【摘要】 地震岩石物理学是研究岩石岩性、流体和岩石弹性参数之间关系的学科,在运用地震资料开展储层和油气预测工作中,是测井岩石物理与地震资料进行储层预测和烃类检测的桥梁和纽带。针对叠后波阻抗属性无法识别渤海A油田明下段储层的流体性质问题,利用流体替换、正演模拟技术探索不同流体类型、含水饱和度、孔隙度变化对测井曲线响应及地震振幅响应特征的影响,指导后续的储层研究和烃类检测。地震岩石物理研究思路和方法在渤海同类型的储层预测和烃类检测中具有推广意义。更多还原

【Abstract】 The objective of seismic rock-physics is to study the relationship between lithology,fluid and elastic parameters of rocks.This technology has the advantage to establish the basic criteria for reservoir and hydrocarbon prediction upon seismic data.In the oilfield Bohai A,the inversion of post-stack impedance is not enough to identify the reservoir fluid properties and the changes in fluid types.Water saturation and porosity have effect on the response of well data and seismic amplitude.In order to know better about the effect,we use fluid replacing and forward simulation technology to guide the reservoir research and hydrocarbon testing.The technology can be promoted to the oilfields with similar reservoirs.更多还原
