【摘要】 油田大量的原油挥发气一直都被直接排空处理 ,既浪费了大量的能源 ,又造成了严重的环境污染。依靠压力较高的天然气采用喷射技术对原油挥发气进行回收 ,不需要其他的能源 ,又具有很高的安全性。为此 ,在大量实验的基础上 ,专门研究了匹配式多级喷射技术。试验结果表明 ,该技术是切实可行的 ,具有在工程实际中推广使用的价值更多还原

【Abstract】 The crude oil gas in our country is discharged into air directly, which not only wastes the energy, but also pollutes the atmosphere. The recovery of light hydrocarbon with the ejectors by pressure of natural gas is very safe, and it doesn’t need other kinds of energy. This paper goes deep into the study for the matching of series ejectors, and the testing in oil field has demonstrated that this technology can be used in practice.更多还原
