摘要
利用以波阻抗反演为基础的储层反演技术在南阳凹陷张店油田的应用,预测了南阳凹陷牛三门周缘薄砂层(厚度大于8 m)平面几何形态、孔隙度、渗透率及含水饱和度等参数,进而对储层特性进行精细描述,应用地震地层学研究理论,综合分析了该区有利勘探目标,提出了南75、南76和南79井位部署建议,取得了良好的地质效果。这说明在滚动勘探开发阶段的老油田,利用储层参数反演寻找有利圈闭,提供钻探目标的方法是有效的。
Through the application of reservoir inversion based on wave impedance inversion of Zhangdian oilfield in Nan-yang sag, the plane geometry, porosity, permeability and water saturation of the periphery of thin sand in Niusan-men of Nanyang sag has been predicted, and then a detailed description of reservoir characteristics has been made. Based on the theory of seismic stratigraphy, and after comprehensive analysis on favorable exploratory targets, geometric arrangement of Nan 75, Nan 76 and Nan 79 has been suggested. The good geological result shows that using reservoir parameter inversion technique to find out favorable traps and provide drilling target is effective in maturing field during rolling exploratory development stage.
