The Research And Design Of Seismic Data Processing Platform Integrated Framework

In recent years, along with the ever-changing development of science and technology, the pace of digital oilfield construction becomes more and more quickly. In the field of petroleum and gas exploration, the development of seismic technique and computer technology is complementary to each other. With the innovation of oil exploration technology, the data quantity is bigger and bigger. It causes the existing integration platform softwares faced a lot of problems in many aspects such as adding advanced technology processing module and managing the chunk of seismic data.The paper designs a prototype of framework for the seismic data integration platform, by analyzing the development trend of the seismic data integration platform in the world, and the problems in processing seismic data.Different with the similar products, the framework of integrated platform researches the advanced technology module integration, workflow management, data transmission between modules and the application of the chunk data in the system.The main contents of this paper are as follows:1.By analysising the architecture and development trend of the current seismic data processing software in the global scope,and combining the problems of the current seismic data processing, the paper abstracts the model of integration platform framework. The model lays the foundation for designing the seismic data processing and integration platform.2. According to processing the seismic data, the corresponding workflow management program is formulated, which researches the management of chunk data and data transmission between module resources, improves the Data flowing efficiency between the integration frameworks, ensures data consistency and integrity.3. By the researching of the characteristics of seismic data, gather data uses the read mode on the base of memory mapping. The way to read data through the establishment of disk space and the mapping of logical address space improves the efficiency of data access. It is faster than the system function of the read and write.
