China is rich in coal-bed methane (CMB) resources, and has a vast exploitable volume, but the surface gathering system is not perfect. In order to solve the problems of high degree of difficulty in surface gathering system design and lower economic efficiency caused by the characteristics of CBM gas field geographically remote, more wells, large water production in single well and gas containing pulverized coal etc, we studied the select method of the piping material of CBM, process and the treatment technologies of produced water in F block of the southern Qinshui Basin. Finally, the first phase production can reach 6 × 108m3/a and the central processing plant size is 10 × 108m3/a in the F block. The application of this study not only reduced the capital investment but also met the requirement of good environmental protection. This gathering process design can be applied to other development and construction of CBM gas fields.
