煤矿采区三维地震资料连片处理关键技术及其应用
Key technique of 3D seismic data merged processing and its application in the coal mining district
摘要
Abstract
This paper analyzes the main technical difficulties in the merged processing of 3D seismic da-ta in different coal mining areas due to the inconsistency of acquisition parameters and construction con-ditions.It proposes a solution for the merged processing of 3D seismic data and constructs 3D seismic data merged processing flow.Under the unified layout system conditions,the paper adopts a combina-tion of static correction and residual static correction to calculate the static correction amount of different area data and complete the static correction processing of the whole area.The pre-stack combination denoising method adopts classification,step-by-step,frequency division,domain division,and time-di-vision processing to selectively suppress noise and improve the signal-to-noise ratio of seismic data.The surface consistency amplitude compensation method is used to eliminate the spatial differences in seis-mic wave energy caused by changes in shot and receiver points,and achieve amplitude balance of sur-face consistency throughout the whole area.After establishing a reasonable migration velocity body,pre-stack time migration is carried out to obtain a migration data body with obvious wave group charac-teristics and reasonable positioning of reflection waves and fault plane waves.The actual seismic data processing results show that the established 3D seismic data merged processing technology and flow can effectively eliminate the inconsistency of seismic data in different areas and improve the processing quality of seismic data at the boundaries of different areas.关键词
