通井机是一种用于起下油管、钻杆、抽油杆,或抽汲、打捞、通井等作业,以专业底盘为基础的专业石油钻采设备,对于石油开采有着非常重要的作用。本文介绍一种改良液压系统的轮式通井机,具有移动方便、操作灵活、修井速度快等一系列优点,同时在保证运行需求的基础上简化了系统结构,降低了通井机成本。本文分析其在某油田的应用,进一步证明其实用性和先进性,建议在各个油田广泛采用。 Drilling machine is a kind of professional oil drilling equipment which is used for lifting oil pipe, drill pipe, sucker rod, or pumping, salvage, well drilling and so on. It has a very important role for petroleum exploitation . This paper introduces a series of wheel well machines with improved hydraulic system, which are easy to move, flexible in operation and quick in workover. At the same time, the system structure is simplified and the cost of well machine is reduced. This paper analyzes its application in an oilfield, to further prove its practicality and advanced, it is recommended in various fields widely used.
