A method for determining the web of a beam through a three-dimensional geological medium.

摘要

The invention relates to a method of determining the trajectory of a ray from a first point or point source to a second point or point receiver, through a three-dimensional geological structure of which the interfaces between the layers were modeled in the form of a meshed surfaces comprising a plurality of points, whose geometrical coordinates are known and are joined in pairs by segments of straight line defining the triangular facets contiguous. & br / according to the invention, this method comprises the following phases: & br / - to be determined in the vicinity of an initial reason whatsoever, among the paths starting from the first point and passing through at least a crown of a triangle of each of the surfaces 1 in order to arrive at the second point, the optimal path corresponding to a minimum journey; & br / - b disturb the optimal path thus determined by taking into account the characteristics of the tips of the neighboring triangles of those taken by this optimal path.
