AbstractThe Qinshui basin is the most successful area for coalbed methane (CBM) development in China. Since 2008, 45 multibranched horizontal wells (MBHWs) have been put into production in the Fanzhuang block, of which 10 wells have an average daily gas rate (DGR) of >10 000 m3/d. Well 4‐5 with the total gas production of 1.054 × 108 m3achieved the China's highestDGRof 63 744 m3/d. Compared with vertical wells,MBHWis an effective way to developCBMin low permeability reservoirs in China. However, there are still 23 wells have an averageDGRof <3000 m3/d, of which 18 wells are below 1000 m3/d. The results show that shallow depth (<600 m), high gas content (>16 m3/t) and saturation (>80%), long coal seam interval (>3000 m), reasonable branch spread, and stable wellbore are the basis for achieving high production. The encountered faults connected to the aquifer will cause a high water production and an extremely low gas rate (<1000 m3/d). In the inclined coal seam, the up‐dipMBHWis more favorable for the formation water drainage and the pressure drop funnel expansion than the down‐dipMBHW, and the horizontal well should be drilled perpendicular to the high‐permeability direction to achieve a higher recovery ratio.MBHWis more sensitivity to drainage rate due to the coal fine migration in the horizontal segments, and the high pressure drop rate will lead to high frequency of stunk pump and eventually affect the gas production. Currently, the biggest challenge forCBMdevelopment withMBHWis wellbore stability. 57% of inefficient wells are caused by wellbore collapse during drilling and production processes. Here, a new type of “Roof Drilling‐Tree Shaped” horizontal well structure was presented in this work. The first “Roof Drilling‐Tree Shaped” horizontal well with a total length of 12 288 m and a coal seam interval of 9408 m was successfully applied without drilling accidents.
