The associated‑gas oxygen burner is specially developed for oilfield wellhead associated‑gas recovery and utilization. It directly burns oilfield produced associated gas as fuel to eliminate waste and air pollution caused by associated‑gas flaring, realizing waste‑gas resource utilization and acting as core equipment for oilfield circular economy and carbon‑reduction projects. Matched with Crude Oil Heater and Crude Oil Heat Exchanger, it converts recovered associated gas into stable thermal energy to supply sufficient heat for crude oil heating, viscosity reduction and anti‑solidification. With excellent cross‑system adaptability, it cooperates with Single Well Oil Storage Tank to complete the full wellhead oil‑storage and heating process, and connects Solid‑state Energy Storage Heating Equipment, Multi‑energy Coupled Crude Oil Heating Equipment and New Energy Zero‑carbon Heating Equipment to realize complementary operation between associated‑gas combustion heating and new‑energy stor…
