潜江凹陷建新地区地震储层预测研究

A Study of Seismic Reservoir Prediction for Jianxin Area in Qianjiang Depression

以古地貌分析、砂体展布特征为指导,开展了潜江凹陷建新地区多种技术手段的地震储层预测研究。结果表明,振幅类与波形类属性是该区的敏感性参数,并且通过本地区的岩石物理分析,认为波阻抗也能较好地区分储层;在刻画储层展布形态的同时与构造相叠合落实了多个构造-岩性圈闭,进一步明确该区构造-岩性油藏的勘探潜力。

On the basis of the analysis of ancient landform and distribution characteristics of sand bodies, this paper launches the research of seismic reservoir prediction for Jianxin Area in Qianjiang Depression by means of multiple technologies. The research result shows that the attributes of amplitude species and waveform species work as sensi- bility parameters in Jianxin. The analysis of its petrophysics proves that wave impedance can also be used to distin- guish reservoir. Multiple structure--lithologie traps are confirmed by overlapping its reservoir distribution form with tectofacies, which further indicates their oil exploration potential.
