The oilfield-specific high-pressure liquid nitrogen (LN₂) skid is a custom-engineered modular core equipment tailored for oil and gas extraction scenarios. Seamlessly integrating key components including high-pressure LN₂ plunger pumps, direct-fired vaporizers, power systems, hydraulic systems, and intelligent control systems, it is fully compatible with ultra-low temperature LN₂ medium at -196℃. This skid efficiently meets the high-pressure nitrogen demands for critical operations such as oilfield fracturing, gas lift, and urban pipeline purging, boasting core advantages of enhanced mobility, rapid deployment, and reliable safety performance. It delivers stable, robust support for improving the quality and efficiency of oil and gas extraction.
