Abstract

The invention belongs to the technical field of stratum stratification, and provides a stratum stratification method based on anisotropic interpolation: exploring boreholes, recording stratum lithology names and stratum lithology depth ranges, establishing a cubic network according to the drilled holes during the exploration, and dispersing boreholes into multiple data points along the depth direction; selecting a stratum lithology name, and performing differentiated assignment on discrete data points in the boreholes according to whether the discrete data points in the boreholes fall within the stratum lithology depth range to serve as sample points; further performing anisotropic interpolation in the cubic network according to a specified trend in accordance with attribute values of the sample points to generate an attribute isosurface; and sequentially generating the attribute isosurfaces corresponding to the stratum lithology names according to the above operations, and dividing stratum stratification according to the lithological isosurfaces. In view of the situation that the artificial stratification is difficult or impossible due to more lithological duplication of site lithology and interbedding development and the like in an actual survey process, the stratification results of complex geological conditions can be obtained quickly and accurately by adopting the method.

Description

technical field [0001] The invention belongs to the technical field of stratum stratification, and in particular relates to a stratum stratification method based on anisotropic interpolation. Background technique [0002] Due to the variety and complexity of the soil layer, the typical characteristics of layer repetition and lens development are ubiquitous. In the actual survey work, when encountering such geological conditions, it brings great difficulties to artificial stratification. The traditional single hole Layered and two-dimensional proofreading methods cannot guarantee the spatial rationality and correctness of the layered results. For strata with relatively clear geological age and good depositional rules, stratification can be completed by means of manual single-hole operation. When the structure is affected or the geological conditions are complex, manual stratification is also difficult, and even stratification cannot be achieved. Condition. For example, the ...
