摘要
套管井脉冲中子测井仪通过测量中子与地层中原子核核反应释放的伽马射线或剩余中子,得到饱和度、密度、孔隙度、水流流速、元素含量等信息,实现剩余油气评价功能。概述脉冲中子测井仪测井原理,说明了仪器各组成部分及作用,并通过描述国内外大型油田服务公司相关仪器发展过程及现状,综述套管井脉冲中子测井仪的发展历程,以期为中国脉冲中子测井仪器发展,从仪器设计及发展方向方面提供建议。
Pulsed neutron logging tools measure gamma rays or residual neutrons,after kinds of neutrons react with nuclei in formation,to deduce various formation information,such as saturation,density,porosity,flow speed,elemental content,etc.This study summarizes the principle of pulsed neutron logging tools.The main components and the function have been also illustrated.Based on the history of the pulsed neutron tool of the main oilfield service companies across the world,summarizes the development of cased-hole pulsed neutron logging tools,which can be used to assist the corresponding improvement in China,from the aspect of tool design and development direction.
