For a higher yield, the multibranch well bore should be perpendicular to the direction of maximum principal permeability, b. for a given coalbed methane reservoir, there is an optimal interspace, by which a bigger control area and the interaction among the branches can be obtained, and c. with the extension of the branch, gas yield becomes obviously higher, while the branch length should be an appropriate value on account of the influence of coal bed boundary and wellbore pressure drop. The research results have guiding significance for well pattern optimization and efficient development of coalbed methane gas.

结果发现：为了获得较高的产能，多分支井的井筒应垂直于最大主渗透率方向；对于给定的煤层气藏，存在一个最优的分支间距，既能保证较大的控制面积，又能保证分支间的互相影响；随着分支长度的增高，产气量也显著增大，但是考虑到煤层边界和井筒压降的影响，分支长度也应该有一个比较合理的值。
