Abstract:Taking the construction of a three-dimensional geological model database in Shandong province as an example, taking data entry, standardization of boreholes, profile drawing, three-dimensional geological model construction, three-dimensional geological model inspection and other modeling workflows as main lines, making full use of existing geological data, the operation process of each link has been optimized and upgraded to the greatest extent, and the quality of data has been controlled to ensure the data accuracy of three-dimensional geological model, and to improve the reliability of the modeling results. It will provide important support and services for geological prospecting, ecological civilization construction, government decision-making and economic development.
