摘要
文中较全面地介绍了排水采气工艺中的泡沫排水、气举排水、机抽排水等人工举升工艺，在可行性论证和方案设计中的经济评价方法，提出了计算公式和判别式。分别对增产成本计算、日产气量、注采比、泡排工艺预计增产气量、效果计算、最短（检泵、检阀）作业同期计算、投资回收期计算和老井工艺井是否有价值继续运行的公式和判别式进行分析，对这些算式和判别式的实际运用作了论证并写出了算例。
Artificial lift methods for dewatering gas production, including foam dewatering, gas lift andpumping etc., are introduced herein. The paper presents how to make economic evaluation of dewatering gas production when doing feasibility study and program design, gives related computing formulae and discriminants.And all kinds of different formulae and discriminants are analysed and demonstrated by examples.
