摘　　要：老油田进入开发中后期,依靠常规测井资料和生产动态资料进行剩余油监测难以满足生产实际的需要。脉冲中子全谱饱和度测试技术集碳氧比能谱、氯能谱、中子寿命、氧活化测试技术于一体,一次下井能录取多条曲线,多种测试资料相互印证,能够满足套后测试要求。将脉冲中子全谱饱和度测试资料与常规测井资料、生产动态资料有机结合,针对A区块制作了解释图版、制定了解释标准,提高了解释符合率,有效反映了储层剩余油饱和度的变化情况,为挖潜增储提供了可靠依据。For old oilfields at the middle and late development stages,it is not effective to detect remaining oil based on conventional logging data and production performance data.The pulsed neutron full spectrum saturation logging(PSSL)technology integrates carbon-oxygen ratio energy spectrum,chlorine energy spectrum,neutron lifetime,and oxygen activation testing technology.It can acquire multiple logs in one trip and adopts various testing data for cross-validation,allowing it to be qualified for post-casing testing.Combining the PSSL data with conventional logging data and production performance data,the interpretation chart and interpretation standard were made for Block A,which help improve the interpretation coincidence rate and effectively reflect the changes in remaining oil saturation of the reservoir.The PSSL technology provides a reliable basis for tapping potential and increasing reserves.
