| With the continuous development of oil industry technology, the oil industry constantly improve the technical requirements of all walks of life. Comprehensive logging as a necessary means of oil and gas exploration and drilling engineering decision support system in the oil and gas exploration and development plays an important role. Comprehensive logging logging software system is an important part of the instrument, which is the data processing core. In recent years, with the continuous development of computer hardware and software technology, has led the logging software systems to the systematic, platforms and network-oriented development,and resource sharing rate is higher, with a diversified, multi-tasking capabilities. But for now, at home and abroad has not comprehensive logging software been able to meet the practical application of field and simulation training.To solve this problem, this paper designed and developed a set of comprehensive logging simulation and application system. Firstly, through the analysis of the development status quo of comprehensive logging software at home and abroad and the comprehensive logging system software and hardware features, presented a overall design of the comprehensive logging simulation and application system. And the system from three aspects of research and analysis:First, the design and analysis of the system's physical structure, run the architecture, logical architecture, data architecture and database. Second, the selection of Data Acquisition Card, the design of data acquisition software.Third, the divided of module function and the analysis of the design process of the software. Through the above three aspects of the research, the paper made the following three results.First, proposed the overall design of the system,and completion of the system's physical structure, run the architecture, logical architecture, data architecture and database.Second, through the optimization of data acquisition card, based on RS-485 bus transferred designed the data acquisition system,it can use to simulate the real field data collection of comprehensive logging process,and implement hardware system of comprehensive logging teaching training;the virtual simulation data by setting the free hardware system to implement the comprehensive logging of teaching training.Through the study of the theory of the socket, designed th winsock implementation on the field for logging data acquisition software.Third,using LabVIEW, SQL Server 2000 database and other development tools, designed and developed a computer-based simulation software, the software with data acquisition, data processing, data storage and data output function.This paper designed and developed a set of comprehensive logging simulation and application system,which not only meet the needs of logging field application but also meet the comprehensive logging training needs of teaching.This system not only has the value of theoretical research but also has a broad application base and huge market potential. |
