地震属性分析在南堡凹陷的应用

Application of seismic attribute analysis in Nanpu Sag

南堡凹陷具有多凸、多凹、多物源、多旋回、多断裂的特点,具备了良好的地层—岩性圈闭发育条件,因此需要充分利用地震资料丰富的地质信息,同时结合地质、钻井等资料对地震资料进行精细构造、储层、流体性质等综合解释。本文实例充分展示了GeoEast解释系统的地震属性分析方法在南堡凹陷低序级断层解释、砂岩储层预测和油气检测等方面的良好应用效果,为勘探开发井位部署提供了有效的技术支撑。

Nanpu Sag is characterized by multi-convexity,multi-concave,multi-source,multi-cycle,and multi-fault,and has good development conditions of stratigraphic-lithologic traps.So it is necessary to fully excavate and utilize abundant geological information on seismic data.At the same time,combined with geological and drilling data,seismic data are comprehensively interpreted for structure,reservoir,and fluid properties.This paper demonstrates fully successful applications of distinctive interpretation approaches provided by GeoEast in the middle-shallow faults interpretation,the middle-deep reservoirs prediction,and the hydrocarbon detection in Nanpu Sag,which provides effective technical supports for the well location deployment in the future hydrocarbon exploration and development.
