Development Of Oil And Gas Resources Sharing Platform Based On Cloud GIS

In recent years,with the improvement of China’s economic level,the oil and gas exploration and development industry has developed rapidly,and the informationization of oil and gas resources management is also steadily advancing.Based on the research of current computer and information systems,the paper decided to develop a platform based on cloud GIS for oil and gas resources sharing.This research relies on the oil and gas resource management support platform construction project of the Oil and Gas Resource Strategy Research Center of the Ministry of Natural Resources,based on cloud GIS technology,combined with spatial data index algorithm in cloud environment,analyzes platform index efficiency,and constructs an algorithm suitable for spatial data storage of oil and gas resources.Develop a cloud GIS-based oil and gas resource sharing platform.The aim is to provide users with fast,convenient,safe and intelligent services to support the research and management of oil and gas resources information management.The main work and research contents of the thesis are as follows:(1)Research cloud computing knowledge and technology architecture,including cloud architecture of Hadoop platform,distributed file system of HDFS and HBASE database;combined with cloud GIS technology,analyze the construction requirements and feasibility of cloud-based oil and gas resource management platform.(2)Research on spatial data indexing algorithm in cloud environment.By discussing the problem of unbalanced data storage load,parallel operation of algorithm threads and low efficiency of spatial query in the fast index of distributed spatial data in cloud computing environment,the advantages and disadvantages of traditional kmeans,quadtree and Hilbert curve are compared.Design a new strategy suitable for spatial data storage in the cloud environment to improve the efficiency of spatial data indexing.(3)Research and development of oil and gas resources sharing platform.Based on the research of cloud GIS technology and spatial data indexing strategy,the server develops the system based on cloud architecture,and the client visualizes and statistically analyzes the data through geographic layers and statistical charts.This study combines cloud computing technology and considers the characteristics of time and space of oil and gas resources data.It designs a fast index algorithm for spatial data in cloud environment,and develops a cloud GIS-based oil and gas resource sharing platform to realize the move of oil and gas resource management system to the cloud.The above requirements facilitate multi-users to share oil and gas resource data and bring out the greatest value of oil and gas resource data.There are still some shortcomings in this research,such as the spatial data indexing algorithm can not show high efficiency in all dimensions of the graph,the query accuracy is reduced with the quality of the sample data,and so on.
