摘　　要：地震速度测井称为VSP测井,它是目前地震勘探求取平均速度和求取底层速度的直接手段。利用求取的速度资料,除可提供较准确的地层沉积厚度,预告新井层位及构组地震剖面外,对进行地层地震学,人工合成记录,都给出了很重要的依据。目前,多次覆盖地震勘探方法已广泛采用,声波测井也在地震解释中普遍采用,虽然能给出一些速度参数,然而,由于地震测井速度是取自直接的,受影响变异小,所以,到目前为止,只有用地震速度测井所求的平均速度才可代表该地区真实的平均速度。因而,只有它对验证各个换算的"平均速度"起着极重要的作用。文章对地震测井求取速度方法进行分析论证,确保求取的速度可信,为地震资料处理和地震资料解释提供准确的速度,提高地震勘探的精度,增加经济效益。The seismic velocity logging calls as VSP logging, it is a direct means of seismic exploration to strike the average speed and strike the bottom of speed. To use to strike the data of speed, in addition to provide more accurate sedimentary thickness, notice of the new well-layers and structure group of seismic profiles, stratigraphic seismology, synthetic records are given a very important basis. Multiple coverage seismic exploration method has been widely used, commonly used in the sonic log is also seismic interpretation, although we can give some speed parameters, however, seismic logging speed is obtained from the direct affected small variation, so as far, only average speed of seismic velocity logging requests on behalf of the real average speed in the region. Thus, it only verifies the average speed of each conversion plays a very important role. This is the seismic logging strike speed of analysis and appraisal to ensure speed to strike a credible, to explain the seismic data processing and seismic data to provide accurate speed, to improve the accuracy of the seismic exploration, and increase economic benefits.
