Study On High Precision Fusion Processing Of Seismic Data Acquired Multiple Times

With the continuous improvement of oilfield exploration,the requirements for reacquisition of seismic data are getting higher and higher,and the difficulty is also increasing.At the same time,exploration costs must be reduced.These urgently require the use of new and old seismic data to maximize the mining of data information.High-fidelity fusion processing technology for seismic data can meet this demand.Fusion technology makes full use of the existing data collected in multiple times.By extracting more attribute information,the data is complemented in time,space and attributes,and the quality of data processing results is maximized,providing comprehensive research.The richer and more precise information,the processing of which is a technique for special processing of seismic data collected at different times,at different azimuths,and in the same exploration area,is also an extension and development of contiguous splicing processing.For data of different periods,it is necessary to unify the energy and phase characteristics of each block based on the frequency characteristics of the original data and the azimuth information,eliminate the differences caused by non-geological factors between different seismic data,and integrate data.The grid is processed to ensure that the kinematic and dynamic characteristics of the seismic data are consistent.The complementary information of the fusion processing can greatly enrich the azimuth information of the seismic data,making the seismic data a veritable wide azimuth data.This paper starts with the origin of fusion processing and current exploration needs,analyzes the development status and technical bottlenecks of the complementary processing technologies for multiple acquisitions of information,conducts a targeted analysis of the secondary 3D acquisition blocks and targets,and proposes the urgent need for systems.Sexfusion processing research and analysis applications,in order to obtain better imaging results,provide technical support for seismic exploration in key areas,save collection costs,and save energy and reduce emissions.This paper focuses on the problem of seismic data fusion in multiple 3D acquisition areas,and implements wavelet coherence technology,multi-block static time difference correction technology,signal-to-noise ratio consistency technology,prestack data fusion regularization technology,etc.In the sub-three-dimensional acquisition area,the multi-data fusion processing technology and process,and finally the actual data of the target area is tested to verify the effectiveness of the technology,and the processing results and multiple acquisition observation systems are analyzed and evaluated.Therefore,it is of great significance to carry out research on fusion processing technology to provide technical reserves and support for refinement of exploration and development.
