Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
In the prior art, due to insufficient equipment, part of projects have the condition, if partial arrangement of shot points in the external line receiving direction is abandoned, the whole line bundle can be constructed, but the range of a coverage frequency gradual reduction belt is reduced, the coverage frequency of different surface elements is reduced, and the requirements of project exploration are not met; due to the missing part of the collecting equipment, the whole wire harness can not be subjected to rolling construction. Under the condition of lacking of the collecting equipment, if rolling along the receiving line direction is adopted, in order to achieve the expected production efficiency, the paying-off efficiency can only be improved, the arrangement rolling is faster, more personnel are required to be arranged, and meanwhile, more transporting equipment is added to pour the collecting equipment from the back row to the front row; or the whole wire harness is constructed in a block mode, and more repeated arrangement needs to be laid among blocks in the block mode; both of these approaches undoubtedly increase costs. If gather and adopt the horizontal roll mode, want to alleviate unwrapping wire pressure, only invest more collection equipment, the reality can't allocate more equipment. Therefore, in this case, neither the conventional vertical scroll nor the lateral scroll can be implemented.
In order to solve the outstanding problem that the expected construction efficiency of three-dimensional acquisition cannot be achieved due to insufficient investment of acquisition equipment, an earthquake acquisition boundary optimization operation method is provided, namely, under the condition that the partial arrangement of the shot point in the external wire receiving direction is abandoned, the whole bundle construction can be carried out, and the requirement that the coverage times of the project requirement are gradually reduced and the coverage times are kept unchanged is met through the earthquake acquisition boundary optimization. The method effectively solves the problem that the construction efficiency cannot be ensured due to insufficient equipment investment.
As shown in fig. 15, in one aspect, the present invention provides a method for optimizing a seismic acquisition observation system, including:
s1: dividing the boundary of an original earthquake acquisition observation system into a first part and a second part, wherein the first part is an observation system with a full coverage boundary unchanged, and the second part is a receiving point to be optimized and a corresponding shot point;
s2: and rotating the shot-receiver points of the second part according to the symmetrical axis of the covering times, and combining the rotated second part and the first part to form the optimized seismic acquisition observation system.
The invention provides an optimization method of an earthquake acquisition observation system, which can optimize an excitation point and a receiving point at the boundary of the receiving line direction of a work area according to the content of the invention during earthquake acquisition, meet the requirement that the required coverage times are not changed when the coverage times are gradually reduced, and simultaneously solve the problem that the construction efficiency cannot be ensured due to insufficient equipment investment.
In certain embodiments, further comprising:
adjusting the line distance between the first part and the second part in the optimized seismic acquisition observation system to be the line distance between the first part and the second part in the original seismic acquisition observation system;
and simulating blasting by adopting the optimized template in the seismic acquisition observation system to generate a relation file.
In certain embodiments, further comprising:
and performing shot line retraction operation on the shot points in the optimized earthquake acquisition observation system, and increasing the receiving points with the shot line distance as a unit in the receiving lines containing the relationship when the shot points retract one shot line.
In certain embodiments, further comprising:
and performing shot line retraction operation on the shot points in the optimized earthquake acquisition observation system, wherein when one shot line is added to each shot point, the receiver points retract to the receiver points in the optimized part, and the receiver line retracts to the receiver points with the shot line distance as a unit.
It can be understood that, when the method is based on the conventional earthquake acquisition operation, part of receiving points in the external wire receiving direction of the shot point are abandoned aiming at the defects of acquisition equipment, and the wave detection point and the shot point outside the construction boundary of the shot point can be optimized under the condition of carrying out whole-wire bundle construction. The method can ensure that the data boundary before and after optimization is not changed, the range of the coverage time gradual reduction band is not reduced, the coverage time is not less than the coverage time before optimization, and the specific implementation conditions are as follows:
1) searching an optimization scheme that a coverage boundary does not change once and a full coverage boundary does not change, wherein the implementation of the step mainly comprises the following two steps of a) and b):
a) dividing the boundary of a conventional acquisition observation system into two parts, wherein one part is an observation system with a full coverage boundary unchanged, and the other part is a receiving point to be optimized and a corresponding shot point;
b) rotating the shot-geophone points of the other part of observation systems according to the symmetrical axis of the covering times; and combining the rotated observation system with the observation system with unchanged full coverage times. According to the combined scheme, multiple blasting devices and few placing devices are arranged at the boundary, so that the contradiction of insufficient receiving devices is solved, and the covering times of the original construction area are guaranteed to be unchanged.
2) Finding a general method to ensure that the position of a primary coverage boundary is not changed, the times of full coverage are not changed or an optimization scheme is added, and realizing the steps mainly comprises the following two steps:
c) for the two parts of the merging scheme in the step 1), the line distance between the two parts is adjusted to be consistent with the line distance of the original design observation system scheme, the shot point still uses the original template to simulate blasting to generate a relation file, after demonstration, the position of the primary coverage boundary is unchanged, the full coverage boundary is increased, and the optimization purpose is also achieved.
d) On the basis of the adjusted observation system, retracting the whole shot line of the shot point, increasing receiving points on the basis of the optimized part by the demodulator probe, and increasing the receiving points with the shot line distance as a unit by the receiving lines containing the relationship when the shot point retracts one shot line; or on the basis of the original observation system, when one shot line is added to each shot point, the receiving points are retracted in the optimized part by the demodulator probe, and when one shot line is added, the receiving points take the receiving line retraction shot line distance as a unit. The number of the gun lines is increased or retracted, and the number of the single-side receiving tracks is divided by (the gun line distance is divided by the receiving point distance) at most.
Specifically, an observation system template parameter is set: the 8L6S120T orthonormal template, where the receive line is 300 meters apart, the fire line is 300 meters apart, the receive point is 50 meters apart, and the fire point is 50 meters apart. The template of the observation system is shown in figure 1.
Rolling by using a set observation system template, wherein Inline rolls for 30 times and Xline rolls for 4 times; and covering the distributed observation system template for 40 times. As shown in fig. 2.
According to the laid observation system, one line spacing length is reserved outside the shot point at the boundary, namely 6 lines are reserved for each receiving line outside the shot point, and the gray part in the box is 11 intercepted detection lines. As shown in fig. 3.
Fig. 4 is a shot point distribution diagram of the remaining portion after cutting.
FIG. 5 is a diagram taken of 11 survey lines and associated shots.
Fig. 6 is a plot of the number of coverage of a receiver line, i.e., associated shot point, taken, which is found to be symmetrical, with the expression of the axis of symmetry in the vertical direction being:
Xleft1＝XR1+XS1；
Xright1＝XRN+XSM；
Xsymmetry＝(Xleft1+Xright1)/2
XR1horizontal coordinate of the leftmost receiver point, XS1As the horizontal coordinate of the leftmost shot point, Xleft1Horizontal coordinates of the leftmost one-time overlay; xRNIs the horizontal coordinate, X, of the rightmost receiving pointSMIs the horizontal coordinate of the rightmost shot point, Xright1Horizontal coordinates of the rightmost one-time coverage; xsymmetryThe average value of the left side primary coverage and the right side primary coverage is the symmetry axis of the intercepted part in the vertical direction.
And 7, intercepting a shot point distribution diagram after the shot points rotate 180 degrees around the symmetry axis, and combining the shot points (figure 4) of the rest part of the intercepted shot points and figure 7 to obtain a combined observation system (figure 8).
Fig. 9a and 9b show the coverage times of the original observation system and the coverage times of the boundary-optimized observation system, which are all 0 by performing a forward subtraction (fig. 9 c). Therefore, the purpose of optimizing the boundary is achieved, the requirement of the first party can be met by a method of more blasting (on the premise of high-efficiency acquisition) and less equipment placement, the contradiction of insufficient receiving equipment is solved, and the unchanged covering times of the original construction area are ensured.
According to the above theoretical basis, there are cases where:
after the shot-geophone points of the intercepted part are optimized and merged with the shot-geophone points of the rest part, the situation that the distance of the gun line is increased exists, as shown in figure 8.
And secondly, redundant equipment exists after optimization, and whether the optimized method can reduce part of shot points and increase part of receiving arrangement can still achieve the purpose of keeping the covering times unchanged or increasing.
Through the two parts of shot points and the corresponding arrangement pieces (fig. 10 and fig. 11) of the optimized observation system, the distance between the two parts of shot lines is increased by 150 meters, and the number of the wave detection points corresponding to the optimized part of shot points is still 3 unused reception points, so that further optimization is carried out, the distance between the shot lines at the combined joint is adjusted from 450 meters to 300 meters, and the number of the reception arrangement of the optimized part is increased by 3 (150 meters), as shown in fig. 12.
The coverage times of the adjusted observation system and the original observation system are subtracted, the coverage of one time is unchanged, the full coverage is increased, the coverage times are gradually decreased, and the coverage times are increased in a strip mode, as shown in fig. 13a to 13 c. The aim of unchanged or increased covering times is also achieved.
On the basis of the adjusted observation system, retracting the whole shot line of the shot point, increasing receiving points on the basis of the optimized part by the demodulator probe, wherein each time the shot point retracts one shot line, the receiving points increase the shot line distance as a unit; or on the basis of the original observation system, when one shot line is added to each shot point, the receiving points are retracted in the optimized part by the demodulator probe, and when one shot line is added, the receiving points take the receiving line retraction shot line distance as a unit. The number of gun lines is increased or retracted, at most the number of single receiver tracks divided by (gun line spacing divided by receiver dot spacing), see fig. 14.
It can be understood that the present invention has the following effects:
1) in the three-dimensional acquisition construction, by utilizing the boundary optimization of the invention, if the vibroseis is efficiently acquired, the construction can be carried out in a way of more blasting and less path swinging, and the investment of receiving equipment can be reduced;
2) in the three-dimensional acquisition construction, by utilizing the boundary optimization of the invention, if the well and gun excitation is carried out, the number of the excited guns can be properly optimized, the construction is carried out in a way of properly placing the number of tracks, and the excitation and receiving investment are balanced.

and the optimization module is used for rotating the shot-geophone points of the second part according to the symmetrical axis of the covering times and combining the rotated second part and the first part to form the optimized seismic acquisition observation system.
