The near field fluid mechanics of SAGD wells

RGL油藏管理公司（RGL）在沥青和稠油采油防砂和配流技术方面处于行业领先地位。他们的开槽尾管技术被用于蒸汽辅助重力排水（SAGD）技术中，用于沥青的原位开采。使用开槽尾管将蒸汽引入储层，通过加热来降低沥青的粘度。然后可以通过第二口井生产低粘度沥青。生产井中的缝尾管也用于在最大限度地提高产油量的同时最大限度地减少出砂。两口井都存在腐蚀、侵蚀和结垢等多种失效机制，在设计开槽尾管时需要考虑这些因素。该项目的目的是为注入井和生产井的近井（<1m）流体力学提供更详细的了解和信息。这些信息将用于开发更强大的设计程序以及减少故障机制。这项研究将采取双重方法。使用模型流体/条件和实际流体/条件的实验研究将阐明当前的流动现象，并提供一些不同条件下流场的基本和详细数据。使用计算流体动力学（CFD）的数值模型将利用来自实验的验证数据来开发，以进一步了解该流场。这些数据将作为优化过程的一部分，为RGL开槽尾管技术的设计方向提供明确的信息。

RGL Reservoir Management (RGL) is an industry leader in sand control and flow distribution technology used in bitumen and heavy oil recovery. Their slotted liner technology is used in the steam assisted gravity drainage (SAGD) technique for the in situ extraction of bitumen. A slotted liner is used to introduce steam into the reservoir to reduce the viscosity of bitumen via heating. The low viscous bitumen can then be produced via a second well. The slotted liner in the production well is used also to minimize sand production while maximizing oil flow. A number of failure mechanisms including corrosion, erosion and scaling are present in both wells and these need to be taken into account when designing a slotted liner. The aim of the project is to provide more detailed understanding and information on the near well (<1m) fluid mechanics of both the injection and production wells. This information will be used to develop a stronger design procedure as well as mitigate failure mechanisms. The research will take to twofold approach. An experimental investigation using both model fluids/conditions and real fluids/conditions will elucidate the flow phenomenon present and provide basic and detailed data on the flow field on a number of different conditions. Numerical models using computational fluid dynamics (CFD) will be developed using the validation data from the experiments to provide further insight into this flow field. These will then be used as part of an optimization process to provide explicit information on design directions for RGL slotted liner technology.
