| 摘 要： | 非常规油气藏地质建模与数值模拟是通过对地质、地震、油藏综合研究,建立储层精细地质模型。首先建立构造模型,同时运用地震反演的成果结合单井岩相数据建立岩相模型,利用钻井泥浆漏失、油气田和单井的实际生产情况和微地震监测,描述油气藏内发育的天然裂缝和人工压裂裂缝,最终利用岩相模型控制建立孔隙度和饱和度等属性模型,为数值模拟提供能够反映与实际地质情况相符的三维油气藏粗化地质模型。在此模型的基础上,进行生产历史拟合、产量预测,并制定合理的开发方案。

| Abstract: | Unconventional hydrocarbon reservoir modeling and numerical simulation is through geological, seismic and hydrocarbon reservoir integrated research to model precise reservoir geological model. Structural modeling at first, simultaneously use seismic＇ inversion result combined with single well lithofacies data carry out lithofacies modeling, using drilling hole mud loss, oil gas field and single well production and microseismic monitoring, describe natural fissures and artificial fracturing fissures developed in reservoir, finally using lithofacies model to control and model porosity and saturation attribute models, provide numerical simulation with 3D hydrocarbon reservoir upsealing geological model accord with actual geological conditions. Based on this model, can carry out production history fitting, output prediction, and set down rational development project. |
