摘　　要：多分支水平井技术是一项具有广阔发展前景的新兴开发技术,具有不同的几何结构和相应的应用条件。与常规直井相比,在开发低渗透储层煤层气资源时,多分支井具有单井产量高、采出程度高和经济效益高的优势。本文论述了多分支水平井在煤层气开发中的控制因素和增产机理,并对其在沁水煤田模拟应用作了分析。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.
