明确油水井的对应关系、注入水驱方向及驱替速度、油层非均质性状况、识别大孔道或微裂缝,对示踪剂在安塞油田的适应性进行分析。介绍示踪剂监测原理及应用示踪剂监测剩余油饱和度,对示踪剂监测结果在安塞油田的应用情况进行分析。井间示踪剂监测在油田不同开发阶段和应用方面表现出不同的适应性。建议在安塞油田利用示踪剂监测剩余油饱和度。井间示踪剂监测能有效地评价油藏连通性、注入水流动方向,是制订油田开发方案的重要依据。
The corresponding relationship between oil and water wells was clarified, waterflooding direction and displacement speed were injected, the heterogeneity of reservoir was identified, and macropores or microcracks were identified. The adaptability of tracers in Ansai oilfield was analyzed. The principle of tracer monitoring and the application of tracer to monitor the residual oil saturation are introduced. The application of tracer monitoring results in Ansai Oilfield is analyzed. Cross-well tracer monitoring shows different adaptability in different development stages and applications of the field. It is recommended to monitor the remaining oil saturation with tracer in Ansai Oilfield. Crosswell tracer monitoring can effectively evaluate reservoir connectivity and inject water flow direction, which is an important basis for formulating oilfield development plan.
