| 摘 要： | 经过一系列试验和误差分析之后，制定出了用于实验室分析的煤层岩心样品切割、处理、备制的选择方法；寻求出全直径煤层岩样测定相对渗透率的非稳定方法，并取得满意的结果；开发出一种新型的不损坏样品的简单的实验室技术，估算出与煤层割理网络相关的孔隙度和残余水饱和度。文中以桑珠安（SaJnuan）和华里尔（Warrior）煤田的煤岩样品试验结果为例进行了叙述。实验室所测得的煤层相对渗透率曲线、孔隙度和残余水饱和度对于数值模拟和其它煤层气工程研究都具有重要的价值。

| Abstract: | After a series of trials and errors,an acceptable procedure has been formulated for cutting, handling, preparing and selecting coalbed core samples for laboratory tests. The unsteady-state method for relative permeability measurement has been found to provide satisfactory results when applied to whole-diameter core samples of coal. Furthermore,a novel nondestructive and simple laboratory technique has been developed to estimate the porosity and irreducible water saturation associated with the coal cleat network.In this paper,examples are presented using results obtained with coal core samples from the San Juan and Warrior basins. The relative permeability curves,porosity,and irreducible water saturation of coal cleats measured in laboratory have been proven valuable in numerical simulation and other engineering studies of coalbed methane recovery. |
