摘　　要：总结了辽河油田东部凹陷的测井特征,分析了其储层的物性特征及物性控制因素,结合前人的工作,给出了计算孔隙度和渗透率的方法,计算结果与实验结果对比比较符合。利用F-S方法并结合地区性质得到的经验公式及利用达西定律推导得出的理论公式,编写了煤层气测井解释程序,并对一些井进行了处理,得到了煤层处理剖面图,从剖面图上可看出,煤层的孔隙度和渗透率都很低,其处理的孔隙度结果与测试结果对比基本吻合;在欧15井煤层井段进行了单相注入压降测试,从测试结果看所计算的渗透率比较准确。In the paper,the logging features of the eastern depression in Liaohe oilfield are summarized,and the physical property characteristics of the reservoirs and controlling factors are analyzed.Proosity and permeability calculation method is given out which corresponds with the experimental result.The well logging interpretation program for coalbed gas is composed with two formulae.One is experimental formula from F-S method combined with the area properties,the other is theoretical formula derived from Darcy law.The program is used to process some wells to get the profile.It can be seen from the profile that proosity and permeability of coal beds are very low.The process coincides with testing.Single-phase injection pressure drop test was carraried out in the coalbed interval of Well 15.The result shows that the calculated permeability is more accurate.
