摘要
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 and VSP exploration belong to vertical seismic profile method.The shot point and receiver are located in the well,so the distance from the target layer is closer.Meanwhile the seismic wave propagates in low velocity only once,it has advantage of less energy attenuation and wide frequency band,therefore RVSP and VSP method have wide application in coalbed methane prediction and lithology exploration area.Because of the similarities in data acquisition and wave field character between RVSP and VSP,the general RVSP data processing adopts VSP processing workflow.Due to the immaturity of RVSP processing software relative to surface data processing,it influences the RVSP development.Using mature surface processing method in RVSP data processing has important significance in improving RVSP image accuracy.Realizing the RVSP record and surface record equivalent transformation is the key of using surface data processing method.Actual information demonstrates that RVSP equivalent surface data processing method has a good imaging effect.
