Challenge
Located at an elevation exceeding 2,800 meters, the YZ2-5-3X well in Qinghai Oilfield faces extreme operational conditions—low ambient temperatures, high wax content crude oil, and frequent paraffin deposition. Prior to intervention, the well required chemical hot washing every 7–10 days, resulting in high operational costs, environmental concerns, and recurring unplanned shutdowns due to pipeline blockages.
Solution
In 2023, JingTao Energy deployed its Physical Active Variable-Frequency Electromagnetic Wax Prevention and Viscosity Reduction System at YZ2-5-3X. This intelligent system leverages a full-sweep-frequency electromagnetic field (10–500 Hz, adaptive control algorithms, and a three-stage staged magnetic layout to simultaneously address wax deposition, viscosity, scaling, and corrosion—without chemicals or thermal input.
Key technical features implemented:
- Real-time temperature and flow feedback for dynamic frequency adjustment
- Effective treatment range >1,500 meters along the production string
- Integrated HMI/PLC with remote monitoring and auto-restart capability
- IP68-rated, explosion-proof (Ex d IIB T4) design for high-altitude reliability
Results
Within six months of installation, the system delivered transformative outcomes:
- 80% reduction in chemical usage, aligning with China’s “Dual Carbon” and green oilfield initiatives
- Zero wax-related blockages for over 180 consecutive days
- 25% decrease in unplanned downtime, enhancing production continuity
- Crude oil viscosity reduced by up to 70% (under <30% water cut conditions)
- Corrosion rate on tubing walls reduced by over 40%, extending asset life
Strategic Impact
The success at YZ2-5-3X demonstrates JingTao Energy’s system as a scalable, eco-friendly alternative to conventional wax management—particularly in harsh, remote environments. The well now operates with minimal human intervention, fully integrated into the oilfield’s digital monitoring platform, paving the way for broader deployment across Qinghai’s high-wax, high-altitude blocks.
