Water is the source of life, and one of the solutions to the lack of water resources is to increase the recycling rate of water. With the extension of the mining time, the oil industry has gradually increased the amount of water produced by water injection development. Treating the oil field produced water for reinjection is a way to recycle water. If the produced water is unreasonably treated, reinjected and discharged, not only will the oilfield surface facilities fail to operate normally, but it will also cause harm due to stratum blockage, and at the same time will cause environmental pollution and affect the safety of oilfield production.

In recent years, through the introduction and digestion of foreign advanced technology and independent innovation, domestic oilfields have made great achievements in the utilization of produced water resources. However, for low-permeability oilfields, it is difficult for the current oilfield wastewater treatment stations to stably meet the water quality requirements of low-permeability oil layers, especially ultra-low-permeability oil layers, for reinjection water. Since the reserves of low-permeability reservoirs in my country account for 60% to 70% of the total reserves, it is the main basis for increasing reserves and production for a long time in the future. The main method of low-permeability reservoir development technology is water injection, so advanced low-permeability reservoirs The oil layer reinjection water treatment program is very worthy of promotion and application.

The "low-permeability/ultra-low-permeability oilfield wastewater reinjection treatment method" independently developed by our company has been successfully applied to the three major oilfield systems of PetroChina, Sinopec, and Shaanxi Yanchang Oilfield, with more than 300 projects, and the total daily processing volume of the current operating projects of the oilfield More than 800,000m3/d.

Since 2011, it has provided customers with hundreds of skid-mounted solutions for applications in Daqing Oilfield, Changqing Oilfield, Yanchang Oilfield, Huabei Oilfield, Jiangsu Oilfield, Xinjiang Oilfield, Zhejiang Oilfield, etc.

According to the scale of oilfield reinjection water projects, we provide customers with overall solutions, including engineering design, installation, commissioning and other services; we also provide customers with skid-mounted solutions, which are used in oilfield reinjection projects with small water volumes, and are also large-scale Provide reference for the trial operation and parameter design of the project.
