摘要

通过地震反射的外部形态,内部结构以及地震反射参数的分析,对春光区块沙湾组一段第三砂层组的地震相进行了划分命名。在研究区我们共识别出前积地震相,丘状体,复合丘状体,下凹和充填状等类型。结合钻井资料将地震相转化为沉积相,对沙一段第三砂层组的沉积相进行分析,对预测岩性圈闭有着非常重大的意义。
Based on the analysis of seismic reflection external shape,internal reflection texture and seismic reflection parameters,seismic facies of the third sand set in 1st member of Shawan formation were divided and named.Four types of seismic facies in the research area were recognized,including foreset,moundy,multiple moundy and filling seismic facies.Combined with drilling and seismic data,seismic facies can be transformed into sedimentary facies.Then the lithologic trap can be identified based on the sediment system analysis of the third sand set in 1st member of Shawan formation,which is very significant.
