Problems solved by technology

[0003] Gridding technology is the key to the automatic drawing of contour maps. Seismic data often contain faults, making the geoscience surface very complex. Because the original data are often unevenly distributed, sometimes clusters of extreme cases appear, which is It will cause the weight of some directions to be too large and the weight of other directions to be too small during gridding, resulting in inaccurate valuation and affecting the rationality of gridding, so that the effect of automatic tracking and drawing is not good, and the existing technology cannot be realized Meshing Data Containing Fault Combination Lines

Embodiment Construction

[0028] The embodiment of the present invention adopts the following steps:

[0029] The first step is to preprocess the discrete point data. Determine a slightly larger range according to the range of the grid, build an index grid based on this range, and index discrete data into the grid.

[0030] Preprocess the discrete point data, that is, create an interpolation grid on the area specified by the user, and build an index grid on an area slightly larger than the interpolation grid. The density of the index grid is that each grid unit contains no more than 4 to 6 data points prevail. The discrete data is projected onto the specific unit of the index grid and the index number of the scattered point is recorded. According to the index grid unit where the interpolation grid node is located, the discrete point in the index grid unit is searched unit by unit from the inside to the outside. This eliminates the need to find data points in the entire array of discrete points, great...

Abstract

A latticing method for plotting rectangular net of isograms containing normal fault geological body structure includes carrying out pretreatment on scatter data and setting up index for it, carrying out pretreatment on fault layer data and setting up index for it, carrying out data search and interpolation for each lattice point to enable not to seek data point in all discrete point array for raising search speed of data greatly.

Description

technical field [0001] The invention relates to geophysical prospecting and mapping technology, in particular to a rectangular grid meshing method for automatically tracking and drawing contour maps of geological body structures containing normal faults. technical background [0002] During petroleum geological exploration, it is necessary to draw the collected and processed seismic data into a geological structure map. For data with complex fault combination lines (polygons), gridding is required before automatic tracking and drawing of contour lines . Gridding is to use the surrounding discrete data points to calculate the value of the grid node by using the method of fitting or interpolation for the nodes on the regular rectangular grid. [0003] Gridding technology is the key to the automatic drawing of contour maps. Seismic data often contain faults, making the geoscience surface very complex. Because the original data are often unevenly distributed, sometimes clusters...
