Study On Seismic Processing Technology Of Amplitude Balance About Fu Yu Oil Layer Density Reservoir In Song Nan

The study area in the essay belongs to fluvial deposit, channel develops very much, but the channel sand body change quickly in the longitude and transverse, reservoir’s heterogeneity is strong and reservoir is dense, which is hard to identify single sand body. It’s the biggest problems about restricting reservoir exploration and development. Therefore, the research content of this area is of great significance to the reservoir prediction work.In order to solve the problem of the reservoir prediction, I started form the original data, carried out seismic data processing and solved the problems about amplitude balance, aiming at seismic data under the complicated geological conditions. The paper mainly adopts the technology of improving signal-to-noise ratio and the resolution, energy compensation technology, static correction technology, the data regularization technique, migration imaging and so on. The application of these technologies has reached the expected effect, supporting the exploration work From the final processing results, the technology of the spatial amplitude correction and the data regularization technology improves the data quality, which makes the energy of the pre-stack gathers more balanced, eliminating the imbalance phenomenon of CRP gathers and the energy, improving the imaging accuracy; from the perspective of the amplitude attribute,it eliminates the work area boundary effect and enhances the amplitude of the AVO response;But from the perspective of the extension frequency before and after the extraction of amplitude attribute,the processing of the extension frequency has a great influence on amplitude balance. Therefore, middle shallow layer should be given priority to deal with amplitude balance and extension frequency processing is complementary.The study in the essay is of great significance to the reservoir prediction work in Song Nan,Jin Lin Oil field,solving the problems of restricting the reservoir prediction in seismic data.The 80% accuracy of the reservoir prediction depends on seismic data. Some processing methods have played a key role in improving the quality of the seismic data,and the data has reliable practicability.Therefore, the important processing methods in the essay have good value of popularization and application.
