Abstract: According to the single we ype and completion technology.insuficient matched domestic: rlling equipment and other problems faced to the coalbed methane surace ground development in thecoal mine area,a nev acurate buted calbed methane development mode with a butted point and two side branches was studied and practices a matched ill hyarauli truck mouned driling rig was researched and developed and the completed set drlling equipment system was inegrated.Tthe accurate buted drling techniue was studied and developed,a seres well completion technology was summarized and formed and the first igh production renoteaccurate buted wel n Chinacoal mine area was construced in Jincheng Mining Area.The accurate butted dillig technology and equipment was promoted and appld toseveral coalted methane exploration and development projects. One after another,10 diferent type accurate well uted groups were established,16 horizontal buted wels were constructed a max buted distance was 1 065 m,the max verical ratio was 3.7 and the max dailygasproduction was 32800 n-3( N0.15 seam in Jincheng lMining Area The technology and ecquipment could provide a technical and equipment suppor torealize acoabed methane high eficient development on the surace.
