Design And Implementation Of Seismic Data Processing System In Liaohe Area

Liaohe oil field seismic area of large span, shallow layer seismic geologic conditions and deep geological characteristics determines the Liaohe Oilfield blocks most of the original seismic data signal-to-noise is relatively low. In recent years, in order to improve the quality of seismic data to meet in Liaohe Oilfield in the requirements of the small fault block, micro amplitude complex structural and lithologic oil and gas reservoirs exploration, exploration and Development Research Institute of Liaohe oil field seismic data processing center in improve its processing characteristics of technology at the same time, is also an urgent need to develop its own characteristics of the seismic data processing system.The main research work in this paper is as follows:1.From the view of object-oriented design, according to the specific requirements of exploration in Liaohe area, the relevant provisions of the seismic design of seismic project overview, system requirements analysis, design principles and system architecture and design and the function design, the realization of the Liaohe oil field seismic data processing system.2.according to the characteristics of seismic data in Liaohe area, this paper analyzes the requirement and design principle of data processing system, and designs the user interface, the file management module and the characteristic processing module of the system. The functions of the specific design include static correction, amplitude compensation, pre stack noise removal, the signal to noise ratio and resolution of seismic data, and so on.3. Through system test, The system shows good performance, especially in static correction, amplitude compensation and prestack noise removal process reflects the software originality, especially to improve the signal-to-noise ratio of seismic data, the resolution has its special advanced function module.Liaohe area seismic data processing system has the following advantages: post-processing signal-to-noise ratio was improved obviously; stack profile clear faults, breakpoints; clear wave group characteristics, higher resolution.4.In the practical application, the system fully embodies the advantages of technology and platform, and the robustness, accuracy, adaptability of the system and the simplicity of operation. But, the system processing module as part of the advantage in the test could not fully demonstrated, also found that the denoising module still exist many defects, also needs to be improved and perfected.
