    • A computer-implemented method for determining one or more operating modes for a crude oil displacement system is provided. The crude oil displacement system is arranged to inject an aqueous displacement fluid into one or more reservoirs, each reservoir comprising a porous and permeable rock formation, wherein crude oil and formation water are contained within a pore space of the rock formation. The crude oil displacement system is for use in displacing crude oil from the pore space of the rock formation. The computer-implemented method comprises the steps of receiving measurement data associated with one or more chemical characteristics of the displacement fluid and one or more chemical characteristics of the rock formation, the crude oil and the formation water of the one or more reservoirs, and inputting the measurement data and data representing a predetermined volume of oil into a computer-implemented predictive model. The predictive model is operated so as to generate predicted data indicative of a predicted additional amount of oil, compared to the predetermined volume of oil, that will be displaced by configuring the crude oil displacement system so as to inject the displacement fluid having the chemical characteristics into the one or more reservoirs. On the basis of the predicted data, the one or more operating modes of the crude oil displacement system are determined. A further computer-implemented method employing the predictive model in which predicted data indicative of one or more predicted chemical characteristics of the displacement fluid are generated is also provided. Additionally, a system for configuring a crude oil displacement system is provided.
    • 提供了一种用于确定原油排放系统的一种或多种操作模式的计算机实现的方法。 原油置换系统被布置成将含水置换流体注入到一个或多个储存器中,每个储存器包括多孔和可渗透的岩层,其中原油和地层水被包含在岩层的孔隙空间内。 原油排放系统用于从岩层孔隙空间中排除原油。 计算机实现的方法包括以下步骤:接收与位移流体的一种或多种化学特性相关联的测量数据和一个或多个储层的岩层,原油和地层水的一种或多种化学特征,以及输入 测量数据和表示预定油量的数据转换成计算机实现的预测模型。 操作该预测模型,以产生指示与预定体积的油相比预测的附加量的油的预测数据,其将通过配置原油排出系统而移位,以便注入具有化学特性的置换流体 进入一个或多个储层。 根据预测数据,确定原油排放系统的一个或多个运行模式。 还提供了采用预测模型的进一步的计算机实现的方法,其中产生指示位移流体的一种或多种预测化学特性的预测数据。 另外,提供了一种用于配置原油排放系统的系统。
