The three types of microorganisms present in oilfield reinjection water pose the most direct threat to oilfield production:

·Sulfate-Reducing Bacteria (SRB): Under anaerobic conditions, SRB metabolize to produce H2S, which directly leads to electrochemical corrosion of equipment and pipelines, causing pitting and ultimately perforation and leaks.
·Saprophytic Bacteria (TGB): They form large amounts of slime and biofilm, which adhere to pipe walls and formation pores, clogging the formation, reducing injection efficiency, and providing a habitat for anaerobic bacteria like SRB.
·Iron Bacteria (IB): They oxidize ferrous iron in water to ferric iron, forming ferric hydroxide precipitates. These precipitates, combined with biofilms, further exacerbate pipeline and formation blockages and deteriorate water quality.
Currently, oilfields widely use ultraviolet disinfection to control these three microorganisms.
Ultraviolet disinfection
In oilfield reinjection water treatment systems, ultraviolet disinfection devices are typically not used as standalone units, but rather integrated at the end of the treatment process. They serve as the final sterilization barrier before water quality refinement and injection.
Process flow: Produced water - oil/impurity removal (coagulation, flotation) → filtration (sand filtration, walnut shell filtration, etc.) → fine filtration (membrane filtration, etc.) → ultraviolet disinfection - injection well
China's petroleum and natural gas industry standard SY/T5329-2012, "Water Quality Indicators and Analysis Methods for Injection Water in Clastic Reservoirs," clearly defines microbial indicators for reinjection water in formations of varying permeability.
· Sulfate-reducing bacteria (SRB): No more than 10 cells/mL
· Saprophytic bacteria (TGB): No more than 100 cells/mL
· Iron bacteria (IB): No more than 100 cells/mL
Innovations in ultraviolet disinfection technology for oilfield reinjection water
Synergistic disinfection mode: "UV + low-dose chemical disinfectant"
As the main sterilization unit, ultraviolet rays are responsible for inactivating more than 99% of microorganisms, quickly and efficiently reducing the bacterial base number to an extremely low level at the outlet of the treatment station.
而后端仅需辅以低浓度(可能是传统用量的10%-20%需要根据管网情况确定)长效的化学抑菌剂供管网中的持续抑制能力,防止微生物复活和二次滋生。
Clear Medium Pressure UV Disinfection System
The ONYX-Clear-SZ in-line medium-pressure UV sterilizer utilizes medium-pressure multi-spectral UV lamps to not only destroy DNA/RNA but also intracellular enzymes and proteins, resulting in more thorough sterilization. It is designed to disinfect and degrade toxic micropollutants in water, including NDMA, 1,4-dioxane, endocrine disruptors (EDCs), pesticide residues, cyanobacterial toxins, GSM (geosmin), and 2-MIB (dimethylisoborneol).
In addition, combining oxidants such as O₃ and H₂O₂ with UV light, such as UV-O₃ and UV-H₂O₂ processes, can be used to oxidatively remove recalcitrant substances and organic matter, such as CC14 and polyaminobiphenyls, from wastewater.
Extrem Medium Pressure UV Disinfection System
The ONYX-Extrem-GY medium-pressure series is a compact medium-pressure UV reactor capable of treating large water volumes. It can be used in applications where space is limited and water quality, taste, flavor, or odor are critical.
It meets the water disinfection needs of clean production applications such as protein purification, amino acid analysis, biomacromolecule analysis, cell culture, and DNA/RNA extraction and purification.
It is suitable for applications in power plants, cooling water circulation, pharmaceuticals, and life sciences.
ZL UV Disinfection System
The ONYX-ZL-SY series features a pipeline-type design with inlet and outlet flange connections. Made of high-strength, corrosion-resistant 304/316L stainless steel, it is fully enclosed and compact.
Both the interior and exterior are electropolished, utilizing UV reflection from the reactor's inner wall to enhance UV intensity and ensure effective disinfection.
The ONYX-ZL-SY series incorporates innovative technologies, including automated mechanical cleaning and CFD flow simulation, to reduce costs and significantly simplify operation and maintenance.
COG Ceramic Plate CD Ozone Generator
The COG series ozone generators feature a built-in ModuOzone® high-concentration ozone discharge chamber and a dedicated high-frequency digital power control drive system. The discharge chamber utilizes high-purity alumina ceramic, features ultra-fine-gap high-frequency discharge, and features efficient water or air cooling to ensure optimal ozone output concentration and efficiency. The equipment integrates a maintenance-free, high-efficiency air compressor and a high-purity oxygen production system, making it suitable for a variety of applications. The COG series ozone generators feature an integrated pressure regulating valve, flow meter, and LCD touchscreen, allowing for adjustable ozone concentration and output levels. The equipment boasts a compact structure, simple operation, easy installation, and ease of maintenance, making it suitable for a wide range of applications, including water treatment, deodorization, decolorization, pharmaceutical manufacturing, wastewater treatment, and food processing.
