摘要
地震沉积学是一种利用地震资料进行沉积演化研究的新思路和新方法。在层序地层及岩心、钻井测井沉积微相研究的基础上，通过正演分析明确地震响应与砂岩厚度及岩性组合的相互关系，应用90°相位转换、地震属性分析和分频解释等技术手段，在英台-大安地区姚家组二三段开展了地震沉积学研究。结果表明，应用地震沉积学技术方法编制的沉积微相图，能够准确地刻画出沉积微相边界。应用该方法能够有效地指导英台-大安地区的油气勘探。
Seismic sedimentology is a new emerging idea or method for sedimentary evolution researches using seismic data. Based on the researches on sequence stratigraphy, core, drilling, logging, and sedimentary microfacies, the relationships between seismic response and sandstone thickness and lithological association are established by forward analysis. Moreover, the researches on seismic sedimentology are carried out for Yao No. 2 and No. 3 Members in Yingtai-Da＇ an area by means of the technologies of 90°phase conversion, seismic attribute analysis and frequency-division interpretation etc. The results show that the sedimentary micro-facies diagrams compiled by seismic sedimentology technology can accurately delineate the boundaries of the sedimentary microfacies and furthermore can provide an effective guidance for the petroleum exploration in Yingtai-DA ＇ AN area.
