Abstract

Reservoir simulation is of interdisciplinary research, including petroleum engineering, mathematics, and computer sciences. It studies multi-phase (water, oil and gas) flow in porous media and well modelling. The latter describes well behavior using physical and mathematical methods. In real world applications, there are many types of wells, such as injection wells, production wells and heaters, and their various operations, such as pressure control, rate control and energy control. This paper presents commonly used well types, well operations, and their mathematical models, such as bottom hole pressure, water rate, oil rate, liquid rate, subcool, and steam control. These are the most widely applied models in thermal reservoir simulations, and some of them can even be applied to the black oil and compositional models. The purpose of this paper is to review these well modelling methods and their mathematical models, which explain how the well operations are defined and computed. We believe a detailed introduction is important to other reseachers and simulator developers. They have been implemented in our in-house parallel thermal simulator. Numerical experiments have been carried out to validate the model implementations and demonstrate the scalability of the parallel thermal simulator.

热储模拟中的井建模方法

油藏模拟是石油工程、数学、计算机科学等多学科交叉的研究领域。研究多孔介质中多相(水、油、气)流动和井模型。后者使用物理和数学方法描述井的动态。在实际应用中，有许多类型的井，如注水井、生产井和加热器，以及它们的各种操作，如压力控制、速率控制和能量控制。本文介绍了常用的井型、井作业及其数学模型，如井底压力、水量、油量、液量、过冷量和蒸汽控制。这些是热储层模拟中应用最广泛的模型，其中一些模型甚至可以应用于黑油和成分模型。本文的目的是回顾这些井建模方法及其数学模型，这些模型解释了如何定义和计算井作业。我们相信详细的介绍对其他研究人员和模拟器开发人员很重要。它们已经在我们内部的并行热模拟器中实现。通过数值实验验证了模型的实现，验证了并行热模拟器的可扩展性。

期刊介绍： OGST - Revue d''IFP Energies nouvelles is a journal concerning all disciplines and fields relevant to exploration, production, refining, petrochemicals, and the use and economics of petroleum, natural gas, and other sources of energy, in particular alternative energies with in view of the energy transition. OGST - Revue d''IFP Energies nouvelles has an Editorial Committee made up of 15 leading European personalities from universities and from industry, and is indexed in the major international bibliographical databases. The journal publishes review articles, in English or in French, and topical issues, giving an overview of the contributions of complementary disciplines in tackling contemporary problems. Each article includes a detailed abstract in English. However, a French translation of the summaries can be provided to readers on request. Summaries of all papers published in the revue from 1974 can be consulted on this site. Over 1 000 papers that have been published since 1997 are freely available in full text form (as pdf files). Currently, over 10 000 downloads are recorded per month. Researchers in the above fields are invited to submit an article. Rigorous selection of the articles is ensured by a review process that involves IFPEN and external experts as well as the members of the editorial committee. It is preferable to submit the articles in English, either as independent papers or in association with one of the upcoming topical issues.
