The invention discloses a geologic modeling method for a continental shale oil reservoir. Comprising the steps that in a target area, a corresponding lithofacies combination model is constructed for target continental facies shale; based on the lithofacies combination model, constructing a lithofacies model and a discrete fracture network model; taking the lithofacies model as a constraint condition, combining with the discrete fracture network model, and adopting a sequential Gaussian stochastic simulation method to construct a reservoir parameter model; through the method, a model with higher applicability and higher precision can be established, and a powerful basis is provided for subsequent continental facies shale oil reservoir geological research. 本发明公开了一种陆相页岩油储层地质建模的方法；包括：在目标区域内，针对目标陆相页岩构建对应的岩相组合模型；基于岩相组合模型，构建岩相模型和离散裂缝网络模型；将岩相模型作为约束条件，结合离散裂缝网络模型，采用序贯高斯随机模拟法构建储层参数模型；通过该方法能够建立适用性更强，精度更高的模型，为后续陆相页岩油储层地质研究提供有力依据。
