METHOD AND DEVICE FOR DETERMINING DAMAGE TO A GEOLOGICAL MODEL

摘要

The present invention relates to the determination of damage to a geological model (100) comprising a plurality of nodes (200) and a plurality of links (300) each linking two nodes from the plurality of nodes.;For each link from the plurality of links, the determination of damage comprises determining a force applied to said link. If the force is greater than a force threshold value, for each node of the two nodes from the plurality of nodes linked together by said link, the determination of damage comprises creating a contact sphere (400) associated with said node, and eliminating the link.;Finally, the determination of damage comprises determining a plurality of contacts between spheres comprising at least one contact between spheres, each contact between spheres associating two contact spheres from the plurality of contact spheres.

1. A method for determining damage to a geological model, said method being implemented by computer means, said geological model comprising a plurality of nodes and a plurality of links, each link from the plurality of links linking together two nodes from the plurality of nodes, the method comprising the following steps,
for each link i from the plurality of links:
determining a force applied fappi to said link,if said force is greater than a force threshold value fci: for each node j of the two nodes from the plurality of nodes linked together by said link i, creating a contact sphere associated with said node j, eliminating said link i, determining a plurality of contacts between spheres comprising at least one contact between spheres, each contact between spheres from the plurality of contacts between spheres associating two contact spheres from the plurality of contact spheres.
