目前,油价不断攀升,有杆泵采油的动力成本也在连续升高,为了降低有杆泵采油成本,美国Deluge公司开发成功一种天然能量发动机,并据此研发成功了一种靠水运转的有杆泵抽油系统。通常在足够的压力下储存的CO2可保持液态,温度升高时其体积可膨胀50%,而水只能膨胀2%。因此,将液态的C At present, the rising oil prices, rod pump oil production costs are also continuously rising, in order to reduce rod pump oil production costs, the United States Deluge company developed a natural energy engine, and successfully developed a water-based operation Rod pump pumping system. CO2, which is usually stored under sufficient pressure, remains liquid, expands its volume by 50% at elevated temperatures, and water expands by only 2%. Therefore, the liquid C
