Description

Technical Field

[0001] The invention relates to the field of geophysical exploration technology, and in particular to a method and a device for evaluating the uniformity of three-dimensional seismic shot point distribution. Background Art

[0002] This section is intended to provide a background or context to the embodiments of the invention recited in the claims. No admission is made that the description herein is prior art by inclusion in this section.

[0003] In the field of seismic exploration, due to the influence of ground obstacles, safety and other external factors, the correct layout of the seismic network is greatly affected during field acquisition. The excitation shot points are often not fired at the designed positions, resulting in frequent uneven distribution of shot points. The uniformity of the distribution of excitation shots directly affects the quality of pre-stack attributes and imaging of seismic data. At present, the evaluation of the uniformity of shot point distribution usually uses two indicators, "punctuality rate" and "acquisition footprint". The punctuality rate quantitatively analyzes the distance difference between the theoretical design coordinates and the measured coordinates of the same excitation shot point, thereby conducting a statistical evaluation of the points in the entire work area; the acquisition footprint can qualitatively analyze and evaluate the impact of shot inspection distribution on data quality from seismic data.

[0004] Among the above-mentioned shot point uniformity evaluation methods, the on-point rate evaluation method evaluates the degree of deviation of a single shot point from the theoretical position and evaluates the "point", which has a good effect on two-dimensional seismic, but cannot scientifically and effectively evaluate and assess three-dimensional seismic, especially high-density three-dimensional "surfaces"; the collection footprint evaluation method relies more on the evaluation of completed collection data, which has poor timeliness, and there are many factors that produce collection footprints, including uneven distribution of shot inspection points, rolling of three-dimensional arrangement sheets, terrain and surface structure. In short, the existing shot point uniformity evaluation methods cannot accurately and effectively realize the evaluation of the uniformity of three-dimensional seismic shot point distribution.

[0027] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0028] In order to solve the problem of quantitative evaluation of the uniformity of shot point distribution in a three-dimensional seismic work area, while meeting the requirements of rapid field acquisition and production, the uniformity of shot point distribution in a three-dimensional seismic work area is quantitatively evaluated and analyzed in real time, and the uneven blocks are quickly locked for rationality verification, eliminating the randomness of individual samples, so that the evaluation conclusion is more universal and objective; at the same time, it also provides very favorable basic data for quality managers to timely discover and rectify quality defects in the engineering process, thereby ensuring the high-quality and efficient completion of acquisition tasks. The embodiment of the present invention provides a three-dimensional seismic shot point distribution uniformity evaluation method, such as Figure 1 As shown, the method may include:

[0029] Step 101, dividing the shot point coverage area of ​​the three-dimensional seismic work area into a plurality of sub-areas of predetermined sizes;

[0030] Step 102, counting the number of theoretically designed shot points and the number of measured shot points in each sub-area, and calculating the uniformity value of each sub-area;

[0031] Step 103: According to a predetermined uniformity evaluation standard, the uniformity evaluation standard interval of the uniformity value of each sub-area is matched to obtain a uniformity evaluation conclusion of each sub-area;

[0032] Step 104: obtaining a uniformity evaluation conclusion of the three-dimensional seismic work area according to the uniformity evaluation conclusion of each sub-area;

[0033] Step 105: Calculate the uniformity value of the three-dimensional seismic work area according to the uniformity value of each sub-area.

[0034] Depend on Figure 1 It can be seen from the process shown that the embodiment of the present invention solves the current situation that traditional evaluation indicators cannot effectively evaluate the uniformity quality of shot points for three-dimensional seismic, especially high-density three-dimensional "surfaces"; the calculation is simple and fast, and only the theoretical design number of shot points and the measured number of shot points are required to achieve uniformity evaluation, which greatly improves timeliness, quickly and accurately locks uneven blocks, and gives the construction party more time to carry out quality rectification, which indirectly saves construction costs; the quantitative calculation of the uniformity value of the work area is effectively combined with the qualitative evaluation of the uniformity of the work area according to the uniformity evaluation standard, so that the quantitative evaluation conclusion is more universal and objective, the evaluation result is more intuitive, and it effectively guides the quality control work of shot point layout.

[0035] In specific implementation, the coverage of the shot points in the three-dimensional seismic work area is divided into a plurality of sub-areas of predetermined sizes. In an embodiment, the coverage of the shot points in the three-dimensional seismic work area can be divided into a plurality of sub-areas of predetermined areas, wherein each sub-area is a rectangle, with the shot line as the midpoint, and the width extending to the left and right by 1 / 2 of the shot line distance, and the ratio of the predetermined area to the width is the length. For example, the coverage of the shot points in the three-dimensional seismic work area can be divided into 1km 2 A sub-area, the sub-area is rectangular, with the gun line as the midpoint, and the width extending 1 / 2 of the gun line distance on both sides, 1km 2 The ratio of length to width is given by formula (1):

[0036]

[0037] Among them, Shot_module is the shot point distribution sub-area within one square kilometer, and SLI is the shot line distance.

[0038] After dividing the shot point coverage of the three-dimensional seismic work area into multiple sub-areas of predetermined size, the number of theoretically designed shot points and the number of measured shot points in each sub-area are counted to calculate the uniformity value of each sub-area. In the embodiment, the uniformity value of each sub-area can be calculated according to formula (2):

[0039]

[0040] Among them, Shot_Evenness n is the uniformity value of the sub-area, A shot is the number of measured shot points in the sub-area, B shot The number of theoretically designed shot points in the sub-area.

[0041] After the uniformity value of each sub-area is calculated, the uniformity evaluation standard interval in which the uniformity value of each sub-area is located can be matched according to a predetermined uniformity evaluation standard to obtain a uniformity evaluation conclusion of each sub-area. In an embodiment, when the uniformity value of the sub-area is greater than or equal to the first set value and less than or equal to the second set value, the uniformity evaluation conclusion of the sub-area can be determined as uniform; when the uniformity value of the sub-area is less than the first set value and greater than or equal to the third set value, or greater than the second set value and less than or equal to the fourth set value, the uniformity evaluation conclusion of the sub-area can be determined as relatively uniform; when the uniformity value of the sub-area is less than the third set value, or greater than the fourth set value, the uniformity evaluation conclusion of the sub-area can be determined as non-uniform.

[0042] For example, the uniformity evaluation standard can be predefined as: when the uniformity value of the sub-area is greater than or equal to 0.8 and less than or equal to 1.2, the uniformity evaluation conclusion of the sub-area is uniform; when the uniformity value of the sub-area is less than 0.8 and greater than or equal to 0.5, or greater than 1.2 and less than or equal to 1.5, the uniformity evaluation conclusion of the sub-area is relatively uniform; when the uniformity value of the sub-area is less than 0.5, or greater than 1.5, the uniformity evaluation conclusion of the sub-area is uneven.

[0043] After obtaining the uniformity evaluation conclusion of each sub-area, the uniformity evaluation conclusion of the three-dimensional seismic work area can be obtained according to the uniformity evaluation conclusion of each sub-area. In an embodiment, each sub-area can be spread on the survey network of the three-dimensional seismic work area; each sub-area spread on the survey network is assigned a value according to the uniformity value of each sub-area; and the uniformity evaluation conclusion of each sub-area is displayed in a corresponding expression form for each sub-area spread on the survey network. Among them, the expression form of sub-areas with different uniformity can be filled with different colors, for example, the sub-area with a uniform uniformity evaluation conclusion is filled with green; the sub-area with a relatively uniform uniform uniformity evaluation conclusion is filled with yellow; and the sub-area with an uneven uniform uniform uniformity evaluation conclusion is filled with red. Alternatively, the expression form can also be filled with different lines, shapes, grayscales, annotated, and other specific forms. It is easy for those skilled in the art to understand that it is only necessary to show the difference in uniformity of the sub-areas.

[0044] After calculating the uniformity value of each sub-area, the uniformity value of the three-dimensional seismic work area can also be calculated based on the uniformity value of each sub-area. In the embodiment, the uniformity value of the three-dimensional seismic work area can be calculated based on the uniformity value of each sub-area according to formula (3):

[0045]

[0046] Wherein, E is the uniformity value of the three-dimensional seismic work area, x is the uniformity value of the sub-area, and n is the number of sub-areas.

[0047] The following is a specific example to illustrate the method for evaluating the uniformity of three-dimensional seismic shot point distribution according to an embodiment of the present invention. Figure 2 As shown, in this example, the specific implementation may include:

[0049] Step 202: Divide the coverage area of ​​the three-dimensional seismic work area into 1km 2 A sub-area (such as Figure 3 The sub-area is a rectangle, with the gun line as the midpoint and the width extending 1 / 2 of the gun line distance on both sides, 1km2 The ratio of the length to the width is the length. The calculation method is shown in formula (1). The number of theoretical design shot points and the number of measured shot points in each sub-area are counted.

[0050]

[0051] Among them, Shot_module is the shot point distribution sub-area within one square kilometer, and SLI is the shot line distance.

[0052] Step 203: The shot point distribution sub-areas calculated in the work area are numbered according to the shot line number + sub-area sequence number (numbered in order from small to large according to the shot point pile number), and the uniformity value of each sub-area is calculated according to formula (2).

[0053]

[0054] Among them, Shot_Evenness n is the uniformity value of the sub-area, A shot is the number of measured shot points in the sub-area, B shot The number of theoretically designed shot points in the sub-area.

[0055] Step 204, establish a uniformity evaluation standard, a uniformity value greater than or equal to 0.8 and less than or equal to 1.2 is defined as uniform; a uniformity value less than 0.8 and greater than or equal to 0.5, or greater than 1.2 and less than or equal to 1.5 is defined as relatively uniform; a uniformity value greater than 1.5 or less than 0.5 is defined as uneven (such as Figure 4 shown).

[0056] Step 205: spread the sub-areas in step 202 on the work area measurement network, assign values ​​according to the calculation results in step 203, and fill in the evaluation criteria in step 204 (such as Figure 5 At the same time, the overall uniformity of the work area is quantitatively calculated using formula (3) to achieve quantitative evaluation of the uniformity of the shot point distribution.

[0057]

[0058] Wherein, E is the uniformity value of the three-dimensional seismic work area, x is the uniformity value of the sub-area, and n is the number of sub-areas.

[0059] Step 206: Combined with high-definition satellite images or obstacle interference information, quality assessment is performed on uneven blocks and contiguous relatively uniform blocks, and quality rectification is prompted for uneven blocks caused by non-obstacle-crossing design.
