| 摘 要： | 通过恰当地设计测井仪结构、中子发射时序以及能谱和时间谱采集方式,可以构成集碳氧比、中子寿命、氧活化3项功能于一体的脉冲中子伽马综合测井仪.与碳氧比测井仪相比,综合测井仪增加了实时测量地层热中子宏观俘获截面、近远探测器非弹性散射及俘获伽马计数率比值、连续氧活化等功能,测井资料能在岩性、泥质含量、孔隙度、饱和度、层位产水等方面提供更丰富的实用信息.

| Abstract: | With proper designs of tool configuration, neutron burst sequence, as well as acquisition of energy and time spectra of gamma ray, an integrated pulsed - neutron gamma ray logging tool, which involves carbon/oxygen logging, neutron lifetime logging and oxygen activation logging, is constructed. Besides curves from a traditional carbon/oxygen tool, the integrated tool can simultaneously provide curves of the thermal neutron capture cross section of the formation, the count rate ratios of near/far inelastic, and capture gamma rays, and the oxygen activation. The plenty of data is applicable to evaluation of lithology, shale volume, porosity, saturation, and water entries. |
