摘要
对于火山岩相的识别,首先应用测井资料对单井进行火山岩相的划分,然后通过标定地震剖面,对不同火山岩相地震反射特征进行归纳总结,在地震剖面上进行地震相的解释和追踪,最后进行井震结合,并建立火山岩相与地震相之间的关系,完成地震相向火山岩相的转化,从而得到火山岩相的平面分布预测。
Volcanic facies identification is based on single well volcanic facies identification by using the well data,then calibrating the seismic cross section to the well.In this paper,we sum up the seismic reflection characteristics of different volcanic facies,and process the seismic facies interpretation and trace the distribution of the facies in seismic cross section.Finally,by establishing the relationship of the volcanic facies to seismic facies,we complete the inversion from the seismic facies to the volcanic facies.Then,the distribution of volcanic facies in plane is predicted.
