High Efficiency Method for High Density 3D Seismic Data Acquisition in Coal Field

为了提高煤田全数字高密度三维地震勘探数据采集的作业效率,分析了观测系统设计对数据采集效率的影响,针对复杂地表障碍物的不规则炮点设计,探索了制作SPS引导放炮的方法,通过读取地震数据道头,同时利用EXCEL的函数功能辅助班报填写。结果表明:变观炮点较多时SPS引导放炮能有效减少错炮,提高放炮质量和效率;提取地震数据道头信息可快速形成工作班报模板,利用VLOOKUP函数可实现工作班报自动化填写。依据上述系列工作方法的优化与综合应用,有效提高了高密度三维地震勘探的数据采集作业效率。

In order to improve the efficiency of all-digital high density three-dimensional seismic data acquisition in coalfield,the influence of geometry on data acquisition efficiency is analyzed.Aiming at the anomalous shot point design in complex surface obstacles the method of making SPS guided shooting is explored.By reading the seismic data header,the function function of EXCEL is used to assist the working shift report filling.The results show that when there are more variable shooting points,SPS-guided shooting can effectively reduce misfire and improve shooting quality and efficiency.The template of working shift report can be quickly formed by extracting the trace header information of seismic data,and the automatic filling of work shift report can be realized by using VLOOKUP function.Based on the optimization and comprehensive application of the above series of working methods,the data acquisition efficiency of high density 3D seismic exploration is effectively improved.
