Polymer/Low Saline Water Injection for Medium-Heavy Oil Recovery

注水是最常见的采油方法，事实上，在许多油田成功地进行了数千次注水开发。这是一项经过验证的技术，即使在低采收率的情况下，它也是可靠的、低风险的、在经济上成功的。自20世纪40年代S以来，大部分认识空白已经得到解决，但优化其性能，并将其推广到中、稠油碳酸盐岩油藏是一个重要的研究领域，但受到的关注较少。低矿化度注水(Smart Water)是石油行业最新的研究热点领域。这一过程在其简单性和效果上是独特和独特的。挪威研究人员进行的早期实验室规模试验(仅限于轻质油、渗吸和常规水驱研究)表明，原油采收率增加了很多。这一拟议项目的主要目标是测试、应用和优化“聚合物/低矿化度注水”新工艺，以提高萨斯喀彻温省和艾伯塔省碳酸盐岩油藏的中/稠油采收率，了解和描述多孔介质中流体流动/相互作用的物理过程，增加新的储量，减少过量产水对环境的影响，并为新工艺下聚合物/低矿化度注水工艺开发中/稠油碳酸盐岩油藏制定指导方针。

Waterflooding is the most common oil recovery methods, and indeed, thousands of successful water floods are operated in many oil fields. It is a proven technology, which is reliable, low-risk, and economically successful even at low recovery levels. Most of the knowledge gaps have been solved since the 1940's. However, optimizing its performance and extending its application specifically to medium/heavy oil carbonate reservoirs are important research areas, which have received less attention. Low salinity water injection (Smart Water) is the most recent research focus area by the oil industry. This process is unique and distinctive in its simplicity and effects. The early laboratory scale tests conducted by Norwegian researchers (light oil, imbibition, and conventional waterflooding studies only) showed considerable incremental oil recovery. The main objectives of this proposed project is to test, employ and optimize the new process " Polymer/Low Salinity Water Injection", for improving medium/heavy oil recovery from Saskatchewan and Alberta carbonate oil reservoirs, to understand and describe the physics of fluid flow/interaction in porous media, to add new reserves, to reduce the environmental impact of excessive water production and to derive guidelines for developing medium/heavy oil carbonate reservoirs under the new process polymer/low salinity water injection process.
