Abstract: There are few effective means to increase and stabilize production in gas wells of low pressure, low yield, and low amount of water in domestic gas fields. To solve the problem, Jianghan Machinery Research Institute develops China's first skid-mounted capillary tube unit for water drainage and gas production was manufactured with independent intellectual property right. Great breakthroughs have been made in some key techniques, and full scale test of 23 wells has been accomplished successfully. Field test shows that the unit performs well in killing the well and achieves good process effect. It provides important technical equipment for water drainage and gas production as well as stimulation, filling domestic blank and catching up with advanced world levels. It has broad prospect for application.

Key words: capillary tube unit, water drainage and gas production
