Abstract

Embodiments of the present application provide a method and device for determining a geological model. The method includes: determining a first number of geological blocks in an initial geological model of the target area based on a closed triangular network established by geological collection points of the target area; The first number of geological blocks are grouped and merged to obtain a second number of stratigraphic blocks; the media attributes of the second number of stratigraphic blocks are set to obtain a geological model of the target area. The technical solution provided by the embodiments of this application can effectively reduce the number of operations when setting media properties, shorten the modeling cycle of the geological model, and improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of geophysical prospecting, in particular to a method and device for determining a geological model. Background technique [0002] In the field of geophysical exploration technology, the 3D geological model can effectively reflect the actual stratum conditions, and the establishment of a 3D geological model is the prerequisite for subsequent model forward modeling to better understand the stratum conditions. [0003] In the prior art, establishing a three-dimensional geological model may include forming a geological block based on a triangulation network; and then setting medium properties in units of geological blocks. However, in the prior art, the number of geological blocks formed based on the triangular network is relatively large, resulting in the subsequent need to perform multiple operations when setting the medium properties in units of geological blocks, which will bring a huge workload to the user...
