///The Hancheng is the city of Shanxi Province, it is one of Shanxi Province main coal production bases, and there is a rich coal bed gas. The gas bearing degree of saturation is good and is the ideal target area. Sneaks in the technical mining CBM using the direction detection to have the production cost to be low, the coal bed output is high merit. This paper elaborated take Hancheng sub-area WL2-015 to 1 well as the example the coal bed was made the directional well drilling craft, and summarized the coal bed to be made the directional drilling related construction experience.
