VSP(Vertical Seismic Profiling)——垂直地震剖面法勘探技术,是80年代发展起来的一种新的地球物理勘探方法。它是在地表设置震源激发地震波,在井中设置检波器接收,即在垂直方向观测人工波场。它的发展首先受到计算机技术的制约,从刚开始的零偏VSP及只能提供出时-深关系和地层速度到目前的非零偏VSP及利用VSP资料提取出真子波、用VSP初至波和上行波关系预测未钻遇地层、用VSP资料中波的传播关系识别地面地震记录上的多次波、利用三分量中的一些特征参数与声波测井和电法测井的资料相结合来研究地下构造及岩性等,都是计算机技术的发展在VSP应用中的体现。
VSP (Vertical Seismic Profiling) - vertical seismic profiling technology, is a new geophysical exploration method developed in the 1980s. It is set up on the surface excitation seismic waves, the receiver set in the well, that is, in the vertical direction of the artificial wave field. Its development was first constrained by computer technology. From the very beginning of the zero-offset VSP and only to provide a time-depth relationship and the formation velocity to the current non-zero partial VSP and the use of VSP data to extract the real wave, with the VSP first arrival wave And upwelling waves are used to predict the undisturbed strata. The multiples of the ground seismogram are identified by the propagation relationship of the midwave of the VSP data. By using some characteristic parameters of the three components in combination with the data of acoustic logging and electrical logging Research on underground structure and lithology are all examples of the development of computer technology in the application of VSP.
