Abstract：Qinshui Basin,rich in coalbed methane resources,has been the focus of coal-bed gas in China and higher investment in science and technology,one of the areas with a larger research effort.Shizhuang North X2 well in Qinshui Basin,coalbed methane yield is relatively low due to its exploration wells are polluted by fracturing effect.In view of the problems arising from the exploitation of coalbed gas,through a large number of scientific reasoning,we creatively propose referencing oil industry production technology mean as yield-increasing technique of coal-bed methane production.Results show that coal-bed gas production shows a significant rise from 200 m3/d to 2 400 m3/d after using hydraulic jet radial direction drilling technology in X2 well and reaching the desired effect.
