由胜利油田测井公司和华东石油学院勘探所协作研制了SCN86型低源强补偿中子测井仪。在双方科研人员的共同努力下,经过一年多的研制和不断改进,从1987年6月起,已连续测出数条合格曲线,一次成功率为100%。 SCN86型低源强补偿中子测井仪采用为低源强专门设计的结构和电子线路,与带有专用低源强处理软件的MCB—GNT数控面板配合,在使用4.5居里镅铍中子源的情况下,其测量精度、分层能力、测量范围和稳定性均十分接近于使用18~24居里中子源的
Developed by Shengli Oilfield Logging Company and Exploration Institute of East China Petroleum Institute, SCN86 low-source-strong compensated neutron tool was developed. With joint efforts of researchers and researchers, after more than a year of research and continuous improvement, several conforming curves have been continuously measured since June 1987 with a success rate of 100%. The SCN86 low-source-strength compensated neutron tool uses a specially designed structure and electronics for a low source strength that works with a MCB-GNT CNC panel with a dedicated low-source-strength processing software that uses a 4.5-Curie 镅 beryllium neutron Source, its measurement accuracy, delamination ability, measurement range and stability are very close to the use of 18 ~ 24 Curie neutron source
