Study on Optimal Allocation Mode of Produced Water Resources in H Oil Region

With the gradual implementation of the state’s governance of underground overexploited areas and the South-to-North Water Diversion Project, it has become an inevitable trend to raise water resources tax and completely disable self provided water source wells. H oil area is located in Langfang area. According to the local policy requirements, the water source wells will be stopped in the near future, and the water charge will triple. At present, there are 15 water injection stations in the whole plant. If all of them rely on tap water to meet the water injection demand, on the one hand, the use cost of clean water will be greatly increased, on the other hand, the water injection volume will be limited by the local water supply capacity, there is a greater risk of water injection failure, and the effect of oilfield water injection development cannot be guaranteed. Therefore, on the basis of analyzing the current situation of water injection system in H oil area, it is of great significance to determine the potential capacity of produced water resources, plan the adjustment plan of water injection flow direction in the oil area in advance, improve the research of supporting water treatment process and carry out the field implementation work.
