Integration Techniques Of E&P Data Management Based On GIS

The data of oil exploration and development is characterized by distribution,multi-source and mass,the data isolated islands in large enterprises are obvious,and the problems of data integration are urgently needed to be solved.The purpose of this paper is to study the data integration of exploration and development to eliminate data isolated islands and realize the data connectivity.Features,analyzes the exploration and development data of master data to the exploration and development support for data integration model,heterogeneous data virtualization new mode and a data fusion for upper logic unified integrated quality control prodedure and integrated visualization scheme.First of all,the conclusion summarizes and analyse the characteristics of every kind of business,involving the data content and characteristics,figure out the present situation of E&P data integration,requirements,problems and challenges.On the basis of data analysis,this paper puts forward the exploration and development of heterogeneous data integration model based on master data,analyze the domestic and international prevalent E&P data model standard,point out the data integration rule,summed up the E&P master data structure,analyzes the logical relationship between the master data,design the relationship between the master data structure tree and master data management model and the whole life cycle of exploration and development main data management model.Designed the E&P data integration virtualization architecture,virtualization of exploration and development of heterogeneous data fusion technology for research,design has realized the distributed data access and scheduling strategy and event-driven data monitoring and synchronization method,solves the exploration and development data management of sharing a large number of heterogeneous data integration problem.Proposed and constructed the E&P data integration quality control procedure,in-depth analysis of the E&P data sources of quality problems,give the principles and standards of data quality control,to form the three different kinds of data quality control methods,build a more complete data quality control methods of the system.Taking seismic data as an example,the accuracy and application range of different data storage types are demonstrated,and some suggestions are provided for data quality control in practical applications.Comprehensive utilization of interdisciplinary knowledge and methods to study the integrated E&P data visualization of core technology,put forward the geological modeling method based on the geophysical exploration results,on the basis of the establishment of underground structure static model,dynamic information,combined with production key technology of 3D modeling and 3D visualization were studied,especially in modeling,3D geological model based on parallel section of the dynamic update to do a thorough theoretical analysis and practice,we have created a unique interdisciplinary integration and comprehensive E&P data integrated visualization scheme.In the end,the paper summarizes and prospected the future application of E&P data integration in oil industry.
