Abstract: Based on the study of CBM development technological data, this article makes briefings about the present conditions of CBM development technology, such as drilling, fracturing, extraction of gas and EOR. Focusing on the technological characteristics and application results, the article also analyzes the application potential and development orientation of CBM development technology. In the light of China’s CBM geological conditions, it proposes to introduce and develop multi-lateral horizontal well technology and coil tubing fracturing technology and further perfect the supporting technology, such asdrillingfluid, fracturingfluidandcompletion fluid.

Key words: CBM, development, drilling, fracturing, drainage and gas production, recovery factor, CO2-ECBM, development trend
