Technical Field

Background
The near-surface medium is directly influenced by the atmospheric environment or the water environment in lithologic characteristics, bedding characteristics, cementation degree, speed parameters, density parameters and the like, and has the characteristic of uneven distribution.

Detailed Description
The embodiment of the specification provides a method and a device for constructing a near-surface structure model, so that various known near-surface structure models are utilized to perform fusion processing, and the characteristics of each near-surface structure model are integrated to obtain a new near-surface structure model.
The present specification will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.
Fig. 1 is a flowchart of a method for constructing a near-surface structure model according to an embodiment. As shown in fig. 1, the method provided by the present embodiment includes steps S101-S103.
S101: and acquiring the near-surface structure data of a plurality of near-surface structure models to be fused.
In a specific application, the multiple near-surface structure models to be fused can be at least two of a micro-logging near-surface structure model, a small-track-distance near-chromatography ground-surface structure model, a cannon chromatography near-surface structure model, a shallow reflection ground-surface structure model and a geological radar ground-surface structure model; that is, two or three known near-surface structure models are employed as the near-surface structure models to be fused, and corresponding near-surface structure data are acquired, respectively. The aforementioned near-surface structure data includes position coordinate data in addition to characteristic near-surface structure feature data such as amplitude.
In this embodiment, the first three near-surface structure models are all used as the near-surface structure model to be fused.
In practical applications, because the near-surface structure model may be characterized by using continuous data, the process of obtaining the near-surface structure data of the near-surface structure model to be fused may be a process of performing discrete datamation on the near-surface structure model to be fused. In specific application, the data volume of the discrete datamation data is determined according to the precision of a fusion near-surface structure model which is constructed according to needs, and the processing speed and the processing capacity of processing equipment.
S102: and acquiring the weighting parameters of the near-surface structure models to be fused in the coordinate interval.
Because different near-surface structure models have different accuracies in different coordinate intervals, different coordinate intervals are assigned with different weighting parameters for each near-surface structure model to be fused.
For example, in lateral accuracy, the accuracy of the micro-log near-surface structure model increases with distance from the logging point; in the aspect of longitudinal precision, the precision of the micro-logging near-surface structure model is reduced along with the increase of the well depth, so that the weighting parameter of the micro-logging near-surface structure model can be reduced along with the increase of the distance and the increase of the depth by taking the position of the logging point as the center.
Correspondingly, the precision difference of the small track distance near-surface structure model and the cannon chromatography near-surface structure model is not large; in order to keep the sum of the weighting coefficients of the data to be 1 all the time, the weighting parameters of the short-path near-surface structure model and the cannon chromatography near-surface structure model can be increased along with the increase of the distance and the increase of the depth by taking the position of the logging point as the center.
S103: and performing weighted calculation on the near-surface structure data of the corresponding coordinate interval according to the weighted parameters of each near-surface structure model to be fused in each coordinate interval to obtain a fused near-surface structure model.
After the near-surface structure data of each near-surface structure model to be fused and the weighting parameters of each near-surface structure model to be fused in different coordinate intervals are determined, the weighting parameters of the corresponding coordinate intervals and the near-surface structure data can be weighted and averaged to obtain fused near-surface structure data, and the fused near-surface structure model is constructed by adopting the fused near-surface structure model data.
According to the analysis of the steps, as the precision of each near-surface structure model to be fused in different coordinate intervals is different, the weighting parameters corresponding to the different coordinate intervals are different; and in the coordinate interval with better precision of the near-surface structure model to be fused, the corresponding weighting parameter value is larger. Therefore, the near-surface structure data obtained through weighted summation calculation fully integrates the advantages of different near-surface structure models, so that the near-surface description of the fused near-surface structure model is closer to the real situation.
Fig. 2 is a flow chart of a method of constructing a near-surface structure model provided herein. As shown in FIG. 2, in one embodiment, the foregoing method includes steps S201-S204.
S201: and acquiring the near-surface structure data of a plurality of near-surface structure models to be fused.
The multiple near-surface structure models to be fused can be at least two of a micro-logging near-surface structure model, a small-track-distance near-surface structure model and a cannon chromatography near-surface structure model.
In practical applications, because the near-surface structure model may be characterized by using continuous data, the process of obtaining the near-surface structure data of the near-surface structure model to be fused may be a process of performing discrete datamation on the near-surface structure model to be fused. In specific application, the data volume of the discrete datamation data is determined according to the precision of a fusion near-surface structure model which is constructed according to needs, and the processing speed and the processing capacity of processing equipment.
S202: and acquiring the transverse weighting parameters and the longitudinal weighting parameters of each near-surface structure model to be fused in the coordinate interval.
The horizontal weighting parameter is a weighting parameter in the horizontal plane direction, and the vertical weighting parameter is a weighting parameter in the depth direction.
Because the precision of the micro-logging near-surface structure model gradually decreases with increasing distance from the logging location, the lateral weighting parameters of the micro-logging near-surface structure model can be made to decrease with increasing distance from the logging location. For example, in one application, the lateral weighting parameter of the micro-logging near-surface structure model is 0.9 within 100m from the logging position, and the lateral weighting parameter of the corresponding interval is reduced by 0.1 with every 100m increase of the distance; conversely, the transverse weighting parameters of the small track distance near-surface structure model and the cannon chromatography near-surface structure model within a range of 100m from the logging position can be 0.05, and the transverse weighting parameters of the corresponding coordinate intervals are respectively increased by 0.05 with every 100m increase of the distance.
Because the precision of the micro-logging near-surface structure model is gradually reduced along with the increase of the logging depth, the longitudinal weighting parameter of the micro-logging near-surface structure model can be reduced along with the increase of the distance from the surface position. For example, in one application, the longitudinal weighting parameter for the micro-log near-surface structure model is set to 0.8 at a depth of 0-15m near the surface, 0.3 at a depth of 15-40m near the surface, and 0.05 at a depth exceeding 40m near the surface. Correspondingly, at the depth of 0-15m near the earth's surface, the longitudinal weighting parameter of the small track distance near-earth surface structure model is 0.15, and the longitudinal weighting parameter of the cannon chromatography near-earth surface structure model is 0.05; at the depth of 15-40m near the earth's surface, the longitudinal weighting parameter of the small track distance near-earth surface structure model is 0.6, and the longitudinal weighting parameter of the cannon chromatography near-earth surface structure model is 0.1; and when the depth from the earth surface exceeds 40m, the longitudinal weighting parameter of the small track distance near-earth surface structure model is 0.3, and the longitudinal weighting parameter of the cannon chromatography near-earth surface structure model is 0.65.
It should be noted that the weighting parameters are data obtained by comprehensively analyzing the characteristics of various near-surface structure models, and are not arbitrarily assigned. In areas with different near-surface features, the weight coefficients of different near-surface structure models to be fused are changed, and the specific weight coefficients are determined according to experience and field data.
S203: according to the transverse weighting parameters of each near-surface structure model to be fused in each coordinate interval, carrying out weighting calculation on the near-surface structure data of the corresponding coordinate interval to obtain transverse weighting data, and according to the longitudinal weighting parameters of each near-surface structure model to be fused in each coordinate interval, carrying out weighting calculation on the near-surface structure data of the corresponding coordinate interval to obtain longitudinal weighting data.
Step S203 is a process of performing horizontal weighting calculation on the near-surface structure feature data to be fused in the corresponding coordinate interval by using the determined horizontal weighting parameter, and performing vertical weighting calculation on the near-surface structure data to be fused in the corresponding coordinate interval by using the determined vertical weighting parameter.
For example, for a 100m range of logging positions, the transverse weighted data X is 0.8 × a +0.1 × B +0.1 × C, and the longitudinal weighted data Y is 0.8 × a +0.15 × B +0.05 × C, where a is the micro-logging near-surface structure data, B is the short-track-distance near-surface structure data, and C is the cannon-shot-tomography near-surface structure data.
S204: and carrying out equal-weight weighted average on the transverse weighted data and the longitudinal weighted data to obtain the fused near-surface structure model.
Step S204 is a process of re-fusing the horizontal weighting data and the vertical weighting data, and the specific fused near-surface structure data Z is 0.5 × (X + Y); and then, configuring all the fused near-surface structure data according to the coordinate interval, so as to form a fused near-surface structure model.
According to the process description, the fused near-surface structure model integrates the characteristics of various near-surface structure models to be fused, so that the near-surface structure characteristics can be better described.
In the foregoing embodiment, the horizontal weighting parameter and the vertical weighting parameter are respectively set, the data in different near-surface structure models are respectively weighted and averaged by using the horizontal weighting parameter and the vertical weighting parameter, and then the horizontal weighting data and the vertical weighting data obtained by the two weighting methods are averaged. In other embodiments, weighting parameters reflecting three-dimensional features may be set for each near-surface structure model to be fused, and the near-surface structure feature data may be obtained by directly using the three-dimensional feature weighting parameters to form a fused near-surface structure model.
In practical applications, the weighting parameters of each near-surface structure model to be fused in the coordinate interval may be input by an engineer or obtained by calling a stored weight-coordinate interval mapping table, and the embodiment of this specification is not particularly limited.
Based on the same inventive concept, the embodiments of the present disclosure further provide an apparatus for constructing a near-surface structure model, which can be used to implement the method described in the above embodiments, such as the following embodiments. Because the principle of solving the problem of the device for constructing the near-surface structure model is similar to that of the method, the specific method of the device for processing the seismic data can be referred to the content of the method, and repeated parts are not described again. As used hereinafter, the term "unit" or "module" may be a combination of software and/or hardware that implements a predetermined function. While the system described in the embodiments below is preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

As shown in fig. 3, the apparatus for constructing a near-surface structure model includes a model data obtaining module 11 to be fused, a weighting parameter obtaining module 12 and a fusion model calculating module 13.
The model data acquisition module to be fused 11 is used for acquiring near-surface structure data of various near-surface structure models to be fused; the multiple near-surface structure models to be fused comprise at least two of a micro-logging near-surface structure model, a small-track-distance chromatography ground surface structure model, a cannon chromatography ground surface structure model, a shallow reflection ground surface structure model and a geological radar ground surface structure model; the weighting parameter obtaining module 12 is configured to obtain weighting parameters of the to-be-fused near-surface structure models in the coordinate interval; and the fusion model calculation module 13 is configured to perform weighted calculation on the near-surface structure data in the corresponding coordinate interval according to the weighted parameters of each to-be-fused near-surface structure model in each coordinate interval, so as to obtain a fusion near-surface structure model.
Because the precision of each near-surface structure model to be fused in different coordinate intervals is different, the weighting parameters corresponding to different coordinate intervals are different. In addition, in a coordinate interval with good precision of the near-surface structure model to be fused, the corresponding weighting parameter value is large, so that the advantages of different near-surface structure models are fully fused by the near-surface structure data obtained through weighting summation calculation, and the near-surface depiction of the fused near-surface structure model to the near-surface is closer to the real condition.
In a specific application, the weighting parameter obtaining module 12 obtains a horizontal weighting parameter and a vertical weighting parameter of each to-be-fused near-surface structure model in a coordinate interval.

The transverse weighting calculation unit 131 performs weighting calculation on the near-surface structure data of the corresponding coordinate interval according to the transverse weighting parameter of each near-surface structure model to be fused in each coordinate interval to obtain transverse weighting data; the longitudinal weighting calculation unit 132 performs weighting calculation on the near-surface structure data of the corresponding coordinate interval according to the longitudinal weighting parameters of each near-surface structure model to be fused in each coordinate interval to obtain longitudinal weighting data; the equal weight calculation unit 133 performs equal weight weighted average on the horizontal weighted data and the vertical weighted data to obtain the fused near-surface structure model.
In a specific application, the weighting parameter obtaining module 12 obtains weighting parameters corresponding to all coordinate intervals by querying a pre-stored weight-coordinate interval mapping table; the data acquisition module to be fused acquires the corresponding near-surface structure data by performing discrete sampling on the near-surface structure model to be fused.
