North China's independent research and development of bio-based nanobubble discharge agent has significant application effects

Recently, the bio-based nanobubble discharging agent independently developed by the Engineering Institute of North China Oil and Gas Branch was applied for the first time in low-pressure and low-yield wells in Daniudi Gas Field.

Aiming at the problem that the foaming, stabilizing and liquid carrying performance of the existing foaming agent in Daniudi gas field in low-pressure and low-yield gas wells causes poor foaming effect, the North China Institute of Engineering independently developed a foam with lower water content and stronger foam stabilization ability.

In order to do a good job in the application of new materials and new products, technicians do detailed preliminary work, strengthen dynamic analysis based on static data of gas wells, carry out gas well inspections, and verify the pressure, production, and fluid accumulation of low-yield wells, etc.

At present, the implementation of bio-based nanobubble discharge agent drainage gas production well measures has an effective rate of 100%, and the single well oil jacket pressure difference has dropped by 0.
