摘　　要：以PNST脉冲中子全谱测井仪为基础,通过优化源距、屏蔽体尺寸,改进中子发生器等,研制了PNST-3D测井仪。介绍了PNST-3D剩余油饱和度测井技术的工作原理,分析了各种测井模式的测量原理和技术应用。结果表明,PNST-3D的实测能谱与模拟能谱相互一致,测井结果与全谱PNST的解释结果相符。Based on the PNST tool, the PNST-3D pulsed neutron logging tool is constructed through optimizing the source distance, shielding size and improving the pulsed neutron generator. The principle of the PNST-3D logging technology is introduced, the measuring principle and application of various logging modes are analyzed. The result shows that the measured energy spectrum is consistent with the simulated energy spectrum, logging data is consistent with the results from PNST.
