Embodiment Construction

[0013] The present invention will be further described below with reference to specific examples.

[0014] A method for automatically analyzing geological bodies based on a three-dimensional stratigraphic model in an embodiment of the present invention includes the following steps: S1: Set the threshold of geological body attribute values ​​on the attribute profile, determine the layer that needs to be extracted, and Geobody auto under Advanced Interpretation Create an analysis viewer in the middle, select the 3D stratigraphic model as volume 2 as the bottom data, and then select the seismic attribute volume that can reflect the geological body, and adjust the color to reflect the attribute threshold of the geological body; S2: automatic segmentation of the geological body contour line Extract, automatically generate a large number of horizon stacks in the selected layer, and pick the contour line of the threshold of the geological body attribute on each slice based on the basi...

Abstract

The present invention relates to a geologic body automatic analysis method based on a three-dimensional stratum model. The method comprises the steps: S1: arranging a geologic body attribute value threshold on an attribute profile; S2: automatically extracting a geologic body slice contour; S3: making the triangular mesh of the contour line to generate a geologic body envelope surface; and S4: calculating the area and the size of a geologic body object. The geologic body automatic analysis method based on a three-dimensional stratum model provided by the invention generates the triangle meshing through automatic serial section enveloping scanning to obtain geologic body object data and description parameters such as the area, the volume and the like.

Description

technical field [0001] The invention relates to an automatic analysis method of a geological body based on a three-dimensional formation model. Background technique [0002] The 3D hollowing out display technology of the current large-scale seismic interpretation software only hides some worthwhile colors through the setting of the threshold value, so as to obtain the 3D display of the target geological body, but it is only displayed, and the geological body cannot be obtained. Actual object data. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, the main purpose of the present invention is to solve the defects of the prior art. The present invention provides an automatic analysis method for geological bodies based on a three-dimensional stratigraphic model. The analysis method uses automatic continuous slice envelope scanning , generate triangular grids for 3D geological bodies, and obtain geological body object data and descrip...
