摘要: A method for matching production history to flow simulations includes identifying a plurality of parameters that control an objective function measuring the mismatch between a flow simulation response in a parameter subspace and a production history. A value is calculated for an objective function and for a static measurement at each of a plurality of experiments in the parameter subspace. These results are used to develop a mathematical relationship between one or more static measurements and the objective function. During subsequent adjustment of the simulation model, a target window in the objective function is identified, and flow simulations are performed for each modified model that is predicted from the static geologic measurement to produce an objective function within the window. An objective function of each flow simulation to the production history is calculated and the procedure is iterated until the objective function is within a target range.

摘要翻译: 用于将生产历史与流程模拟相匹配的方法包括识别控制参数子空间中的流动模拟响应与生产历史之间的不匹配的目标函数的多个参数。 在参数子空间中的多个实验的每一个处,针对目标函数和静态测量计算值。 这些结果用于开发一个或多个静态测量与目标函数之间的数学关系。 在仿真模型的后续调整过程中,识别目标函数中的目标窗口,并对从静态地质测量预测的每个修改后的模型进行流模拟,以在窗口内产生目标函数。 计算每个流程仿真到生产历史的目标函数,并重复该过程,直到目标函数在目标范围内。
