摘　　要：大庆喇萨杏油田主力油层均已进入高含水后期,针对高含水后期调整挖潜的剩余油评价难题,根据密闭取心与井壁取心对比分析实验资料、试油及投产资料,建立了以地化色谱、荧光显微图像分析等新技术为手段的水淹层录井评价技术体系。该项技术受储层非均质性的影响较小,可直观、准确地评价剩余油,进而确定剩余油的挖潜部位。经过几年的发展、改进和完善,该项技术逐渐成熟,实现了评价技术的有形化,完成了从技术方法向现实生产力的转化,且应用灵活、方便,在新钻调整井中应用见到了明显的效果,成为在高含水主力油层深化挖潜和薄差层有效动用过程中,剩余油评价和射孔选层的关键技术之一。应用本文建立的水淹层解释评价方法,在喇萨杏油田新钻调整井中解释632口井,综合解释符合率为86.7%,依据录井资料拟定射孔方案进行投产,应用效果较好。The major reservoirs of Daqing Lasaxing oilfields have entered later stage of high water cut.In consideration of the challenge of evaluation of remaining oil during the adjustment and potential tapping in the later stage of high water cut,logging assessment technical system of the water flooded zones is established,which consists of new technologies of geochemistry chromato and fluorescent micro-image analysis and so on ,based on experimental data of the comparision between sealed coring and sidewall coring and data of oil test and commissioning.This kind of technology is less affected by the reservoir heterogeneity,which can evaluate remaining oil intuitively and precisely ,furthermore define the site of the potential tapping of the remaining oil.After several years of development,improvement and gradual mature,the assessment technique is tangible,which accomplishes transformation from technological methods to real productivity.It has apparent ef- fect in the application of the newly drilled adjustment wells with flexible use and convenience.It is the core technology of evaluating the remaining oil and perforating and selecting oil layers during the process of tapping the potential of the major reservoirs at high water cut stage and efficiently producing of poor layers.After the assessment technique of logging interpretation introduced above in this paper is applied, 632 wells are interpreted among the newly drilled adjustment wells in the interpretation is 86.7%.The result is good after scheme worked out by logging data. Lasaxing oilfields,and integrated coincidence rate of putting into production according to the perforation
