洪积扇作为一种地貌现象,具有其独特的形成环境以及地质构造,对洪积扇储层进行油藏描述技术的实施,主要步骤包括:划分小层并对比分析、精细小层解释、测井四性关系分析、研究精细小层沉积微相、三维地质模型的构造、油藏预测地质模型构造以及分析目标潜力提出挖潜建议等。其中,三维地质模型的构造可以通过洪积扇储层地质建模来完成,洪积扇储层地质建模主要为三维储层地质建模,其内容主要包括准备数据、设计网格、地层层面建模构造、建立储层岩三维相模型以及洪积扇储层三维参数建模等。
As a geomorphological phenomenon, the alluvial fan has its unique formation environment and geological structure, and the implementation of reservoir description techniques for the alluvial fan reservoirs includes the following steps: dividing and analyzing the small layers, interpreting the fine layers, measuring We analyze the four-dimensional relationship of wells, study the fine sedimentary microfacies, the structure of three-dimensional geological model, the construction of the geological model of reservoir prediction and the potential of the target to be proposed. Among them, the three-dimensional geological model can be constructed by means of geological modeling of alluvial fan reservoirs. Geological modeling of alluvial fan reservoirs is mainly geological modeling of three-dimensional reservoirs, and its contents mainly include preparation data, design grid, stratigraphic level Modeling and modeling, the establishment of reservoir rock three-phase model and three-dimensional parameters of alluvial fan reservoir modeling.
