Nowadays, water savings on industrial plants have become a significant concern for various plants and sections. It is vitally essential to propose applicable and efficient techniques to retreat produced water from onshore and offshore production units. This paper aimed to implement the PFF (Photo Fenton Flotation) method to optimize the water treatment procedure, as it is a two-stage separation technique. The measurements were recorded for the HF (hydraulic fracturing) and CEOR (chemically enhanced oil recovery) methods separately to compare the results appropriately. To assure the efficiency of this method, we first recorded the measurements for five sequential days. As a result, the total volume of 2372.5 MM m³/year of water can be saved in the HF process during the PFF treatment procedure, and only 20% of this required fresh water should be provided from other resources. On the other hand, the total volume of 7482.5 MM m³/year of water can be saved in CEOR processes during the PFF treatment procedure, and only 38% of this required fresh water should be provided from other resources. Therefore, the total water volume of 9855 MM m³ can be saved each year, indicating the efficiency of this method in supplying and saving the water volume during the production operations from oilfield units.

当前页岩油藏不同生产作业中水回用管理的挑战与进展

如今，工业厂房的节水已成为各个工厂和部门的重要关注点。提出适用且有效的技术来回收陆上和海上生产单元的采出水至关重要。本文旨在实施 PFF（Photo Fenton 浮选）方法来优化水处理程序，因为它是一种两级分离技术。分别记录 HF（水力压裂）和 CEOR（化学强化采油）方法的测量结果，以适当比较结果。为了确保这种方法的效率，我们首先记录了连续五天的测量结果。结果，总体积为 2372.5 MM m ³在 PFF 处理过程中，HF 工艺可以节省 1/年的水，而所需的淡水中只有 20% 应从其他资源中提供。另一方面，在 PFF 处理过程中，CEOR工艺可以节省7482.5 MM m ³ /年的总水量，而这所需的淡水中只有 38% 应从其他资源中提供。因此，每年可节约总水量9855 MM m ³，说明该方法在油田装置生产作业过程中补给和节约用水量的有效性。
