Oilfield reinjection water ultraviolet sterilizer
Oilfield reinjection water ultraviolet sterilizer
Product details
The combination of ultraviolet disinfection equipment for oilfield reinjection water and regular impact dosing of chemical disinfectants has become the most economical means of avoiding microbial contamination in oilfield water injection, which can simultaneously kill aerobic and anaerobic bacteria. The use of ultraviolet disinfection equipment for oil injection water also greatly reduces the frequency of chemical drug usage, thereby reducing the cost of managing and transporting chemical drugs. To ensure that the water quality of oilfield injection meets the requirements, a series of process flows are usually required. Combining the sterilization of oilfield reinjection water by ultraviolet sterilizers with other water treatment processes is an effective means. The ultraviolet disinfection system for petroleum reuse water can serve as the final step in the water treatment process; Avoid secondary biological pollution of water caused by other processes.
2、 Advantages of using UV disinfection equipment for oilfield reinjection water:
The UV disinfection equipment for oilfield reinjection water has a compact and modular structure, and is easy to install in existing pipelines, making installation very convenient and simple. The impact dosage of chemical drugs does not require complex monitoring equipment, but if only chemical disinfectants are used as the main disinfection method, precise monitoring equipment must be equipped to control it. Bacterial control has become an important issue in the oil and gas industry. Improper sterilization can have significant consequences, including hydrogen sulfide gas acidification of reservoirs, microbial induced corrosion, or loss of stability of liquids during stimulation.
3、 Water quality standards for oilfield reinjection water treated with ultraviolet disinfection equipment:
1. Sulfate reducing bacteria (SRB)<102 cells/ml
2. Saprophytic bacteria (TGB) at a concentration of 102 cells/ml
3. Iron bacteria (FB)<102 cells/ml
