摘　　要：构造油藏开发中后期含水上升快,稳产技术措施必须进行合理调整,开展好精细地质研究,尤其是充分利用现有常规测井资料开展油水界面识别和油藏剖面特征研究十分重要.本文基于文献调研,结合研究区(Z区)地质资料、测井资料和动态生产资料,开展了油水界面识别方法研究,并对现有测井资料按照测井时间进行合理分段研究,提出基于时间推移的油水界面确定方法和油藏剖面动态特征研究方法,得到了工区油水界面动态变化特征.研究表明,基于自然伽马、自然电位和感应测井方法可以较好地识别工区目的层油水界面,按照测井时间合理分段可以更准确地实现对油水界面变化的动态分析,基于时间推移的油水界面研究方法简单有效.本文研究成果对邻区具有一定的参考作用.The technical measures of stable yields have to be rightful regulation, because the containing water moves upward fast while the developing of intermediary and later stage. It is important that identifying oil/water boundary and studying the reservoir section feature using of conventional logging data. The method of identifying oil/water boundary has been researched on the base of documents published surveyed and studied, referring to geological information and logging data and dynamic means of production in the Z region. Moreover, logging data has been studied according to reasonable fragment of logging time, the method of the identifying oil/water boundary and the analysis reservoir section dynamic feature has been advanced based on time-lapse, then, the feature of OWC alteration have been obtained. Research indicated that the OWC could be identified with the method of GR and SP and induction log, the reservoir dynamic analysis of OWC change could be accurately studied on the reasonable fragment of logging time, the method is easy and effect.
