摘　　要：补偿中子测井在煤层气评价中应用广泛。文章分析探讨了可控中子源补偿中子测井工作原理及仪器结构,并结合应用实例,阐述了可控中子源补偿中子测井在岩性识别、煤质分析、孔隙度分析及气层识别中的应用。提出了可控中子源补偿中子测井能有效地适用于煤层气测井评价的作用。CNL is a widely used method in CBM evaluation. This paper discusses the working principle and instrument structure of CNL of controllable neutron source. According to a real example,the application to rock type identification,coal quality analysis,porosity analysis,and gas reservoir recognition is analyzed by using the CNL of controllable neutron source. The results show that CNL of controllable neutron source can be effectively applied for CBM evaluation.
