常规测井为 AVO 分析提供了基础的资料, 成为联系岩石物理与地震资料的桥梁。然而如果储层存在有复杂的流体系统, 如地层被严重地层流体侵入、电阻率响应低及盐水矿化度复杂等的现象, 则常规测井无法提供高质量的测井资料, 导致得出错误的弹性计算结果, 使 AVO 结果与地震资料不吻合。中国渤海湾地区第三系裂缝性储层复杂, 我们利用常规测井和核磁共振测井与模块地层动态测试相结合的组合仪完成了地层评价和储层描述。研究结果表明岩石物理学家利用上述方法技术可以获得诸如空隙度、渗透率、含水饱和度、束缚流体以及空隙压力等重要的储层参数并进一步综合应用这些结果和以实验室测量数据为基础的岩性分析结果进行在地震域岩石物理研究和 AVO 分析。
Conventional logging provides the foundation for AVO analysis and serves as a bridge between rock physics and seismic data. However, conventional logging can not provide high-quality logging data if there are complex fluid systems in the reservoir, such as formation intrusion by serious formation fluid, low resistivity response and complex salinities, leading to errors The results of the elastic calculations do not match the AVO results with the seismic data. The Tertiary fractured reservoirs in the Bohai Bay region of China are complex. We completed the formation evaluation and reservoir description using a combination of conventional logging and NMR logging and dynamic testing of the formation. The results show that petrophysicists can use these techniques to obtain important reservoir parameters such as porosity, permeability, water saturation, bound fluid, and pore pressure and further integrate these results with laboratory-based measurements Lithologic analysis results are carried out in the seismic area of rock physics and AVO analysis.
