摘要: 针对传统示踪分析技术存在的问题,从理论方面着重探讨了多种示踪物质的运移特征及其影响因素,将示踪剂的一维弥散规律推广至三维形式,建立起精确描述示踪剂弥散与滞留、流体的重力、毛管力及任意油水流度比的数学模型,并与实验室大型平板五点井网模型的实测结果进行了对比分析,解释的结果与实测结果非常吻和.本项研究,对分析“控水稳油”工程措施和三次采油获得油藏和流体定量信息,意义重大.

Abstract: At first,some problems in the existing techniques used for the analysis of interwell tracers are reviewed;Then,the flow characteristics and effecting factors of various tracers are studied theoretically.The dispersion regularity of tracers in one dimensional homogeneous media is extended to the situation of three dimension- Based on the popularization,a mathematical model is built up,in which the dispersion and retardation of tracers,gravity of fluids,capillary pressure,and arbitrary mobility ratio of reservoir fluids are considered.Its simulation results are compared with the results of a big five-point laboratory plane model,and they may match well.It is also demonstrated that this study will take a very important part in "controlling water and stabilizing oil" and getting some quantitative information about the reservoirs and the reservoir fluids in tertiary recovery.

Key words: tracer, heterogeneity, phsical dispersion, partitioning factor
