摘　　要：放射源在煤田测井中的应用,主要是通过测量地层对放射源释放的伽马射线的散射而进行岩性的划分、泥质含量和地层孔隙度的确定及煤岩层深度和厚度的判定。测井仪器会记录地层对伽马射线的散射强度,通过分析数据来划分岩性、确定煤岩层的位置和特征等。对放射源的安全使用极其重要,要符合相关辐射安全标准和规定,作业人员遵守操作规程,确保周围环境及操作人员的安全。The application of radioactive sources in coalfield logging mainly involves dividing lithology,determining shale content and formation porosity,and determining the depth and thickness of coal layers by measuring the scattering of gamma rays released by the radioactive source in the formation.Logging instruments record the scattering intensity of gamma rays from the formation,analyze data to classify lithology,determine the location and characteristics of coal and rock formations,and so on.The safe use of radioactive sources is extremely important,as they must comply with relevant radiation safety standards and regulations.Operators must follow operating procedures to ensure the safety of the surrounding environment and operators.
