【摘要】 为了提高随机建模的精度 ,降低模拟实现中的不确定性 ,在建模过程中应采取以下地质约束原则 :等时约束建模 ,成因控制建模 ,多步建模 ,应用地质模式选择随机模拟方法 ,应用目标区多学科信息或原型模型确定统计特征参数 ,应用确定性信息限定随机模拟过程。在此基础上 ,提出了地质约束条件下的储层随机建模流程 ,并以长庆安塞油田坪桥水平井区储层随机建模为例 ,进一步阐述了地质约束随机建模的思路和方法更多还原

【Abstract】 The principles of geological constraints on reservoir stochastic modeling are discussed. In order to decrease the uncertainties in simulation realizations, the following geological constraint principles must be abided: ①equivalent\|time constrained modeling; ②origin\|controlled modeling; ③multi\|stage modeling; ④choosing optimum stochastic simulation methods using geological model; and ⑤determining statistical character parameters using proto\|model. A new flowchart of reservoir stochastic modeling under geological constraints is proposed. A case study of stochastic modeling of Chang 6 reservoir of Triassic in Pingqiao horizontal well region of Changqing oilfield is used to further certify the methods of geological constrained stochastic modeling.更多还原
