| 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 |

| 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; ② origin-controlled modeling; ③ multi-stage modeling; ④ choosing 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. |
