通过对西非深水海底扇沉积相模型研究建立地质概念模型,在此基础上建立高精度的等时地层格架和沉积相的划分,精确的井震综合标定、精细的层位解释和断层解释为建模提供构造模型;地震属性向地质特征的转换弥补了井间信息的不足,对地质统计参数进行了估计,根据沉积相类型选择随机建模方法,以地震信息为约束建立砂体骨架模型。以尼日尔工区为例采取井震结合的方法进行储层地质建模研究。
Based on the study of the sedimentary facies model of deep-sea submarine fan in West Africa, a geological conceptual model was established. On this basis, the establishment of high-precision isochronal stratigraphic framework and division of sedimentary facies, accurate calibration of wellbore seismicity, fine horizon interpretation and fault interpretation Modeling provides the structural model. The conversion of seismic attributes to geological features makes up for the lack of cross-well information. The geological statistics parameters are estimated. Based on the sedimentary facies type, stochastic modeling method is selected to establish the sand body skeleton model with seismic information as constraint. Taking the Niger area as an example, a well-seismic combination method is used to study reservoir geological modeling.
