液氮泵设备在煤层气开采方面的应用

Application of liquid nitrogen pump in coal seam gas mining

液氮泵车自1994年从国外引进后,并应用在吐哈油田,先后开发了氮气气举、氮气置换、混气压裂、混气酸化、氮气正负压射孔、氮气垫测试等应用技术,成功解决了油田生产中的一些特殊难题。

The liquid nitrogen pump was introduced from abroad in 1994.And used in Tuha oilfield,The application technologies of nitrogen gas lift,nitrogen replacement,mixed gas fracturing,mixed gas acidification,nitrogen positive and negative pressure perforation,nitrogen air cushion test have been developed successively.Some special problems in oil field production have been successfully solved.
