摘要
非零偏移距VSP就是在距离井口有一定距离的位置放炮 ,在井内安置检波器接收地震波 ,属于二维观测。通过资料处理 ,可以得到井口附近的一段高分辨率的P波地震剖面、PS波地震剖面 ,也可以提取地层属性参数。联合应用P波剖面、PS波剖面和地层属性参数可以直接检测油气层和油气层的的横向分布范围。
The shot is located in some distance from well and the geophone is positioned inside the well to receive the seismic wave, the method is called VSP which belongs to 2D data acquisition. By data processing, P-wave seismic section, PS-wave seismic section can be attained and also the layer attribute can be extracted. Not only the oil and gas layer, but also the lateral distribution of it can be detected by synthetically analyzing P-wave section, PS-wave section and the layer distribution.
