Design And Development Of The Geological Statistical Analysis System

At present, exploration in Shengli O ilfield becomes maturing day by day, the exploration goal is becoming complex. The geologist is requiring much clearer geologic characterization and becom ing rely on advanced geology analysis. From the comprehensive point of view, this articl e has thoroughly analyzed the subsurface geologic body research situation and the function of geologic statistical of domestic and foreign geological software. Combined with business dem and from practical work and usability, the geology statistical analysis system was developed.The whole system is based on.NET Fram ework platform environment, and C # was used for program development, database systems using ORACLE, and data news release by means of Web Serv ices data services. Through research of geostatistical analysis methods, methods such as m ean method, reciprocal method, linear regression method, kriging and other statistical analysis m ethods were used. In this thesis, flexible and controllable data statis tical techniques was res earched, and the rule base was designed for business metrics and business elem ents. The user can enquiry self-defined rules by self-defined rules base, and the rule base can be extended to compare index and statistical analysis of the business points. This thesis have also studied drawing techniques based on geostatistics contour, customizable comparison chart display and other technologies; additionally, EXCEL te mplates, XML templates were also used in layering standardization, the initial interface customization.Through information technology, by m eans of massive basic inform ation in exploration database, according to geostati stical theory, mainly from the horizon, lithology, physical properties, hydrocarbon-bearing potential, formation pressure and temperature, velocity, reserve area, a la rge number of geologi cal raw data wer e statistical analyzed. Concerned about the area, wells and horizons, geologic attributes, such as, lithology, physical properties, hydr ocarbon-bearing potential, pressure and temperature, velocity, reserves could be got. The data on the st atistical results fro m enquiry can be packaged download, and can be compared and analyzed by histogram s, line charts, scatter plots and contour m aps to achieve cross-disciplinary comparative analysis. The system also en ables flexible, efficient, m ulti-source heterogeneous database data statistical analysis and co mparative analysis of custo mizable maps, contour mapping.This system is a prelim inary pilot for massive data m ining technique in information statistical analysis tech nology, and filled th e blank in s tatistical analysis about the exploration information to support exploration work. Up to now, this system has been used in Shengli Oilfield exploration widely.
