Description
Technical Field
The invention relates to the field of geophysical exploration, in particular to a method, a system and a device for monitoring a controllable seismic source combination center in real time.
Background
This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.
In a seismic acquisition project constructed by using a controllable seismic source, the conventional real-time quality control method for the combined central coordinate of the seismic source is mainly based on two ideas: one method is based on the thought of shot offset analysis, and the deviation condition between the actual seismic source combination center position and the theoretical design seismic source combination center position is detected through a linear dynamic correction method or a method for comparing the theoretical first arrival with an automatic pickup first arrival; and secondly, based on the idea of information comparison of a seismic acquisition instrument database, acquiring the actual coordinates of the seismic source combination center from the database of the seismic acquisition instrument host, acquiring the theoretical coordinates of the seismic source combination center from the SPS (semi-persistent scheduling) used in field production, and calculating the distance between the actual coordinates and the theoretical coordinates, thereby detecting the deviation condition of the actual seismic source combination center position relative to the theoretical seismic source combination center position. The real-time quality control method for the elevation of the seismic source combination center is realized by comparing the elevation of the seismic source combination center acquired from a seismic acquisition instrument host database with the elevation of the seismic source combination center stored in the SPS.
For the real-time quality control method of the seismic source combination center coordinate based on the first thought, the method of linear dynamic correction is adopted to monitor the shot offset, and actually, the method is a means of performing shot offset detection by using the single-shot record first arrival of linear dynamic correction through manual observation. The method cannot realize complete automatic monitoring, and high labor consumption is required. On one hand, the requirement on the precision of the first arrival automatic picking method is very high, and on the other hand, for a single cannon with weak energy or serious noise interference, an ideal first arrival automatic picking effect cannot be obtained usually, so that a cannon offset monitoring result has a high misjudgment rate. For the real-time quality control method of the seismic source combination center coordinate and elevation based on the second idea, a database interface of a seismic acquisition instrument host must be acquired, and actually, database information of a plurality of instrument hosts, or the interface is not open to the outside, or there is time delay in information generation, or the process of information analysis is complicated, so that a large development workload is caused, which brings great difficulty to the real-time quality control of the seismic source combination center.

The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.

Reference to the description of the terms "one embodiment," "a particular embodiment," "some embodiments," "for example," etc., means that a particular feature, structure, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the application. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. The sequence of steps involved in the embodiments is for illustrative purposes to illustrate the implementation of the present application, and the sequence of steps is not limited and can be adjusted as needed.
In the actual earthquake acquisition production process, the over-limit of the central coordinates or the elevation of the earthquake focus combination belongs to the production quality problem, and the gun supplement is needed. In order to timely carry out shot repairing on shot points with over-limit coordinates or elevations of a seismic source combination center and avoid economic loss caused to production, the embodiment of the invention provides a real-time monitoring method for the controllable seismic source combination center, which can be applied but not limited in the high-density pile-number-free seismic acquisition operation process.
Fig. 1 is a flowchart of a method for monitoring a vibroseis combination center in real time according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
s101, acquiring gun line number information, shot point number information, coordinate information and elevation information of a seismic source combination center of actual blasting according to seismic single-shot data channel head information generated on site.
It should be noted that, for the seismic acquisition operation without pile numbers, in the controllable seismic source blasting process, the actual coordinate and elevation information of the seismic source combination center may be transmitted to the seismic data acquisition equipment through a radio station or a network, and the seismic data acquisition equipment may record the actual coordinate and elevation information of the seismic source combination center into the heading information of the original single-shot data when generating the original single-shot data, so that the information such as the line number, the shot point number, the coordinate, the elevation and the like of the seismic source combination center that is actually blasted may be directly obtained according to the heading information of the seismic single-shot data generated by the field seismic data acquisition equipment.
And S102, searching theoretical coordinate information and minimum offset detection point elevation information corresponding to the seismic source combination center from seismic exploration SPS information used for on-site production based on the shot line number information and the shot point number information of the seismic source combination center.
It should be noted that after acquiring the shot line number information and the shot point number information of the seismic source combination center from the seismic single-shot data track header information generated in the field through S101, theoretical coordinate information corresponding to the seismic source combination center may be searched from the seismic exploration SPS information used in the field production through S102 based on the shot line number information and the shot point number information of the seismic source combination center, so as to determine whether the coordinate of the seismic source combination center exceeds the limit according to the actual coordinate information and the corresponding theoretical coordinate information of the seismic source combination center.
For high-density pile-number-free seismic acquisition operation, because the theoretical point position of a shot point is not measured in advance under the pile-number-free operation condition, the elevation of a seismic source combination center cannot be preset in seismic exploration SPS information used for on-site production, and a mode of comparing the actual elevation and the theoretical elevation of the seismic source combination center cannot be adopted to monitor whether the elevation of the seismic source combination center exceeds the limit or not.
However, because the densities of the shot points and the demodulator probes are very high in the high-density seismic acquisition operation mode, many shot points and the demodulator probes with the minimum shot-geophone distance (the demodulator probes closest to the shot points) are very close to each other, and are often only a few meters away, and because the elevations of all the demodulator probes are measured, the elevations of all the demodulator probes can be preset in the seismic exploration SPS information used for field production. Therefore, in the embodiment of the invention, the minimum offset geophone point elevation information corresponding to the seismic source combination center is searched from the seismic exploration SPS information used for on-site production through the S102, and whether the elevation of the seismic source combination center exceeds the limit is monitored by comparing the actual elevation of the seismic source combination center with the elevation of the minimum offset geophone point.
In order to avoid measurement errors caused by excessively large distance between the shot point and the demodulator probe, the distance between the actual point position of the seismic source combination center and the demodulator probe is required to be not more than the specified distance between the shot point and the demodulator probe in the embodiment of the invention. Therefore, as an optional implementation manner, before determining whether the elevation of the seismic source combination center exceeds the limit according to the actual elevation information of the seismic source combination center and the elevation information of the corresponding minimum offset receiver point, the method for monitoring the vibroseis combination center in real time provided by the embodiment of the present invention may further include the following steps: searching the coordinate information of the minimum shot-geophone distance demodulator probes corresponding to the seismic source combination center from the seismic exploration SPS information used in field production based on the shot line number information and the shot point number information of the seismic source combination center; calculating the actual shot-geophone point distance according to the actual coordinate information of the seismic source combination center and the corresponding minimum shot-geophone distance geophone point coordinate information; and judging whether the actual shot-detecting point distance is less than or equal to the preset shot-detecting point distance or not, wherein under the condition that the actual shot-detecting point distance is less than or equal to the preset shot-detecting point distance, determining whether the elevation of the seismic source combination center exceeds the limit or not according to the actual elevation information of the seismic source combination center and the corresponding elevation information of the minimum shot-detecting distance detection point.
S103a, determining whether the coordinates of the center of the seismic source combination exceed the limit or not according to the actual coordinate information of the center of the seismic source combination and the corresponding theoretical coordinate information.
As an optional implementation manner, the step S103a may specifically include the following steps: calculating the distance between the actual coordinate of the seismic source combination center and the corresponding theoretical coordinate; judging whether the distance is larger than a preset distance error allowable value or not; if the distance is larger than a preset distance error allowable value, determining that the coordinate of the seismic source combination center exceeds the limit; and if the distance is less than or equal to the preset distance error allowable value, determining that the coordinates of the combined centers of the seismic sources are not exceeded.
S103b, determining whether the elevation of the seismic source combination center exceeds the limit or not according to the actual elevation information of the seismic source combination center and the corresponding elevation information of the minimum offset detection point.
As an optional implementation manner, the step S103b may specifically include the following steps: calculating the difference between the actual elevation of the seismic source combination center and the elevation of the corresponding minimum offset detection point; judging whether the difference value is larger than a preset elevation error allowable value or not; if the difference value is larger than a preset elevation error allowable value, determining that the elevation of the seismic source combination center exceeds the limit; and if the difference value is less than or equal to the preset elevation error allowable value, determining that the elevation of the seismic source combination center does not exceed the limit.
As can be seen from the above, the method for monitoring the vibroseis combination center in real time provided by the embodiment of the invention obtains the coordinate information and the elevation information of the actually shot vibroseis combination center from the seismic single-shot data track head information generated in real time on site, obtains the theoretical coordinate information of the vibroseis combination center and the elevation information of the minimum shot-geophone offset detection point from the seismic exploration SPS information used for on-site production based on the gun line number information and the gun point number information obtained from the seismic single-shot data track head information, and determines whether the coordinate of the vibroseis combination center exceeds the limit according to the actual coordinate information of the vibroseis combination center and the corresponding theoretical coordinate information; and determining whether the elevation of the seismic source combination center exceeds the limit or not according to the actual elevation information of the seismic source combination center and the corresponding elevation information of the minimum offset detection point so as to achieve the purpose of performing real-time quality control on the seismic source combination center for actual production blasting.
By the aid of the method and the device, the situation that the coordinates or the elevation of the seismic source combination center exceeds the limit in the construction process can be accurately and timely found, operators are timely reminded of repairing damaged guns caused by the seismic source combination center problem, and accordingly field construction quality and production efficiency are improved.
The real-time monitoring of the central coordinates or the elevations of the seismic source combination aims at finding the shot points with the central coordinates or the elevations exceeding the limits of the seismic source combination, and further reminding operators to carry out shot supplement on the shot points exceeding the limits. Therefore, in order to enable an operator to find a shot point with an over-limit of the coordinates or the elevation of the combined center of the seismic sources in time, an optional embodiment of the method for monitoring the combined center of the seismic sources in real time provided by the embodiment of the invention may further include the following steps: if the fact that the coordinate of the seismic source combination center exceeds the limit is determined, outputting first alarm information, wherein the first alarm information is used for prompting that the coordinate of the seismic source combination center exceeds the limit; and if the elevation of the seismic source combination center is determined to be out of limit, outputting second alarm information, wherein the second alarm information is used for prompting that the elevation of the seismic source combination center is out of limit.
As a preferred implementation manner, fig. 2 is a flowchart of a preferred real-time monitoring method for coordinates and elevation of a vibroseis combination center provided in an embodiment of the present invention, and may be suitable for real-time quality control of a vibroseis combination center in a vibroseis high-efficiency high-density pile-number-free seismic acquisition operation manner. As shown in fig. 2, the specific implementation process of the method includes the following steps:
s201, acquiring coordinates, elevations, gun line numbers and point numbers of the seismic source combination center of actual blasting according to the seismic single-shot data channel head information generated on site.

Therefore, for the real-time quality control system for seismic acquisition, the east coordinate S of the seismic source combination center of actual blasting is obtained by directly reading the original seismic single-shot data channel head information which is pushed to the real-time quality control host by the seismic data acquisition instrument host in real time X North coordinate S Y Elevation S Z Information such as the gun line number SL and the point number SP.

As can be seen from the above, according to the method for monitoring the seismic source combination center in real time for the controllable seismic source high-efficiency high-density pile-number-free acquisition operation mode provided by the embodiment of the invention, on one hand, the distance between the actual point location and the theoretical point location of the seismic source combination center of the seismic source is calculated by using the actual coordinate information of the seismic source combination center in the original single-shot data header information and the theoretical coordinate information of the seismic source combination center in the seismic exploration SPS information used for field production, so as to evaluate whether the coordinate of the seismic source combination center is out of limit, and the purpose of monitoring the central coordinate of the seismic source combination center in actual production in real time can be achieved; on the other hand, the actual elevation information of the seismic source combination center in the original single-shot data track head information and the elevation information of the minimum offset detection point in the seismic exploration SPS information used for on-site production are utilized to evaluate whether the elevation of the seismic source combination center exceeds the limit or not, and the purpose of monitoring the elevation of the seismic source combination center in actual production in real time can be achieved.
