| 摘 要： | 缝洞型碳酸盐岩储层多样多期的地质成因和内部强烈的非均质性,使得常规建模手段难以应用于实际工作中。结合地质体特征和地震相,运用聚类分析技术实现缝洞集合体的几何结构建模；针对缝洞型碳酸盐岩测井资料少、储层内部结构复杂和非均质强的特征,将地质统计学地震反演技术用于储层岩相和孔隙度建模工作中,针对塔里木盆地典型区块缝洞集合体建立静态模型,实现其定量地震描述；进一步利用单井与井组内动态数据,修正缝洞体的规模、边界和连通性,研究成果指导了基于缝洞集合体井位的高效部署、高效开发工作。

| Abstract: | Various multi-stage seismic genesis and strong interior heterogeneity of fracture-cavity carbonate reservoir makes conventional modeling means difficult to be used in practice. Combining with the characteristics of geologic body and seismic facies, clustering technique is used to build the geometric model of fracture-cavity aggregate. Focused on few useful well logs, complicated structure and strong heterogeneity of interior reservoir, geostatistical seismic inversion is used to build reservoir lithofacies model and porosity model. Static model is built for fracture-cavity aggregate in typical blocks of Tarim Basin, to fulfill quantitative seismic characterization. Furthermore, the size, boundary and connectivity of fracture-cavity aggregate model could be modified by dynamic data from single well and multiply wells. The research findings can efficiently guide the well design and development work. |
