摘要： A gas operated, submersible pumping system, is disclosed as being capable of recovering well fluids below ground surface from a natural gas production well and is adapted to be coupled to flexible continuous metal conveyance conduits. The system includes a housing constructed of a corrosion resistant material; gas inlet and output ports for accommodating respectively higher and lower pressures; well fluids inlet and outlet ports; an internal gas logic switching valve to control pumping action; and a pneumatic mechanical amplifier piston, which isolates gas from liquids, and transfers lower pressure gas into higher pressure liquid discharge pressure, wherein the submersible pumping system is operable between a refill and discharge mode so as to recycle inlet well gas back into the production well without substantially reconstituting the well gas.
摘要翻译：公开了一种气体操作的潜水泵送系统，其能够从天然气生产井中回收地下表面以下的井液，并适于与柔性连续的金属输送管连接。该系统包括由耐腐蚀材料构成的壳体; 气体入口和出口用于容纳分别更高和更低的压力; 井流体入口和出口; 内部气体逻辑切换阀，用于控制泵送动作; 以及气体机械放大器活塞，其将气体与液体隔离，并将较低压气体转移到更高压力的液体排出压力中，其中潜水泵送系统可在再填充和排出模式之间操作，以将进口井气体再循环回生产井而没有大量重构井气。

摘要： A soap film type gas flowmeter has an inverted U-shaped gas flow tube adjustably mounted in a sensor assembly. The inverted attitude of the gas flow tube prevents backflow of the soap film solution down to the sensor assembly and prevents diffusion of a heavier gas than the gas whose flow is being measured into the gas flow tube, thereby eliminating diffusion of a lighter gas through the soap film during measurement. The adjustable mounting of the gas flow tube enables optimum operation of the flowmeter for widely ranging gas flow rates. The glass flow tube is made from mandrel drawn glass to ensure high accuracy, which allows interchangeability from flowmeter to flowmeter with no change in accuracy.
摘要翻译：皂膜型气体流量计具有可调节地安装在传感器组件中的倒U形气流管。气体流管的倒置姿态可防止皂膜溶液向下传递到传感器组件，并且防止比流动被测量的气体更重的气体扩散到气体流管中，从而消除较轻气体通过测量过程中的皂膜。气体流量管的可调安装使流量计能够在广泛范围的气体流量下实现最佳的操作。玻璃流管由心轴拉制玻璃制成，以确保高精度，这允许流量计与流量计的互换性，精度没有变化。
