为大幅降低高油气比油井的天然气处理和再注入成本，防止并下设备受气体影响和过量产气，美国研制成功一种天然气井下处理和再注入压缩机（SPARC）。这种压缩机利用天然气通过油嘴后的剩余能量，靠涡轮膨胀机供能，处理、压缩和再注入高油气比油井的30％－60％的产出气。SPARC To dramatically reduce the cost of natural gas processing and reinjection in high-oil-gas ratio wells and to prevent gas undermined and excessive gas generation in the subsurface facilities, the United States developed a natural gas downhole process and reinjection compressor (SPARC). The compressor uses the residual energy of the natural gas passing through the nozzle to power the turbo-expander to process, compress, and re-inject 30% to 60% of the high-gas-to-oil production gas.
