| Abstract: | Taking Tunlan mine TL-U-18301 coalbed methane well as the research object,the construction technology of U-shaped well is studied,and the lower group of coal and coalbed methane is drained through the pressure relief zone through reasonable drilling arrangement to solve the gas problems in the working face.The article introduces the drilling tool assembly and the L well and the vertical well respectively,and explains the connection technology of the two kinds wells,and gives some understandings for the construction.The results show that the project completed in 44 days with the L well being 1142.88 m deep and the vertical well 481 m deep.The two kinds wells are connected efficiently and accurately,providing a new idea for the treatment of gas problem. |
