逐点激发井深设计网格化方法的选取
|
摘要
随着地震勘探的不断深入,地震资料采集要求主频足够高,频带足够宽,能量足够强,而逐点激发井深设计有助于获得满意的地震信号,要设计合理的井深,网格化方法的选取非常重要。这里首先介绍了Surfer软件中十二种网格化方法原理特征,以及在逐点井深设计上的应用;然后运用Surfer软件中不同的插值方法,对BIN12工区岩性数据进行网格的效果对比与网格的密度探讨,选取了最佳的网格化方法;最后针对几种网格化方法进行井深对比试验,通过资料分析,说明了设计的井深合理,选取网格化方法的效果较好。
With the in-depth development of seismic ex- ploration,the requirement for seismic data acquisition is high enough frequency,wide enough band and strong enough energy of the seismic signals. The technique for design of point-by-point dynamic shot-hole depth can help obtain satisfying seismic signals.The choice of gridding methods is very important with the satisfing shot depth.In this paper,firstly,it referred the 12 principles of grid characteristics about Surfer and it s the application for point-by-point dynamic shot-hole depth design.Then the different interpolation methods in Surfer are used to process the BIN12 area lithology data and compared the effect to select the best method of gridding.Finally,the good results is achieved in the comparative tests of several methods of gridding for different shot hole depth,which shows that depth of the design is reasonable,and selected the gridding method is better.
