RVSP或VSP勘探,都属于垂直地震剖面法.由于激发点或接收点置于井中,距离目的层更近,在低速层中共传播一次,具有能量衰减少,频带宽等优势,在煤层气预测、岩性勘探等领域具有广泛的适用性.鉴于RVSP和VSP在野外数据采集和波场特征方面具有很大的相似性,目前RVSP资料常规处理一般采用VSP处理流程.相对于地面地震资料处理,VSP处理软件还不够成熟,影响了RVSP技术的发展.利用地面成熟处理方法来处理RVSP资料的新思路对提高RVSP成像精度具有重要意义.实现RVSP记录与地面记录的等效转换是采用地面处理方法的关键.实际资料表明RVSP等效地面处理方法具有很好的成像效果.
RVSP or VSP exploration belong to the vertical seismic section method.As the excitation point or receiving point is placed in the well, closer to the target layer, and co-propagated once in the low-velocity layer, it has the advantages of less energy attenuation and wider frequency band. In the CBM prediction, Lithology exploration, etc. In view of the similarities between RVSP and VSP in field data acquisition and wavefield characteristics, the general processing of RVSP data is generally VSP processing.Compared with seismic data processing, VSP Processing software is not mature enough, which affects the development of RVSP technology.With the maturity of the ground to deal with RVSP data new ideas to improve RVSP imaging accuracy is of great significance.Realization of RVSP record and ground record conversion is the use of ground processing methods The key point is that the actual data show that RVSP equivalent surface treatment method has a good imaging effect.
