摘　　要：以苏丹×油田1口生产井A井为例,采用SLP潜油电泵机组与ZENITH的Y-TOOL井下工具配套进行测井。综合运用采集到的固井质量资料、过套管电阻率资料、产液剖面生产测井资料和脉冲中子-中子测井资料,识别和确认了A井的水淹层位,分析和评价了该井的井下生产动态。在定量评价A井剩余油饱和度的基础上,引入油层采出程度的参数。深入分析研究该井开发动态中的油层采出程度,有效区分了主力产层和未动用层,指明了该井后续的剩余油开发层位。通过对脉冲中子-中子测井资料和过套管电阻率测井资料进行分析,其解释结果既相互吻合,又互为佐证。实现了在同一口井中检验过套管电阻率测井和PNN测井技术的可靠性、一致性和有效性。Y-TOOL joint logging technique, which is combined with ESP（Electric Submersible Pump）and BYPASS sections, has been successfully applied in production well A of × oilfield in Sudan. Qualified CBL （Cement Bond Tool）, ECOS （Resistivity Logging after Casing）, PLT （Production Log Tool） and PNN （Pulsed Neutron-Neutron） logging data have been comprehensively studied in this well. Flooded zones are confirmed and dynamic producing situation in the borehole of well A is analyzed. Moreover, oil producing degree is used to evaluate the main producing zones and potential zones in order to provide potential targets for the following development plan based on quantitative evaluation of remaining oil saturation. Besides, qualified ECOS and PNN logging data, acquired together from one same well, shows consistent results between each other based on back-to-back data analysis, which verifies the validity and reliability of ECOS and PNN logging techniques.
