Abstract:Through reviewing the course of coal-bed methane exploration and development for more than ten years in China and in consideration of domestic drilling technical level and the petrophysical analysis data of coal reservoir in Qinshui coalbed methane field,it is pointed out that it is an important means of advaning to-ward industrialization of the coalbed methane exploration to apply multi-branch horizontal drilling techniques to exploiting Qinshui coalbed methane field.The coal seam features of Qinshui field,the feasibility of applying the multi-branch horizontal drilling techniques to exploiting Qinshui coalbed methane field,its design plan and the key techniques and special downhole tools of the drilling techniques are introduced and the technical implementation program of coalbed methane development under the conditions of domestic available techniques and equipment is proposed in the paper.
Keywords:Coal bed  Physical property  Drilling  Technique  Multi-branch horizontal well  Design  Special downhole tool
