Abstract

The invention discloses a three-dimensional geological attribute model space-time interpolation method and system. The method comprises the following steps: generating a three-dimensional geological structure model according to topographic data, drilling data and geological profile data; partitioning the to-be-interpolated region to obtain a plurality of three-dimensional geological blocks; sequentially performing horizontal space interpolation and vertical space interpolation on the geological acquisition point attribute data corresponding to each three-dimensional geological block to obtainthree-dimensional space attribute data; constructing a complete time sequence, and performing modeling analysis and interpolation on the complete time sequence by adopting a summation autoregressive moving average model to obtain time attribute data; and fusing the three-dimensional space attribute data and the corresponding time attribute data by adopting a covariance model to obtain a three-dimensional geological attribute model. According to the method, the interpolation precision can be improved, and the integrity of space-time data after interpolation is ensured.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a three-dimensional geological attribute model spatio-temporal interpolation method and system. Background technique [0002] With the rapid economic development, the rapid urbanization process has intensified the contradiction between the supply and demand of land resources in cities. In order to solve the problems of traffic congestion and ecological environment deterioration caused by "urban diseases", it is urgent to rationally develop and utilize underground space resources. The development of underground space is inseparable from the full understanding of geological conditions and the quantitative calculation of underground space data. 3D geological modeling can intuitively understand the spatial distribution and change laws of geological entities by modeling the geometric shape of geological entities and the internal attribute parameters of geological entiti...
