It is plugged on the pin hole 1-1 and simulates shot point.
And survey line 5, the survey line 5, for drawing a circle to approve obstacles borders.Survey line 5 on panel 1 by being surrounded by default shape
Shape carrys out analog obstacle object.
Further, the panel 1 is made of the subpanel 1-2 of four pieces of same sizes, is spelled between the subpanel 1-2
It connects or is hinged.It is as a result, splicing or hinged between subpanel 1-2, subpanel 1-2 can fold up storage, panel 1 as a result,
It is convenient for carrying, is put in technical staff's knapsack as laptop, be carried to scene convenient for technical staff.The panel
1 can carry out size setting according to scale bar size (1:5000 or 1:1000), in addition, the number of the used subpanel 1-2 of selection
It can be four or four or more, particular number is scaled by corresponding proportion.
Further, the panel 1 and subpanel 1-2 are square.Four an equal amount of subpanel 1-2 are combined into one
A panel 1.
Further, the pin hole 1-1 is evenly distributed on panel 1.For grafting wave detector model 2 and shot point model 3.
Further, the pin hole 1-1 is arranged into an array, i.e. the uniform arrangement of the perpendicular column of row.
Further, the top of the wave detector model 2 is spherosome 2-1, and the lower part of the wave detector model 2 is first

Simulation system is seen in change based on 3-d seismic exploration of the invention, proposes a kind of analogy method, this method are as follows: is used
Panel 1 simulates area to be surveyed, and with the position for the profile simulation practical obstacle object that survey line 5 surrounds, is simulated with wave detector model 2
Wave detector on geophone station or geophone station simulates shot point with shot point model 3, by wave detector model 2 and shot point model 3 respectively according to
The plan of construction assigns on panel 1, and wave detector model 2 is measured relative to the distance scale 4 of shot point model 3, according to reality
Situation changes the relative position of wave detector model 2, shot point model 3 and survey line.
The following are explain in detail: as shown in figure 8, Inline directional spreding is geophone station in theoretic arrangement and method for construction,
Xline directional spreding is shot point, is uniform, regular laying.This is in order to which seismic wave energy passes to subsurface geological structure
Energy is uniform when upper, and azimuth is comprehensive, is all in this way 360 ° to the reflection at any point.But actual conditions
In, such as village barrier can be encountered, this just needs to carry out change sight, as shown in figure 9, big face has occurred in shot point, geophone station in figure
Long-pending movement, so after having drawn a circle to approve barrier range using survey line 5, one by one by within the scope of this shot point, geophone station is according to applying
Work specification carries out change sight, accomplishes not fall any one shot point, geophone station, meets workload demand.Then wave detector model 2 is used
Geophone station is simulated, shot point is simulated with shot point model 3, wave detector model 2 and shot point model 3 is assigned according to the plan of construction respectively
On panel 1.
Because seismic prospecting is split shooting, in order not to data white space occur, centered on shot point, village must be wrapped
It is contained within the scope of effect road number covers, just can overcome the disadvantages that village bring influences in this way, this is apart from just needing us to go to count
It calculates, calculating process is the prior art.Through calculating give a maximum distance, that is, maximum corresponding to valid trace number away from
From the corresponding total length to drift slide 4, is measured using scale, centered on shot point, as long as shooting distance village side in model
The distance on boundary is less than the 1/2 of this maximum distance, just illustrates our shot point connection and reasonable arrangement.
One cycle is reciprocal, one by one to needing the shot point for becoming sight to measure, until guaranteeing to become the degree of covering for seeing region
And physical points meet design requirement.
Model through the invention can be completed in a model, and without completing on computers, cost is substantially reduced, and one
The daily cost of labor of the seismic prospecting construction team of a 100 people or so is at 30,000 yuan or so, therefore raising construction efficiency can save
Very large project cost.When encountering special changes sight situation when previous construction, need to extract obstacle article coordinate and laid geophone station,
Shot point coordinate, pass back to processing center carry out simulation blow out, calculate become see after observation system coverage area.Then according to simulation
As a result arrangement and method for construction is improved.This process needs at least one working day, and time, economic cost are very big.Construction site
In mountain area, the unfrequented place such as desert does not use the condition of computer, and professional software is needed to be simulated, conventional pen
Note this without these softwares, so needing back and forth with processing center and scene, and answering for scene can not be fully described in telephonic communication
Miscellaneous situation.And the present invention is on panel 1 by assigning wave detector model 2 and shot point model 3, and it can be with ranging using scale 4, it can
The required precision of construction is fully met, and efficiency can be greatly improved, without being calculated back and forth with construction site and processing center
Machine simulation.
The change of 3-d seismic exploration sees simulation system the basic element spread of observation system on the same platform.It is theoretical
In the case of, geophone station in arrangement and method for construction, physical points are uniform, regular layings, but encountering has large-scale village, railway, river
Stream etc. needs to carry out change sight when being difficult to barrier evading, can not passing through, that is, transversely or longitudinally change geophone station,
Shot position, technical staff can draw a circle to approve obstacles borders according to the actual situation, flexibly change geophone station, shot position, and selection connects
Receive range.It can also be calculated using the statistics that Special ruler carries out degree of covering to barrier region.
Simulation system and method for the present invention can be more intuitive, more flexible, easily simulate to site operation situation, help
Technical staff takes out reasonable arrangement and method for construction in the shortest time.It can also play the role of teaching simultaneously, the system of being observed is set
Meter, improved teaching.
