AVO技术出现于1984年。它是在叠前道集上分析振幅随炮检距变化的规律,以估求岩石的弹性参数,分辨岩性及孔隙填充物,直接寻找有用矿藏(如气藏、油藏等)的一种方法。该方法问世以来,得到广泛应用井获得很多成功的实践,为油田开发提供了可靠井位但振幅与炮检距的关系是由多种因素决定的,AVO解释中陷井的出现,除噪音因素外,还有波的传播效应的影响等,这就需要对采集到的资料进行各种校正和补偿,减少影响AVO效应的非地质因素,突出其油气效应,使之在油田勘探与开发中发挥更大的作用。
AVO technology appeared in 1984. It is the prestack gather to analyze the variation of the amplitude with the offset from the law to estimate the elastic parameters of rock, lithology and pore filling to distinguish, directly looking for a useful mineral resources (such as gas reservoirs, reservoirs, etc.) a method. Since the advent of this method, many successful practices have been obtained and used widely for oilfield development. However, the relationship between amplitude and offset is determined by many factors. The emergence of traps in AVO interpretation, in addition to noise factors In addition, there is also the influence of the wave propagation effect, which requires various corrections and compensations for the collected data to reduce the non-geological factors that affect the AVO effect, highlighting their oil and gas effects and making them play an important role in the exploration and development of oil fields Greater effect.
