Description

Technical Field

[0001] The invention relates to the technical field of seismic exploration and development, and in particular to a surface element attribute evaluation method and device. Background Art

[0002] In the process of oil and gas exploration and development, the design of a three-dimensional observation system is the first step in the whole process of seismic data acquisition. As the geological targets in the exploration area become increasingly complex, many observation system design schemes are often proposed for a certain geological task during the design of the observation system. However, each scheme is not very different in the macro sense, and it is difficult to measure the quality of an observation system attribute with the naked eye. How to establish a set of quantitative observation system attribute evaluation methods has become a focus of designers.

[0003] Traditional design software mainly provides coverage frequency distribution diagram, offset distribution diagram, rose diagram, etc. Among them, the coverage frequency distribution diagram can be used to describe the distribution of different coverage times in the observation system scheme. Through this distribution diagram, we can understand the proportion and distribution of different coverage times in the observation system scheme. The offset distribution diagram is used to describe the distribution of different offsets in the observation system scheme. The offset refers to the distance between the excitation source and the receiving station in seismic exploration. The distribution of the offset will affect the quality and resolution of the seismic signal. The rose diagram is used to describe the relative relationship between different azimuths and receiving points in the observation system scheme. In seismic exploration, the azimuth refers to the angle between the direction of seismic wave propagation and a certain reference direction, and the receiving point is a device for receiving seismic waves. The rose diagram can better understand the coverage of the observation system and the relationship between different azimuths and receiving points. However, these presentation methods can only provide users with visual results, and cannot provide users with quantitative evaluation of the scheme. Therefore, it is expected to propose a quantitative evaluation method for the design of a three-dimensional observation system. Summary of the invention

[0054] Figure 4 A Simpson coefficient distribution graph and a histogram obtained according to an exemplary embodiment of the present invention are shown. DETAILED DESCRIPTION

[0055] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0056] The present invention provides a facet attribute evaluation method, comprising the following steps:

[0057] Step 1: Determine n distance segments so that the intervals between each distance segment are equal;

[0058] Step 2: For each bin of the seismic data, store the offset data in the bin into an offset array;

[0059] Step 3: For each bin, count the number of offset data contained in each distance segment;

[0060] Step 4: Calculate the Simpson coefficient of each bin according to the number of offset data;

[0061] Step 5: Generate a Simpson coefficient distribution graph and a histogram based on the Simpson coefficient of each facet.

[0062] The bin attribute evaluation method of the present invention performs bin attribute evaluation based on the Simpson coefficient, and can quantitatively evaluate the probability of occurrence of intra-bin offsets in different ranges, thus providing a more effective analysis method for acquisition designers.

[0063] Example 1

[0064] Figure 1 The flowchart of the facet attribute evaluation method according to an embodiment of the present invention is shown. As shown in the figure, the method includes steps 1 to 5.

[0065] Step 1: Determine n distance segments so that the intervals between each distance segment are equal.

[0066] According to the requirements of analysis accuracy, the shot offset is divided into multiple distance segments. That is, n distance segments are determined so that the intervals between each distance segment are equal. For example, 10 distance segments are determined with an interval of 500 meters, so the shot offset data can be processed within the distance range of 0 to 5000 meters.

[0067] Step 2: For each bin of seismic data, store the offset data within the bin into an offset array.

[0068] In the field of geophysical exploration, an elementary cell refers to a small area in space, usually used to describe a sampling unit or grid unit in seismic exploration data. In three-dimensional seismic exploration, an elementary cell is usually a cubic unit, and its size and shape depend on the sampling density and observation system design.

[0069] The choice of bins has a significant impact on the resolution and quality of seismic data. Smaller bins provide higher resolution but may also introduce more noise and discontinuities. Larger bins provide smoother data but may also sacrifice some resolution.

[0070] When processing seismic data, the size and shape of the bins can be adjusted according to actual needs. For example, in the inversion process, smaller bins can be used to improve resolution, while in filtering or smoothing, larger bins can be used to reduce noise interference.

[0071] For each bin of seismic data, the offset data in the bin is stored in the offset array. Specifically, storing the offset data in the bin in the offset array includes:

[0072] Sort the offset data in the bin from small to large;

[0073] Store the sorted offset data into the offset array offset i Where i represents the offset array i The subscript of , i∈{0,1,2...,m}, m represents the amount of data in the offset array.

[0074] After the above processing, the offset data in each bin is stored in an offset array, and in each offset array, the offset data are arranged in ascending order, so as to prepare for the subsequent counting of the number of offset data contained in each distance segment.

[0075] Step 3: For each bin, count the number of offset data contained in each distance segment.

[0076] The number of offset data included in each distance segment is counted as follows:

[0077] Create an offset count array bin j , bin the offset count array j The initial value of each data is set to zero;

[0078] For each data in the offset array, calculate Bin the offset count array j The value of the jth data is added by 1, where j represents the gun offset count array bin j The subscript of , j∈{0,1,2...,n}, space represents the interval between each distance segment.

[0079] The offset count array is used to reflect the number of offset data contained in each distance segment. Since the offset data have been arranged in ascending order in the previous step, according to the formula The calculated j value indicates which data (i.e., which distance segment) of the offset count array the offset data corresponds to. j The value of the jth data is added by 1, and the number of offset data in the distance segment is accumulated. The above operation is performed for each data in the offset array, and the number of offset data contained in each distance segment can be counted.

[0080] Step 4: Calculate the Simpson coefficient of each bin based on the number of offset data.

[0081] The Simpson coefficient is a statistical indicator used to measure the degree of overall difference, also known as the Simpson coefficient of difference. The Simpson coefficient of a facet can be used to measure the uniformity of the distribution of individuals within the facet. If the distribution of individuals within the facet is more uniform, the Simpson coefficient is closer to 0; if the distribution of individuals within the facet is more uneven, the Simpson coefficient is closer to 1.

[0082] Specifically, the Simpson coefficient of each facet is calculated according to the following formula:

[0083]

[0084] Among them, Dk represents the Simpson coefficient of the kth face element, N k It represents the number of offset data contained in the kth bin.

[0085] Step 5: Generate a Simpson coefficient distribution graph and a histogram based on the Simpson coefficient of each facet.

[0086] Generating a Simpson coefficient distribution graph based on the Simpson coefficient of each facet includes:

[0087] A color scale axis in the range of [0,1] is established, and the Simpson coefficient of each facet is correspondingly depicted in a two-dimensional space based on the color scale axis to generate a distribution grid map, that is, a Simpson coefficient distribution map.

[0088] The color scale axis uses color to indicate the size of the Simpson coefficient. The Simpson coefficient distribution diagram generated based on the color scale axis can more intuitively show the distribution of the Simpson coefficient, thereby providing a more effective analysis method for acquisition designers.

[0089] Generating a Simpson coefficient histogram based on the Simpson coefficient of each bin includes:

[0090] Define multiple Simpson coefficient ranges and count the number of facets corresponding to each Simpson coefficient range;

[0091] The horizontal axis represents the range of each Simpson coefficient, and the vertical axis represents the number of bins corresponding to the Simpson coefficient range, thereby generating a Simpson coefficient histogram.

[0092] The Simpson coefficient histogram can intuitively show the number of facets corresponding to each Simpson coefficient range.

[0098] Step 4: Calculate the Simpson coefficient of each bin according to the number of offset data;

[0099] Step 5: Generate a Simpson coefficient distribution graph and a histogram based on the Simpson coefficient of each facet.

[0104] Create an offset count array bin j , bin the offset count array j The initial value of each data is set to zero;

[0106] In this embodiment, the Simpson coefficient of each bin is calculated according to the following formula:

[0107]

[0108] Among them, D k represents the Simpson coefficient of the kth face element, N k It represents the number of offset data contained in the kth bin.

[0109] In this embodiment, generating a Simpson coefficient distribution graph according to the Simpson coefficient of each bin includes:

[0110] A color scale axis in the range of [0,1] is established, and the Simpson coefficient of each facet is depicted in two-dimensional space based on the color scale axis to generate a distribution grid map, namely, the Simpson coefficient distribution map.

[0111] In this embodiment, generating a Simpson coefficient histogram according to the Simpson coefficient of each bin includes:

[0112] Define multiple Simpson coefficient ranges and count the number of facets corresponding to each Simpson coefficient range;

[0113] The horizontal axis represents the range of each Simpson coefficient, and the vertical axis represents the number of bins corresponding to the Simpson coefficient range, thereby generating a Simpson coefficient histogram.
