    • A production plunger that automatically reciprocates in a production string of a well to remove formation fluid from the well. The production plunger makes a sealing contact with the production string and includes a passage through which all formation fluid is caused to flow through. The passage includes a valve that operates automatically in response to pressure within the production string to open and close the passage to allow and stop formation fluid from flowing in the passage. The plunger includes a locking device to ensure the plunger does not short cycle and a fail safe mechanism ensuring the valve closes in case of plunger failure, or upon a minimal build up of pressure by shutting in the well. Further, the entire valve is enclosed in the plunger preventing damage to valve elements from impacting downhole equipment, and the plunger includes fluid ports positioned so as not to easily capture well solids.
    • 生产柱塞,其在井的生产管柱中自动往复运动,以从井中除去地层流体。 生产柱塞与生产线密封接触,并且包括使所有地层流体通过的通道。 通道包括响应于生产线内的压力而自动操作以打开和关闭通道以允许和阻止地层流体在通道中流动的阀。 柱塞包括锁定装置以确保柱塞不会有短暂的循环,并且在柱塞故障的情况下确保阀关闭的故障安全机构,或者通过在井中关闭来最小化压力。 此外,整个阀封闭在柱塞中,防止阀元件的损坏冲击井下设备,并且柱塞包括定位成不容易捕获井固体的流体端口。

    • In a multi-service platform system (300), a method of skew adjustment can include providing an initiator VME module (302) coupled to a responder VME module (304) over a parallel multi-drop bus network (306). The initiator VME module communicates a calibration cycle (316) to the responder VME module during a calibration phase (208), where the calibration cycle includes a reference signal (322) and a training data signal (324) having a preset relationship (321), and where the calibration cycle is communicated using a source synchronous protocol (107). The responder VME module calculates a deviation (350) from the preset relationship of the reference signal and the training data signal, where the deviation comprises a delay time (325). The initiator VME module communicates a data signal (418) to the responder VME module during a data phase (210), where the data signal includes the reference signal and an actual data signal (426). The responder VME module delays one of the reference signal and the actual data signal by the delay time.
    • 在多业务平台系统(300)中,偏差调整的方法可以包括通过并行多点总线网络(306)提供耦合到响应者VME模块(304)的启动器VME模块(302)。 启动器VME模块在校准阶段(208)期间将校准周期(316)传送到响应者VME模块,其中校准周期包括参考信号(322)和具有预设关系的训练数据信号(324)(321) ,并且使用源同步协议(107)传送校准周期。 响应者VME模块从参考信号和训练数据信号的预设关系计算偏差(350),其中偏差包括延迟时间(325)。 启动器VME模块在数据相位(210)期间将数据信号(418)传送到响应者VME模块,其中数据信号包括参考信号和实际数据信号(426)。 响应者VME模块延迟参考信号和实际数据信号之一延迟时间。

    • A plunger of improved construction for reciprocating in a production string of a gas or oil well to remove fluid from the well. The plunger includes a sleeve having a through passage extending longitudinally from a first end to a second end, the second end forming a seat, a sealing means carried by the sleeve for engaging the inner surface of the production string, a detachable valve member releasably received by the seat to seal the through passage, and a catch positioned to releasably couple the detachable valve member to the sleeve within the seat. The catch retaining the detachable valve member until the detachable valve member is impacted at the surface of the well by a trip rod. The improved construction provides for the use of a heavier or more dense detachable valve member and a lighter or less dense sleeve than previously used in prior plungers, which results in a plunger having an increased efficiency and a greater cycle frequency.
    • 一种改进的结构的柱塞,用于在气井或油井的生产线中往复运动以从井中移除流体。 柱塞包括一个套筒,该套筒具有从第一端至第二端纵向延伸的通道,第二端形成座,由套筒承载的用于接合生产线的内表面的密封装置,可释放地接收的可拆卸阀构件 通过座椅密封通过通道,以及定位成将可拆卸阀构件可释放地联接到座椅内的套筒的卡扣。 保持可拆卸阀构件的止动件,直到可拆卸的阀构件通过脱扣杆在井的表面处冲击。 改进的结构提供使用比先前在现有柱塞中使用的更重或更致密的可拆卸阀构件和较轻或较不致密的套筒,这导致柱塞具有增加的效率和更大的循环频率。
