地震沉积学在喇嘛甸油田扶余油层中的应用
|
摘要
针对喇嘛甸油田扶余油层勘探初期"井少,地震资料全"的特点,运用地震沉积学的方法和技术,解决了井资料缺乏对层序划分以及沉积相研究所带来的困难。应用表明,研究区内90°相位地震资料使振幅与岩性测井曲线形成了较好的对应关系,且提高了解释精度;地层切片技术能识别出地震剖面上的三个四级层序SQ1、SQ2、SQ3的层序边界。通过地震资料与测井资料相结合,刻画出扶余油层三个四级层序的沉积相。通过对沉积相的分析,认为优势相带为分流河道微相和决口扇微相;且研究层段经历了三角洲平原到三角洲前缘的水进沉积演化过程。
Aiming at the following characteristics of Fuyu oil layer in Lamadian oilfield,i.e.,the sparseness of wells,the denseness of the seismic data,the difficulty is solved which are sequence division and the research of sedimentary facies because of the sparseness of wells by using the method and the technology of Seismic sedimentology.The results show seismic amplitudes can be correlated to log lithologies and the interpretation accuracy can be improved by using 90°-phase seismic data.The technique of stratal slices can identify the boundary of three 4th-order sequences(SQ1,SQ2,SQ3)in seismic profiles.The sedimentary facies of 4th-order sequence have been characterized by combining seismic data with lithologic log data.Through analysing the sedimentary facies,the dominant sedimentary facies are distributive river and flood land are obtained;and at the same time the target zone mainly experienced from deltaic plain to deltaic-front are known.
