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。
The logging features in the eastern sag of Liaohe Oilfield are summarized, and the physical properties and physical control factors of the reservoir are analyzed. Based on the previous work, the methods of calculating porosity and permeability are given. The calculated results are in good agreement with the experimental results . Using the FS method combined with the empirical formula obtained from the nature of the area and the theoretical formula derived from Darcy’s law, a coalbed methane well logging interpretation program was prepared and some wells were treated. The coal seam treatment profile was obtained. From the cross-sectional view It can be seen that the porosity and permeability of the coal seam are very low, and the porosity results of the treatment are in good agreement with those of the test results. The single-phase injection pressure drop test is carried out in the well section of Euro-15 well. From the test results, Calculated permeability is more accurate.
