美国Nojak Pumping Solutions公司成功开发了一种新型抽油系统。该系统利用气体压力,通过直接配置在套管内的一系列密封腔室举升井液,包括2个主要部分:压力驱动腔和地面控制系统。它有一系列间隔76m连成一体的,悬挂在油管总成上的压力驱动腔。其控制系统包括1台压缩机和1台可将
Nojak Pumping Solutions USA successfully developed a new pumping system. The system utilizes gas pressure to lift the well fluid through a series of hermetically sealed chambers disposed directly inside the casing, including two main sections: a pressure-driven cavity and a ground control system. It has a series of pressure-driven chambers suspended in a tubing assembly at 76m intervals. The control system includes a compressor and a can be
