| 摘 要： | 本文利用从地震数据中提取的主振幅参数，通过与钻井岩性参数相关拟合分析，排除地震调谐影响，确定地震数据中所包含的岩性信息，结合钻井沉积图，测井相研究成果和区域沉积特征，把地震主参数有效地转化为沉积相，实现了从角度研究古沉积环境，并在此基础上确定有利的储层分布区，经后期钻探获得高产油气流证实，该方法的沉积相发结果是准确的，从而为地震资料的地质应用了一个新的方法，为沉积微相的研究提供了一种新的手段。

| Abstract: | Main amplitude parameters extracted from seismic data are used to get lithology information by correlating with drilling lithology parameters and removing seismic modulation effect. Combined with drilling sedimentary facies,logging facies and regional sedimentary characters, the seismic main amplitude parameters are effectively transformed into sedimentary microfacies. Accordingly, the favourable reservior distribution is accurately determined. High yield of oil and gas has been obtained by late drilling in the determined favourable area. The successful practice provides a new method for application of seismic data to geology and a new approach for research of sedimentary microfacies. |
