Abstract

The disclosure discloses a method and a processing device for stratum unconformity intersection, and belongs to the technical field of geophysical exploration data processing. The processing method includes: establishing a geological chronological deposition sequence table; determining the geological interface type of the top layer of all strata; calculating the distance field of each top layer, and determining the positive area of ​​the top layer according to the distance field of each top layer and negative area; obtain the intersection segments between all top layers; divide each top layer into multiple triangular mesh units under the constraints of intersection segments; determine the positive and negative areas of the top layer; clip all invalid areas triangular mesh unit. In the present disclosure, by determining the positive and negative regions of all top layers, the triangular grid units of the invalid regions of each top layer can be efficiently cut according to the sedimentary sequence table of geological age, and the work efficiency of complex intersection processing is greatly improved.

Description

technical field [0001] The disclosure belongs to the technical field of geophysical exploration data processing, and in particular relates to a processing method and processing device for formation unconformity intersection. Background technique [0002] In geological research work, it is often necessary to establish an effective three-dimensional structural framework model to characterize the distribution of petrophysical properties in the formation. [0003] In related technologies, unconformity and intersection often occur between strata of the three-dimensional structural frame model. In this case, the intersection line is usually obtained by pairwise intersection classic algorithm between the spatial triangular mesh surfaces, and then the layer of the stratum is divided into several independent slices based on the intersection line, and the interpolation value is re-divided, and finally according to the intersection line The main and auxiliary relations of the two stra...
