摘要
由于地质条件和资料品质的限制,复杂断块区的三维地震资料反演和储集层预测有较大的难度。给出了我国东部某复杂断块区三维地震反演和储集层预测的技术实例,总结了反演工作经验。详细阐述了实现的策略和技术方案,包括数据的分析与处理(如地震极性的判断、测井曲线规则化和敏感性分析等)、子波提取、拟声波测井曲线的重构、约束波阻抗反演、速度场建立、地质统计随机模拟等,展示了多学科一体化工作的过程。研究结果为该区块的井位部署提供重要依据,对类似地区的地震反演和储集层预测也有重要的借鉴意义。
The seismic inversion and reservoir prediction in complex fault-block areas are hard to make due to complicated geologic conditions and poor quality of seismic data. This paper presents the case of 3D seismic inversion and reservoir prediction of a complex fault-block area in eastern China and reviews the inversion experiences. The practical strategy and technical scheme are elaborated, including data analysis and processing （e.g. judgment of seismic event polarity, regularization of well logs and sensitivity analysis, etc.）, wavelet extraction, reconstruction of pseudo-sonic logs, constrained impedance inversion, velocity field establishment and stochastic simulation of geo-statistics, etc. as a model of multi-discipline integration. The study results can be as an important basis for well deployment in the working area. Other similar areas may take them as an example for reference.
