| Our country had already moved the exploration targets into the western of China in recent years,where is covered by hill,desert and loess tableland.Carbonate reservoirs have become an important target for global oil and gas exploration and many exploration results about carbonate reservoirs has be made by the professionals.A series of seismic data process technologies for carbonate reservoirs of JingBian gas field were presented this paper based on the experience of previous people and the author's research results.First of all,the geological modeling of the carbonate reservoirs in the study area is carried out based on the geological data and the numerical simulation is accomplished.It is concluded that the seismic wave energy is strongly absorbed by the carbonate reservoir modeling,and diffraction arises in the modeling of fractural-cave reservoir.All the results show that amplitude compensation and migration are significant to the process.Secondly,the author started the study from the analysis of seismic data in this article,taking a series of technologies like tomography static correction,K-L transformation,deconvolution,and amplitude compensation technology as the key-technologies according to the results of the analysis.And the seismic data quality was improved obviously through the application of these technologies.At last,the author used migration to suppress the diffraction in the seismic data and got a good result.Except the above key-technologies,the author also applied some auxiliary technologies into the data process and got a stack section with feature of carbonate reservoir.In addition,what can the author summarized in the denoising process was that the noise can be suppressed gradually for different energy from strong to weak.The noise suppression and the effectivewave amplitude recovery can be used interchangeably,and this way is effective when being applied in the data process of this paper. |
