多波层位对比的原则与方法

PRINCIPLES AND METHODS IN SEISMIC LAYER CORRELATION USING MULTIWAVE REFLECTIVE DATA

正确识别同一地质层位的纵横波是多波多分量资料联合解释的首要任务，也是多波勘探与Ｐ波勘探相比可减少地震反演多解性及提高储层、岩性、油气预测成功率的重要步骤。本文在地震、测井、地质、计算机技术等多学科交叉与综合的基础上，提出了多波层位对比原则与对比标志，并总结出一套实用的对比方法及技术流程。经实践表明，该理论与技术是正确可行的。

It is very important to identify whether the seismic events in different component records of p and s waves come from the same reflective layersin seismic integrative interpretation. Using seismic multiwave exploration can decrease the possibility of multisolution in seismic inversion and increase the efficiency for identification of reservoir properties and lithological parameters and oil exploration. In this paper we provide a number of principles and marks in layer correlation of multiwave data based on the integration of multidisciplines such as seismic, well log, geology and computer technology et al. According to those principles and marks we also present a set of layer correlation methods and their corresponding technological flow charts which efficiency are tesed on real and synthetic seismic multiwave data.
