| Abstract: | The Multiple Laterals Horizontal Well (MLHW) is a newly developed technology with a bright future. It has some different geometric structures and corresponding application conditions. Compared with traditional vertical wells, when exploring the CBM in low permeability reservoir, the MLHW has the advantages such as high production per well, high degree of reserve recovery and great economic benefits. In this paper, the control factors and production enhancing mechanism are analyzed of the MLHW in developing CBM; the simulated application of the MLHW in Qinshui coal field is also discussed. |
| Keywords: | Coalbed methane multiple laterals well development control factors production enhancing mechanism |
