气举阀气举排液技术研究

气举排液是一种常用的气井排液采气工艺,不但适用于低产气井的辅助排液采气,而且还适用于各种类型积液停产气井的诱喷排液复产。介绍了气举阀的工作原理及类型,建立了气举阀特性数学模型,并对其检测、调试技术及排液管柱结构进行了研究。气举阀排液技术因其安全、高效而在油田得到推广应用,该技术具有良好的经济效益和社会效益。

Study on Technique of Gas Lift Flowing Back Via GLV

In the process of development and production of oil and gas,with regard to non-flowing well,through the methods such as swabbing,pump drainage,gas lift and so on extruding the fluid out of borehole,this could reduce the fluid column pressure,make formation fluid flowing toward borehole and lift up to ground.It is widely used of GLV because of its safety and high efficiency in oilfield.Gas lift flowing back is a kind of normal gas production technology,which adapts both to auxiliary unloading and gas product...
