Research On Integrated Approach Of Oil-gas Exploration Multidisciplinary Research Achievement Drawings Based On Spatial Information Technology

In the process of oil and gas exploration and development,the integration of multidisciplinary production maps has always been a difficult issue.Most of these production maps come from different software with different formats in different storage departments.There is no unified and efficient management for them.The emergence of Geographic Information System(GIS)makes the production maps management of oil and gas exploration toward the direction of integration and visualization.At present,the integration of production maps by major oilfield companies is mostly a co-existence management model for electronic and paper maps.This management model is likely to cause confusion in map management and is not convenient for comprehensive analysis of production maps.The application of GIS spatial information technology can be a useful solution to the spatial correlation between multi-scale,multidimensional production maps of the oil and gas exploration process.The integrated management of multidisciplinary production maps of oil and gas exploration is realized with the help of a geospatial database.In this paper,the application of GIS in the integration of oil and gas exploration multidisciplinary production maps is studied.With the help of the GIS spatial information organization model and the secondary development of ArcGIS Engine,the various geological maps involved in oil and gas exploration are organized and stored together in a large spatial database to facilitate the integration of information management,so as to achieve information sharing.Meanwhile,the symbolic information of the production maps is transformed into data information,which is convenient for the geological researchers to carry out the superposition and comprehensive analysis.The main contents are as follows:(1)integrated management of multidisciplinary production maps: according to the GIS geospatial database,the construction of multidisciplinary spatial database for oil and gas reservoirs is completed,and massive production maps of geological exploration are integrated and managed in a spatial database.(2)data modeling: production maps expressed by color rendering and other methods are converted to a raster data model stored directly in the data.The data modeling method based on the raster model is studied from discrete data modeling and continuous data modeling.(3)the integrated multidisciplinary analysis platform of production maps for oil and gas exploration is developed.Based on the actual need,the comprehensive integrated analysis platform for oil and gas exploration multidisciplinary production maps is designed from the three aspects of multidisciplinary production map integration,image data modeling and auxiliary function.Taking the data of a block in Sulige gas field as an example,this paper uses the system to integrate the management of the production maps of the research block,and establish a data model.Test results basically achieve the desired results.
