摘要

在油田储层工程中积极使用综合建模,促使人们研究如何克服实际应用中的问题。通常情况下,三维流体力学模型被用作描述储油层流体流动特征的组成部分。该模型的缺点是计算复杂度高,初始数据可靠性低。因此,本研究的目标是构建一个没有这些缺点的储层-井综合模型,并验证其适当性。文章提出了一个综合模型,用于油田开发的快速决策以及井间空间特征的分析,该模型不需要事先了解储层信息。该综合模型基于电容-电阻分析模型(CRM),考虑了生产井的停产期。石油流速采用科瓦尔法计算。油井中的压力分布采用类似于 tNavigator 软件中使用的相关性进行计算。使用基于 D-CRMP 的综合模型得出的计算结果与 tNavigator 中的计算结果进行了比较。

Integrated model "reservoir-well" based on D-CRMP
The active use of integrated modeling in reservoir engineering of oil fields has led to research to overcome the problems of its practical application. Typically, a 3D hydrodynamic model is used as a component characterizing the fluid flow in the reservoir. The downsides of the model are high computational complexity and low reliability of the initial data. Therefore, the objectives of the study are to construct an integrated reservoir-well model that does not have these drawbacks and to verify its adequacy. The article presents an integrated model for fast decision-making in the development of oil fields, as well as for analysis of the characteristics of the inter-well space, which doesn't require prior information about the reservoir. The integrated model is based on a representation of the analytical capacitance-resistance model (CRM), which considers shutdown periods of production wells. Oil flow rates are calculated using the Koval method. The pressure distribution in wells is calculated using a correlation similar to that used in the tNavigator software. A comparison was made between the calculation results obtained using the integrated model based on D-CRMP and the calculations in the tNavigator.
