Embodiment Construction

[0061] 1. Layer tracking

[0062] In the process of horizon interpretation, the interpreter’s interpretation of horizons can be simply expressed as figure 1 In the horizon model shown, the lines marked with Arabic numerals are horizon lines, the lines marked with letters indicate faults, the serial numbers on horizon lines or faults indicate their serial numbers, T3x1, P2, and P1 are horizon line names, Each layer line is composed of different line segments, and the line segment is composed of pick-up points and lines, for example: layer T3x1 is composed of 3 line segments 7, 8, and 9, and line segment 7 is composed of 5 pick-up points and 4 lines, and the line segment 8 consists of 4 pick points and 3 lines, segment 9 also consists of 4 pick points and 3 lines.

[0063] But in the actual layer line picking process, figure 1 The theoretical model shown is difficult to achieve, because of human subjective factors and visual errors, it is difficult to ensure the strict interse...

Abstract

The invention discloses a construction method of complex-structure blocky geologic model based on geologic rule constraint, comprising a horizon tracking step and a polygon cutting step. The horizon lines tracked by the horizon tracking step and the boundaries form the blocky geologic model through the polygon cutting step. The polygon cutting step comprises closing the horizon lines and the boundaries clockwise to form a plurality of polygons and processing a plurality of polygons through a cutting flow. The cutting flow for processing a plurality of polygons comprises regarding a plurality of polygons as an aggregation, taking out any two polygons in the aggregation for cutting, and putting back the cut polygons in the aggregation until all polygons in the aggregation do not intersects mutually, and finally completing the cutting flow. The method is capable of describing complex underground geologic structure, synchronously effectively performs intersection calculation on the horizon input by a user, and identifies the closed surface of the complex geologic model through a computer graphics concept.

Description

technical field [0001] The invention relates to the technical field of geological three-dimensional modeling methods, in particular to a method for constructing a complex structural block geological model based on geological laws. Background technique [0002] The purpose of constructing the velocity field in complex areas is to construct a velocity model in complex areas based on seismic data and seismic interpretation results, integrating geological, logging and drilling data in the research work of complex areas. Before the velocity model is determined, the subsurface geological model must be constructed according to the horizon interpretation results. There are two commonly used geological model construction methods: layered structure model and closed structure model (ie, block model). [0003] The characteristic of the layered structure model is that the stratigraphic interface is a continuous interface from the left boundary to the right boundary, and the interface fun...
