Abstract

The invention belongs to the technical field of stratum stratification, and provides a stratum stratification method based on anisotropic interpolation: Exploration drilling records the stratum lithology name and the depth range of each stratum lithology, constructs a cubic network according to the exploration drilling, and divides the drilling Discretize into multiple data points along the depth direction. A formation lithology name is selected, and according to whether the discrete data points in each borehole fall within the depth range of the formation lithology, the discrete data points in each borehole are differentially assigned as sample points. According to the attribute values ​​of the sample points, the anisotropic interpolation is further performed in the cubic network according to the specified trend, and the attribute isosurface is generated. According to the above operations, the attribute isosurface corresponding to each lithology name is generated in turn, and the stratum is divided according to each lithology isosurface. This method is aimed at the situation that artificial stratification is difficult or impossible in the actual survey process when there are many repetitions of site lithology and the development of interbeds. The stratification results of complex geological conditions can be obtained quickly and accurately.

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 ...
