Description

TECHNICAL FIELD

[0001] The present application relates to a gradual filling color linkage modification method and device changing with contour. BACKGROUND

[0002] In the field of oil and gas exploration and development, the exploration and exploitation of oil and gas resources is a highly complex and technology-intensive work, the core of which is to accurately identify and locate the underground stratum structure rich in oil and gas. Oil and gas reservoirs are rich in the crevice or structure of a specific rock layer in the underground. Modern oil and gas exploration and development needs to use contour maps to determine the location, depth, and shape of the target stratum, and to design well sites and calculate reserves. Therefore, it is of great significance to quickly and accurately determine the underground stratum structure and fault spatial characteristics through contour maps.

[0003] As a classic and powerful visualization tool, contour maps play an indispensable role in modern oil and gas exploration. By drawing a series of lines connecting the same attribute values (such as depth, rock layer top or bottom elevation) on a map or profile, the three-dimensional structure of the underground stratum is intuitively displayed. With the color gradient filling technology, contour maps can more finely display the continuity, thickness variation and structure fluctuation of the stratum, enabling geologists and engineers to intuitively understand the details of complex geological structures, including but not limited to stratum inclination, fault strike and dip, and closure height.

[0004] In modern digital oilfield management, contour maps are combined with GIS (Geographic Information System) and three-dimensional visualization software to realize dynamic interactive analysis of exploration data, enabling decision-makers to adjust exploration strategies in real time and optimize development plans. The application of this integrated technology greatly improves exploration efficiency, reduces drilling risks, and promotes sustainable development of underground oil and gas resources.

[0063] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be accurately conveyed to those skilled in the art.

[0064] The inventor found that in the prior art, by using related software, it is no longer necessary for the draftsmen to manually redraw and fill the contours, which saves a lot of time, but these software are relatively weak in the contour modification function, which not only has a complex operation, but also needs to be repeatedly edited, thereby leading to a cumbersome process. In particular, frequent changes to the contour chart not only cause the file size to expand, but also can cause the system to run slowly and even cause file damage, which undoubtedly increases unnecessary obstacles and time costs for research work. Based on this, the inventor has made the present application through further research and development, and provides a linkage modification method and device with the filling color changing with the contour.

[0065] Embodiment one

[0066] In the embodiment one of the present application, a linkage modification method with the filling color changing with the contour is provided, referring to the figure, the method can include the following steps S101-S105: Figure 1

[0067] S101: Obtain a contour chart to be processed; the contour chart to be processed includes a plurality of original filling color ranges and a plurality of updated contours.

[0068] S102: For each updated contour, based on the plurality of original filling color ranges, obtain two adjacent filling color ranges of the updated contour.

[0069] S103: For each adjacent filling color range, according to the updated contour and the adjacent filling color range, obtain a plurality of cutting ranges and two endpoints of each cutting range.

[0070] S104: For each cutting range, determine a reference point according to the two endpoints of the cutting range.

[0071] ​S105: According to the reference point, the adjacent filling color range is changed using the cutting range to obtain an updated filling color range.

[0072] The filling color linkage modification method provided by the embodiment of the present application can modify the filling color range according to the original filling color range in the to-be-processed contour map and a plurality of updated contours, determine a plurality of cutting ranges and two endpoints of each cutting range, and determine a reference point according to the two endpoints, thereby modifying the filling color range. The method uses a series of logical and reasonable structures to achieve the modification of the filling color range, intelligently modifies the filling color range in the to-be-processed contour map according to the updated contour, avoids the data redundancy and errors that may be caused by the traditional contour modification method, maintains the consistency and accuracy of the information in the contour map, can conveniently and efficiently complete the updating and improvement of the contour map, effectively simplifies the work process, improves the work efficiency, and enables the geologists to respond to the data changes more quickly, update the geological model in time, and speed up the exploration decision-making process.

[0073] The filling color linkage modification method provided by the embodiment of the present application can dynamically match the filling color in the contour map with the contour, make the overall performance of the contour map stronger, and make the presentation of the geological features more distinct and prominent. This not only improves the quality of the report and the display, but also provides more powerful support for scientific research communication and project decision-making.

[0074] In the step S101, the to-be-processed contour map can be obtained by the following method, specifically including the following steps S1011-S1013:

[0075] S1011: Obtain an original contour map.

[0076] Exemplarily, the original contour map is as shown in FIG. 1, including a plurality of original filling color ranges and a plurality of original contours, and each original filling color range and original contour has a corresponding value. Figure 2

[0077] Specifically, Figure 2 The value corresponding to the leftmost original filling color range in FIG. 1 is 30, indicating that the values corresponding to all points in the original filling color range are greater than or equal to 30. The black curve to the right of the original filling color range is the original contour corresponding to the value 30, indicating that the values corresponding to all points on the original contour are 30. The original filling color ranges and original contours corresponding to the values 20, 10 and 0 from left to right are sequentially arranged, and the original contour corresponding to the value 0 is a closed ring. The inside of the ring represents the original filling color range with the value-10, indicating that the values corresponding to all points in the original filling color range are between 0 and-10.

[0078] ​The values in the above examples are only examples, and therefore the units of the values are not specified. The actual contour map will have different values and units according to the requirements. For example, if the contour map shows the altitude, the unit is meter or foot.

[0079] Meanwhile, since the method does not include processing of the values, the values will not be described below.

[0080] S1012: updating the plurality of original contours according to the plurality of update data to obtain a plurality of update contours.

[0081] In the embodiment of the application, the plurality of update data obtained generally includes a plurality of discrete points and a value corresponding to each point. Therefore, when the original contour is updated using the update data in step S1012, a smooth curve is fitted according to the original contour and the update data as the update contour.

[0082] The method of fitting the curve can be implemented by those skilled in the art according to the detailed description of the prior art, such as smoothing filtering, and the embodiment of the application can not be specifically limited.

[0083] S1013: obtaining a to-be-processed contour map according to the plurality of update contours and the plurality of original fill color ranges.

[0084] Exemplarily, the to-be-processed contour map obtained according to the original contour map of Figure 2 is shown in Figure 3 It can be seen that the leftmost update contour and the original fill color ranges on both sides have two places where they do not fit, and other update contours also have some places where they do not fit with the original fill color ranges on both sides. Therefore, the original fill color range needs to be modified so that the fill color range fits the update contour.

[0085] In step S102, for each update contour, the original fill color ranges on both sides of the update contour in the plurality of original fill color ranges are taken as adjacent fill color ranges. For example, the to-be-processed contour map shown in Figure 3 The original fill colors on both sides of the leftmost update contour are the original fill colors corresponding to the update contour, and the original fill colors outside and inside the right lower annular update contour are the original fill colors corresponding to the update contour.

[0086] In step S103, the update contour includes a plurality of nodes with sequential numbers. For each adjacent fill color range, all nodes in the update contour are traversed to determine the places where the update contour and the adjacent fill color range do not fit, and the cutting range and two end points of each cutting range are obtained. Specifically, steps S1031-S1035 are included:

[0087] S1031: Search and update nodes in the contour lines in numerical order, and take the first node that is not on the edge of the adjacent fill color range as the split node.

[0088] S1032: Use the node preceding the split node as the first endpoint.

[0089] S1033: Take the first node that is on the edge of the adjacent fill color range after splitting the node as the second endpoint.

[0090] S1034: Determine the boundary based on the two endpoints, and use the area enclosed by the edge line of the adjacent fill color range and the updated contour line as the cutting range.

[0091] S1035: Starting from the second endpoint, continue executing the steps described above for searching and updating nodes in the contour lines in numerical order until the search for all nodes in the contour lines is completed, resulting in multiple cutting ranges and the two endpoints of each cutting range.

[0092] When searching for and updating nodes in the contour lines in order of their numbers in steps S1031 and S1035 above, the search can be performed in ascending order or descending order of their numbers.

[0093] For example, the multiple cutting ranges in the updated contour lines obtained in step S103 are as follows: Figure 4 As shown, the diagram includes two cutting ranges, f1 and f2. The two endpoints of cutting range f1 are a1 and b1, and the two endpoints of cutting range f2 are a2 and b2. The corresponding filling points in the diagram correspond to the adjacent filling color ranges mentioned above, the contour lines correspond to the updated contour lines mentioned above, and the contour line nodes correspond to the nodes in the updated contour lines mentioned above.

[0094] In step S104 above, the reference point is determined based on the two endpoints of each cutting range and the updated contour lines, specifically including the following steps S1041-S1043:

[0095] S1041: For each cutting range, connect the two endpoints of the cutting range to obtain a cutting line segment, and take the midpoint of the cutting line segment as the first intersection point.

[0096] S1042: Draw a perpendicular line to the cutting line segment based on the first intersection point, and take the intersection point of the perpendicular line and the updated contour line as the second intersection point.

[0097] S1043: Use the midpoint between the first intersection point and the second intersection point as the reference point.

[0098] by Figure 5 and Figure 6 Taking the cutting range shown as an example, according to Figure 5 The diagram showing the cutting range and corresponding endpoints obtained through step S104 is as follows:Figure 7 As shown in FIG. 6, according to the method of the present application, the cutting range and the corresponding end points are obtained by step S104, and the reference point is shown in FIG. 7. Figure 6 As shown in FIG. 7, the reference point is not in the cutting range, so step S1053 is executed, and the updated filling color range is obtained by adding the cutting range to the adjacent filling color range, as shown in FIG. 8. Figure 8 As shown in FIG. 7, Figure 7 and Figure 8 respectively show two different cutting cases formed by the updated contour and the adjacent filling color range, where a and b are two end points of the cutting range, the cutting line segment ab is obtained by connecting the two end points, the first intersection point c is the midpoint of the cutting line segment ab, the second intersection point d is obtained by drawing a perpendicular line of the cutting line segment ab based on the first intersection point c, and the reference point e is the midpoint of the first intersection point c and the second intersection point d.

[0099] In the embodiments of the present application, due to the diversity of the updated data, there is no fixed rule for the shape of the cutting range, and the cutting range is not necessarily a straight line. Figure 9 As shown in the reference point, the first intersection point c is not in the cutting range, and the method can ensure that the reference point e is in the cutting range, avoiding the cutting range processing failure caused by the positioning error of the reference point, and improving the robustness of the method.

[0100] In the above step S105, the adjacent filling color range is modified based on the cutting range according to the position of the reference point, and the updated filling color range is obtained, which specifically includes the following steps S1051-S1053:

[0101] S1051: Determine whether the reference point is in the adjacent filling color range: if yes, execute step S1052; if no, execute step S1053.

[0102] S1052: The updated filling color range is obtained by subtracting the cutting range from the adjacent filling color range.

[0103] S1053: The updated filling color range is obtained by adding the cutting range to the adjacent filling color range.

[0104] Taking the reference point shown in FIG. 7 as an example, Figure 7 and Figure 8 the reference point is not in the adjacent filling color range, so step S1053 is executed, and the updated filling color range is obtained by adding the cutting range to the adjacent filling color range, as shown in FIG. 8. Figure 7 As shown in FIG. 7, Figure 10 the reference point is in the adjacent filling color range, so step S1052 is executed, and the updated filling color range is obtained by subtracting the cutting range from the adjacent filling color range, as shown in FIG. 9. Figure 8 Figure 11 In the embodiments of the present application, in addition to being able to handle the case where the updated contour is a curve in the above examples, the method can also handle the case where the updated contour is a straight line, as shown in FIG. 10.

[0105] In the embodiments of the present application, in addition to being able to handle the case where the updated contour is a curve in the above examples, the method can also handle the case where the updated contour is a straight line, as shown in FIG. 10.​Figure 3 The right lower annular update contour line in the to-be-processed contour map is processed in detail, and a flowchart is as shown in Figure 12 As shown in the figure, the figure includes four parts, from left to right, they are a partial to-be-processed contour map, a reference point, a cutting range, and an updated filling color range.

[0106] In the embodiment of the present application, based on Figure 3 The to-be-processed contour map is as shown in the figure, and the updated contour map obtained by processing through the method is as shown in Figure 13 As shown in the figure, it can be seen that all original filling color ranges that do not conform to the updated contour line are processed, so that all updated filling color ranges conform to the adjacent updated contour line.
