Solution Advantages
Specific Microbial Agent Adaptation: Targeting the characteristics of the produced water in this block, a highly efficient functional microbial agent was formulated and screened, achieving an inhibition rate of over 99% against sulfate-reducing bacteria and increasing polymer solution viscosity by 50%. It is perfectly suited to the harsh temperature and salinity environment of the oil reservoir.
Integrated Process Advantages: Utilizing an integrated "biochemical treatment + membrane separation" process, it eliminates the need for constructing large sedimentation tanks, reducing the footprint by 40% compared to traditional processes. The treated effluent consistently meets the A1 grade standard for reinjection water.
Long-Term Stability Advantages: The system has operated stably for three consecutive years, with effluent quality fluctuations of less than 5%. Its resistance to shock loads is twice that of traditional processes, ensuring compliance even under extreme water quality conditions.
Application Results: This technology has covered all 12 chemical flooding blocks in the oilfield, treating over 10 million cubic meters of produced water annually, reducing tap water consumption by 5 million cubic meters annually, improving polymer flooding efficiency by 15%, and generating over 200 million yuan in annual benefits.
