The near field fluid mechanics of SAGD wells

RGL油藏管理公司(RGL)是用于沥青和稠油开采的防砂和配流技术的行业领先者。他们的开槽衬垫技术被用于蒸汽辅助重力排水(SAGD)技术，用于现场提取沥青。开槽衬垫被用来将蒸汽引入储油层，以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。生产井中的开槽衬管还用于最大限度地减少出砂量，同时最大限度地增加石油流量。这两口井都存在多种失效机制，包括腐蚀、冲刷和结垢，在设计开槽衬管时需要考虑这些因素。该项目的目的是提供关于注入井和生产井的近井(&lt；1M)流体力学的更详细的了解和信息。这些信息将被用来制定更强大的设计程序以及减轻失效机制。这项研究将采取两种方法。使用模型流体/条件和真实流体/条件的实验研究将阐明存在的流动现象，并提供关于多种不同条件下的流场的基本和详细的数据。使用计算流体力学(CFD)的数值模型将使用来自实验的验证数据来开发，以提供对该流场的进一步了解。然后，这些将被用作优化过程的一部分，以提供关于RGL开槽衬垫技术的设计方向的明确信息。

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.
