Research On Visualization Technology Of E&P Data Model In Oilfield

Exploration and development data standardization has become an important task of information development in the domestic exploration and development field,in recent years it has gradually attracted much attention.E&P data model is an organized collection of abstract data,for first time users,it is a difficulty problem to read and understand E&P data model.In order to help new users learn quickly understanding the E&P data model,introduce the visualization technology,and propose a visualization scheme of E&P data model,based on the POSC Epicentre data model.Firstly,this topic expounds the research status quo about POSC data model standard and the visualization technology,and then introduces visualization technology in details,including the generation and development,characteristics,classification and so on.Based on visualization technology,extend and implement visualization data model in the oil exploration and development field,this paper mainly studies the following problem:1.Based on the define method and hierarchical organization structure of POSC E&P data model,analyze the classification rule of the data entities in E&P data model,and put forward visual extension scheme,which is suitable for E&P data model.2.Study the characteristics and methods of visualization technology.Taking the multimedia data visualization method,analyze the characteristics and the storage methods of multimedia data,and provide a theoretical basis for visual implementation of E&P data model.3.Analyze the characteristics of the data entities in E&P data model from the view of the business model.According to the visual description feature,provide the reference for further research of the visual E&P data model,which is based on the visual classification rules of business model.4.According to the extension scheme of E&P data model,realize the revision of the E&P data model,and provide the related algorithm to realize visualization of E&P data model.5.Using the object-oriented technology,built a multimedia model database,which is matched to E&P data model,and then give the hierarchical architecture of the multimedia model database,the mapping rules between data model and the storage method of multimedia data.Through research,use the visualization analysis and research of exploration arid development data model based Epicentre,to achieve the data model of exploration and development visualization expansion and data entity visualization by type,laid the foundation to the data model of exploration and development visualization,use the multimedia models libraries,further achieve the data model of exploration and development visual display,provide a guarantee for its data visualization.
