利用岩心、录井、测井、试油等动、静态地质资料，在精细地质认识的基础上，对高台子油层油水同层发育及分布特征、油水同层的动用状况及挖潜潜力进行了研究，并利用找水、试油、碳氧比能谱测井等资料分析成果对高台子油水同层的补孔界限进行了界定，研究得出：油水界面由北向南呈“∩”变化趋势，由西向东呈“∪”型变化趋势；油水同层部分层段已经动用，油水同层动用程度比纯油层差；油水界面储量纵向上主要分布在高Ⅰ组和高Ⅲ组，油水同层含水低于全井含水；剩余油类型主要以注采不完善型为主，需要通过完善注采关系来进一步提高油水同层的动用程度；确定了现阶段可以对油水同层补开的不同比例及挖潜深度界限，确保油水同层潜力得到充分动用。

Based on precise mastery of the geological condition, developmental and distributional characteristics of oil-water layer in Gao Taizi oil layer were analyzed as well as reservoir producing contidion and latent capacity by using dynamic and static geological data including core, mud logging, well logging and well testing. Meanwhile, the reperforating boundaries of Gaotaizi oil-water layer were defined by data analysis, such as water exploration, well testing and carbon oxygen spectral logging. The results show that, oil-water interface presents the trend like “∩” from north to south,and “∪”from west to east; part of oil-water layer has been exploited, the exploiting situation of oil-water layer is worse than that of oil layer; The reserves of vertical oil-water interface are mainly distributed in Group GaoⅠandⅢ,the water content of oil-water layer is lower than that of the whole well; The remaining oil was mainly caused by incomplete injection-production, the exploiting efficiency could be increased by improving the releationship between injection and production; The percentage of reperforation and depth of tapping the potential in oil-water layer have be determined, which can ensure the latent capacity of oil-water layer to be fully exploited.
