2020 CNPC Great Wall Drilling Oil Sludge Treatment Recycling Environmental Protection Equipment Customization Project
Customer Background:
CNPC Great Wall Drilling, a leading domestic oil & gas field engineering service company, faced environmental compliance pressure for oil sludge treatment at drilling sites. They required customized efficient oil sludge recycling equipment meeting hazardous waste treatment standards.
Core Requirements:
Equipment must achieve oil sludge minimization and resource recovery with post-treatment solid waste moisture content ≤15%, meeting national hazardous waste disposal standards;
Adapt to outdoor high-dust environment at drilling sites with IP54 protection rating, possessing anti-vibration and -20℃ cold resistance capabilities;
Processing efficiency no less than 5 tons/day with industry-leading technology to reduce on-site processing costs.
Solutions：
Formed special R&D team adopting "thermal drying + solid-liquid separation" innovative process (industry-leading) with optimized thermal cycle system improving energy efficiency;
Leveraged metal processing experience to fabricate equipment housing using weather-resistant steel with sealed chamber design enhancing outdoor adaptability;
Followed ISO9001 system conducting 200-hour continuous operation tests on core components (thermal decomposer, separation unit) to verify performance reliability.
Implementation Results:
Equipment achieved processing efficiency of 6 tons/day with solid waste moisture content reduced to 12%, helping customers achieve environmental compliance;
Operated continuously for 3 months without failure at northwest drilling site with -18℃ temperature, earning high recognition for harsh condition adaptability;
Single-well oil sludge processing cost reduced by 25%, leading to subsequent 3-unit follow-up orders and establishing position as core environmental equipment supplier.
