该文介绍了一种新型煤层气录井方法,通过计算岩屑厚度、煤的重量和体积、井筒体积等计算煤层气含量,实时评价单个或多个煤层。采用该计算方法可以替代成本高且耗时的对整块岩心进行密封罐解吸分析方法,是煤层气录井技术的一大突破。该方法通过现场实际应用,效果较好,具有较好的发展前景。 This paper introduces a new method of coalbed methane logging, which calculates the CBM content by calculating the thickness of cuttings, the weight and volume of coal, the volume of wellbore and so on, so as to evaluate one or more coal seams in real time. The calculation method can replace the costly and time-consuming analysis method of sealed cans desorption of the whole core, which is a breakthrough of the CBM logging technology. The method through the field of practical application, the effect is better, with good prospects for development.
