摘　　要：生产动态测井是油田监测的重要措施,目前对其系统性应用研究较少。以七参数生产动态测井技术为例,对该测井技术进行了简要介绍,并对其在注水油田中的应用进行了全面、系统的总结。七参数生产动态测井技术现场应用体现在以下5方面:①基于涡轮转速变化情况识别管柱状况;②通过小层产量劈分评价合采储层有效性;③通过动静态组合测井识别有效裂缝;④基于时移生产动态测井监测水淹动态;⑤基于注入剖面测井的非均质储层注入能力评价。实践表明,生产动态测井在油田动态监测中具有良好的应用效果,可为油田生产措施的制定与调整奠定基础。Production logging is an important measure for production performance monitoring in oilfield,yet studies on its application are still at the infant stage.This paper takes the seven-parameter logging technology as an example to briefly introduce its working principle and symmetrically summary its application in oilfield water flooding.The seven-parameter logging technology is applied in the field mainly in the following 5 aspects:①Identification of the string conditions based on the change of turbine speed;②Evaluation of the effectiveness of commingled production of reservoirs by production splitting from separated layers;③Identification of the effective fractures by combination of dynamic and static loggings;④Monitoring water flooding performance based on time-lapse production dynamic logging;⑤Injection capacity evaluation of heterogeneous reservoirs based on injection profile logging.Practice shows that the production dynamic logging has a promising prospect for application in oilfield dynamic monitoring,which can lay agood foundation for the making and adjustment of oilfield production measures.
