同位素示踪剂井间监测技术在狮子沟油田N1油藏的应用

将同位素示踪剂井间监测技术应用于青海油田中低渗透油藏，评价井间连通性，解释高渗通道参数，为油田挖潜增效提供依据。该技术采用定性分析和定量计算的方法并结合油藏的静、动态资料，对注水井与采油井间连通性和高渗通道的参数进行综合分析，提出合适的解释结论。实际应用表明，同位素示踪剂井间监测技术在中低渗透油藏分析井间连通性、识别高渗通道，解释高渗通道参数方面非常有效。

Application of Isotope Tracer Interwell Monitoring Technique in N1 of Shizigou Oilfield

The isotope tracer were injected into mid-low permeability reservoir of Qinghai oil field using inter well tracer monitoririg technique to evaluate the connectivity of between wells, explain the parameter of high-permeability channels, provide information for exploitation of oil filed. This technique adopt the method of qualitative and quantitative analysis, combining static datum and dynamic datum of reservoir to analyze connectivity of between injection wells and production wells, as well as the parameter of high-permeability channels. In fact, the application show it is very efficiency that the technique analyze connectivity between wells, identify high-permeability channels, and explain the parameter of highpermeability in mid-low permeability reservoir.
