    • A programmable controller monitors and operates a variety of analogue and digital devices. An on-cycle of the well is initiated based on a pressure differential measured between a casing pressure and a sales line pressure. When a predetermined ON pressure differential is observed, the controller initiates the on-cycle and open a motor valve to permit fluid and gas accumulated in the tubing to be urged out of the well. Thereafter, the controller initiates a mandatory flow period and maintains the motor valve open for a period of time. During sales time, the controller monitors the gas flow through an orifice disposed in the sales line. When the measure pressure differential across the orifice is less than or equal to a predetermined OFF pressure differential, the controller initates the off cycle. The off cycle starts with a mandatory shut-in period to allow the plunger to fall back into the well.
    • 可编程控制器监控和操作各种模拟和数字设备。 基于在套管压力和销售线路压力之间测量的压差来启动井的开环。 当观察到预定的ON压差时,控制器启动开启循环并打开电动机阀,以允许积聚在管道中的流体和气体被推出井。 此后,控制器启动一个强制性的流程周期并保持马达阀打开一段时间。 在销售期间,控制器监视通过设在销售线上的孔的气体流量。 当孔口上的测量压力差小于或等于预定的关闭压力差时,控制器启动关闭循环。 关闭循环从强制关闭周期开始,以使柱塞回到井中。

    • A programmable controller for operating an artificial lift well is provided to monitor and operate a variety of analog and digital devices. An on-cycle of the well is initiated based on a pressure differential measured between a casing pressure and a sales line pressure. When a predetermined ON pressure differential is observed, the controller initiates the on-cycle and open a motor valve to permit fluid and gas accumulated in the tubing to eurged out of the well. Thereafter, the controller initiates a mandatory flow period and maintains the motor valve open for a period of time. The valve remains open as the system transitions into the sales time period. During sales time, the controller monitors the gas flow through an orifice disposed in the sales line. A differential pressure transducer is used to measure a pressure differential across the orifice. When the measure pressure differential is less than or equal to a predetermined OFF pressure differential, the controller initiates the off cycle. The off cycle starts with a mandatory shut-in period to a low the plunger to fall back into the well. Thereafter, the well remains in the off-cycle until the controller receives a signal that the ON pressure differential has developed. In another aspect, the controller may adjust the operating parameters of the well based on the completion of the cycle.
