the present, provide a kind of orientation problem solved fast, efficiently, accurately in seismic prospecting when constructed in the seismic signal receiving equipment waters little at area.The characteristics of the localization method of seismic signal receiving equipment are easy operatings according to an exemplary embodiment of the present invention, and the speed of construction is fast, and cost is lower, and the advantage that precision is higher is applicable to the inland waters seismic prospecting that width is no more than 1500 meters.
