摘　　要：当前姬塬油田开发过程中高含水率以及水驱方向不明等问题比较突出,急需通过示踪剂监测技术来探明注入水的推进速度及方向、确定注采井间连通性及层间突进等情况。微量物质示踪剂井间监测技术应用于鄂尔多斯盆地J井区,通过示踪剂产出曲线的形态特征分析和微量物质示踪剂定量解释,结合示踪剂前缘水线推进速度、注入水油井分配情况分析,明确了研究区井组示踪剂连通性和推进速度、渗流通道特征和非均质性。研究结果表明,监测区有8口油井受注水井J1控制,注入水突进方向整体偏北,注入水主流通道以高渗条带为主,层内和层间非均质矛盾较强,建议采用温和注水方式。In the current development of Jiyuan Oilfield,problems such as high water cut and unclear water-flooding direction are more prominent.It is urgent to use tracer monitoring technology to detect the advancing speed and direction of injected water,determine the connectivity between injection and production wells,and interlayer penetration,etc.In this paper,the tracer interwell monitoring technology is used in the J well area of the Ordos Basin.Through the morphological characteristic analysis of the tracer output curve and the quantitative interpretation of the tracer,combined with the tracer front waterline advancing speed,the analysis of the distribution of water-injected oil wells has clarified the tracer connectivity and advancing speed of the well group in the study area,the characteristics of seepage channels and the heterogeneity.The research results show that there are 8 oil wells in the monitoring area under the control of water injection well J1,and the direction of injection water intrusion is generally northerly.The main flow channel of injected water is mainly high-permeability strips,and the heterogeneity contradiction between layers is strong.Therefore,moderate water injection is recommended.
