摘要：

以研究煤储层物性非均质性，识别煤层气藏类型为切入点，分析产能与煤层气藏类型之间的关系，发现高产井（>3000 m3/d）主要分布在富集高渗煤层气藏内，中产井（1500～3000 m3/d）主要分布在高饱和度低渗透煤层气藏内，而高渗透率低饱和度煤层气藏和低渗透率中低饱和度煤层气藏这2类气藏，受渗透率和含气量制约，其煤层气井产能一般偏低。

Abstract:

According to physical heterogeneity of coal seam as gas reservoir and type of coalbed gas reservoir, we discuss the relationship between types of coalbed gas reservoir and gas productivity, and find out that the CBM well with high gas productivity (>3 000 m3/d) is distributed in the high permeability coalbed methane reservoir; the well with middle gas productivity (1 500~3 000 m3/d) is in the high saturation and low permeability coalbed methane reservoir. But two types of coalbed reservoirs with high permeability and low saturation, and low permeability and high saturation, respectively, are restricted by permeability and gas content, with low gas productivity.

Key words: Jincheng CBM zone, CBM well productivity, CBM reservoir types, Geologically controlling factors.
