Liquid Nitrogen Freeze Sealing Unit.

  • 70MPa/105MPa.
  • Injection speed:0-30L/min.(Adjustable)
  • This equipment is a core accessory for pressure operation, specifically developed for oilfield drilling, well servicing, fracturing, and wellbore maintenance operations. It uses low-temperature freezing technology to achieve rapid and temporary plugging of wellbore media. It can form a high-strength and well-sealed temporary plugging barrier without depressurization or production suspension, effectively isolating the operation layer and avoiding wellbore backflow and medium leakage issues, significantly enhancing the safety and efficiency of downhole operations.
  • The equipment integrates a low-temperature refrigeration system, precise injection, pressure monitoring and other integrated systems. It features high refrigeration efficiency, rapid temporary plugging formation, and adjustable plugging strength as per requirements. It is suitable for different well depths, pressure grades and wellbore medium conditions. The temporary plugging range is precisely controllable, and there is no residue after construction, which is easy to unblock. It does not damage the wellbore tubing and formation, and is compatible with various oil and gas well operation requirements.
  • The overall modular design is compact and lightweight, suitable for rapid transportation and installation at field well sites. Core components are made of high-quality materials that are resistant to low temperatures, high pressure, and corrosion, capable of withstanding harsh oilfield operating conditions. It is equipped with multiple safety protection and intelligent monitoring devices to monitor refrigeration, pressure, and injection agent parameters in real time, ensuring comprehensive safety during operations. It provides an efficient, environmentally friendly, and reliable temporary plugging solution for oilfield snubbing operations and wellbore renovations.
