Abstract: According to the production data of 83 coalbed methane(CBM) wells in Block 3 on the eastern margin of Ordos Basin, the effects from geological conditions, engineering technology, draining technology and other factors on CBM well productivity were systematically analyzed, and on this basis, the relevant development strategies were put forward. The results show that the main geological factors influencing CBM productivity include coal bed thickness, underground water fluid potential, gas content, permeability and critical reservoir ratio. The major engineering technology factors affecting CBM productivity include well spacing size, total fracturing liquid volume and sand adding amount. The lowering speeds of bottom hole pressure and working fluid level as well as casing pressure directly influence CBM productivity. On this basis, gray relative analysis method is used to obtain the degree order of CBM productivity influencing factors in the study area. Meanwhile, from the four aspects including favorable zone optimization, well pattern deployment, fracturing design and producing measures, the development strategies suitable for CBM geological characteristics in the study area were put forward as follows. In the aspect of favorable zone optimization, the evaluation indicators for favorable CBM development zone were established to divide the development unit into Ⅰ-Ⅳ units types. In the aspect of well pattern deployment, the well spacing sizes of Type I and Type Ⅱ units should be controlled within 335-370 m, and those of Type Ⅲ and Type IV units should be limited in 370-400 m. In the aspect of fracturing design, the fracturing liquid volumes of Type I and Type Ⅱ units should be controlled in 800-1 200 m³, and the sand adding amount should be limited within 35-60 m³. Due to poorer coalbed geological conditions of Type Ⅲ and Type IV units, different fracturing measures were proposed for different geological conditions. In the aspect of producing measures, the CBM producing process in the study area was divided into five stages, and the specific CBM-producing controlling methods are put forward aiming at different producing stages.
