Reservoir Multi-information Integration Based On GIS

The 21st century is the information society, the development of oil and natural gas utilities need IT support. Integration of various types of information sharing, multi-disciplinary information, intelligent management decisions across time and space cooperation in the field of research and so the concept of free time and space will become the main direction of future exploration and development of oil and gas research and development decisions. Geographic information system and its rapid development in recent years has been widely used in various fields, which is petroleum geology exploration and development decision-making and create more favorable conditions for the development of information and intelligence. With the rapid development of computer technology and network technology, GIS technology has been an unprecedented rapid development, it has become more and more mature and convenient features, such as multi-source data collection, editing and input, spatial data management, each editor, a wide range of spatial analysis methods, as well as a more intuitive visualization graphic data and attribute data types of maps information data, these features are in town planning, evaluation of resources, regulatory environment, macroeconomic policy-making, forecasting disaster, various areas of social life and directing operations in solving global problems, such as has been widely used.The key issue of digital reservoir construction is the reservoirs and more comprehensive information integration and analysis. Reservoirs multi-information integration can be divided into four levels including data integration, professional integration, department integration, and enterprise integration, which includes various types of oil reservoirs database established by petro companies, as well as multi-source, multi-scale reservoir description of the research results. In the process of building a digital reservoir, how to integrate multi-source multi-scale reservoir with multiple sources of information and applies to management and dynamic analysis of reservoir development, are technical difficulties faced in the process of digital reservoir construction.The paper based on request of cooperation projects with CNPC International (Niger) Limited 《Provision of Petroleum Industry Geographical Information System S ervice for Block Agadem》 and the GIS demand of oil field, the paper uses GIS technology, focuses on the key issue for the construction of reservoirs reservoir digital multi-information integration, starts from multidimensional, multi-source, multi-scale features of multi-information reservoirs, launches a integration of multi-dimensional information, oil wells histogram automatic chart with integration on multi-scale information and research on the integration of multi-disciplinary research results and other key technologies. And on this basis, it develops a GIS-based oil reservoirs multi-information integration system. First, according to the organizational structure for the oil companies and data management model it designs Tree spatial database cluster service architecture, on the basis of the information department security assurance it achieves effective sharing of oil and gas reservoirs in the corporate sector and concurrent access to the underlying data which helps improving the service performance of spatial database. Secondly, It designs geological mapping template histogram, establishes the geologic column automatic rapid mapping method which achieves oil wells multi-scale information integration. It analysis the results of the multi-disciplinary data and maps storage format, and achieves seismic interpretation results maps, sedimentary reservoir achievement maps and other multi-source information integration; Finally, it plays space information management advantages of GIS, integrated managing the oil reservoirs multi-information of oil field exploration and development such as multi-dimensional, multi-scale and multi-source information into the reservoir multi-information spatial database; Based on oil reservoirs multi-information spatial database, using a flexible GIS method for obtaining spatial information to query and manage oil reservoirs multi-information; Using GIS vector mapping function, it can achieve basic map reservoirs automatic or semiautomatic vector mapping, thus to improve the efficiency of reservoirs cartographic maps and accelerated the process of digital reservoir construction.Thesis research work carries out for future achievement on multi-information integration management into spatial database of oil field exploration and development, which is in favor of sharing Oil enterprises internal information and multi-disciplinary research Key technology research for multi-information integration of reservoir will enrich the basic theory of digital reservoir construction. Reservoir multi-information integration based on established research papers has some practical reference value in the digital reservoir construction.
