在我国现代化建设工作的逐步落实下,天然气生产企业对高压低渗气井的依赖性也愈来愈高了,这是天然气生产企业顺应时代潮流,跟上社会进程的体现,也是对我国现今现代化建设工作的一种肯定。就我国目前现状来说,高压低渗气井已经成为了天然气生产企业发展历程中的一个关键点了,高压低渗气井的运行更直接主导了天然气生产过程的整体运作,对天然气生产过程中每一个阶段每一个环节都有着极为深远的影响。本文将从气井下高压低渗气井产能预测工作的角度出发,对这一项工作在天然气生产过程中的重要性进行深入讨论。 相似文献

A pump suitable for use with gas electrodes, in which recirculation of the gas is necessary, is described. The system to which the cell with the gas electrode and the pump are connected does not change its volume when the pump is in operation. The pump works as follows: an embolus, consisting of a Tefloncoated magnetic stirring bar, placed inside a glass tube having an internal diameter slightly larger than the diameter of the bar, is moved from the outside with a permanent magnet, which in turn is moved horizontally along the tube by means of a mechanical assembly driven by an electric motor. The motion of the embolus is accompanied by the closing and opening of glass valves which allow the gas to circulate in the desired direction. The pump, used in conjunction with a vacuum line, operates from pressures as low as 60 Torr to above atmospheric pressure. The operation of the pump is unaffected by organic gases and most inorganic gases. 相似文献

气辅成型中气道设计对气体穿透的影响 总被引:1,自引:0,他引:1
气道的设计是气体辅助注射成型中的一个重要因素,不同的气道对气体穿透会产生不同的效果。利用模塑软件Moldflow分析了不同尺寸的矩形截面气道的气体穿透情况。结果表明,当量直径太小的气道,气体容易渗透到薄壁区域;而当量直径太大,气体穿透长度会减小。最后,还给出了一些气道设计的基本原则。 相似文献

Membrane gas absorption (MGA) is an efficient and flexible way to carry out gas-liquid (G-L) contacting operations with hollow fibre membranes. The main advantages of membrane gas absorption over conventional G-L contactors is the compactness and low weight of the installation, the standard modular construction elements and the flexible operation. Gas and liquid flow can be controlled independently in the MGA process, which makes operation over a wide range of liquid and gas flow rates possible. In a MGA installation no entrainment, flooding, channelling or foaming occurs. Rob Klaassen and Albert E Jansen, TNO Environment, Energy and Process Innovation, discuss the principle of this technology, the benefits of newly developed membrane modules and their potential applications. 相似文献
