Embodiment 1

[0039] Such as figure 1 As shown, a 3D geological model data conversion method based on Geo3DML is mainly based on the Geo3DML data exchange format to convert the 3D structural model data (GOCAD ASCⅡ) established by SKUA-GOCAD into data that can be used by third-party platforms (such as MapGIS, SuperMap) The 3D model data (.xml) used, because the components of Model3d and Geo3DML include geometric information, visualization information and attribute information, and there is a one-to-one correspondence between the two in the geometric data structure, therefore, both Whether there are conversion bases and conditions on the model geometric structure or topological relationship, specifically, the steps of the specific conversion method in this embodiment are as follows:

[0040] Step 1. Identify and read the key data in the Model3d file;

[0041] Step 2. Establish a corresponding temporary storage structure;

[0042] Step 3. Temporarily store the read key data in a temporary st...

Abstract

The invention discloses a three-dimensional geologic model data conversion method based on Geo3DML. The three-dimensional geologic model data conversion method comprises the following steps: A, identifying and reading key data in a Model3d file; B, establishing a corresponding temporary storage structure; C, temporarily storing the read key data in a temporary storage structure; D, establishing aGeo3DML data structure corresponding to the Model3d file; and E, transferring the temporarily stored data into the Geo3DML framework. According to the method, based on a Geo3DML data exchange format,three-dimensional structure model data (GOCAD ASCII) established by SKUA-GOCAD is converted into three-dimensional model data (.xml) which can be used by a third-party platform (such as MapGIS, SuperMap), and the application range of the SKUA-GOCAD modeling result can be further expanded.

Description

technical field [0001] The invention relates to the technical field of geological data conversion, in particular to a Geo3DML-based three-dimensional geological model data conversion method. Background technique [0002] Currently, there are many standards for exchanging geological data formats. For example, GeoSciML for traditional two-dimensional geological object data exchange, and RESQML for three-dimensional reservoir object data exchange in the oil and gas exploration industry (see Wang Z, QuH, Wu Z, et al. 2017. Geo3DML: A standard-based exchange format for 3D geological models [J]. Computers & Geosciences, S0098300417302716). However, these criteria still more or less lack expression of the geological model itself as a whole. Geo3DML appropriately expands on the basis of existing conversion standards, defines a new organizational framework and storage format for 3D geological model data exchange, and further improves the storage, exchange and sharing methods of 3D ...
