摘　　要：文中以苏仁诺尔油田为例,分析了主要产油层南屯组精细解释技术的应用效果.苏仁诺尔油田处在北东向苏仁诺尔构造带上,南屯组顶底界面及内部分界面(T23)为区域标准等时面,精细对比研究时参考局部等时面,可获得高精度地层格架.油田内断裂关系复杂,精细断层解释结果阐明了苏仁诺尔油田内部储层不连通、注采关系不对应等现象原因,以及对油田油气聚集规律产生的影响.采用多级次断裂空间配比关系来解决开发地质问题,同时结合生产动态资料反过来验证地质问题,对于油田开发过程中注采关系调整,剩余油分布特征研究具有一定指导意义.The precise interpretation plays an important role in the development stage of oilfields.This paper talks about its application in Surennuoer oilfield for example.Surennuoer oilfield locates in Surennuoer belt as a north-south trending.The Nantun formation is the main oil layer,which top or bottom interface and the inner interface（T23）are regional standard isochronal surfaces.In the development period the high resolution interpretation needs a reference for local isochronal surface.Seizing on wells and seismic characteristics can establish the high precision stratigraphic framework.In this field the faults are complicated.The lower class faults＇ occlusion makes the reservoir not be connected each other,the injection and production not match, and the oil-gas accumulation change,etc.In the course of precise seismic interpretation,the interlayer structure and more lower class faults can be identified.Meanwhile,the development geology problems can be verified by the production dynamic data.The results have a certain guiding significance to adjust the injection-production relation,and to study the accumulation and the distribution of remaining oil.
