摘要
东营凹陷辛154井区在第三系沙河街组沙三中沉积时期沉积了浊积扇及其前缘砂体,构造和岩性圈闭都具有很好的成藏条件。通过叠后地震资料处理提高目的层的信噪比,使地震资料的振幅得到真正的恢复。利用多井约束地震反演对地震数据体进行处理。综合分析测井、构造解释和岩屑录井等资料对浊积扇及其前缘砂体储层特征进行了定量描述,并结合地震资料多井测井约束反演技术,对辛154井区沙三中的隐蔽油气藏进行了综合描述。
The turbidite fan and front sand in the third segment of the Tertiary Shahejie Formation in Xin 154 survey area are favorable regions both structurally and lithologically for hydrocarbon concentration. To characterize the subtle reservoir in the third segment of Shahejie Formation, we firstly improved the resolution of the target and recovered the true amplitude of seismic data by poststack data processing techniques. Multi-well-constrained seismic inversion was then implemented on the data. And finally, comprehensive quantitative characterization of the turbidite fan and front sand were carried out on logging, structural interpretation, and core data.
