针对目前示踪剂解释方法解释定量差、人为处理参数过多、无法处理多井以及多层问题,并且数值软件过于繁琐、工作量大、计算周期长、数值模型不过关、解释参数的可靠性差等缺陷,从油藏工程的角度,基于流线方法和不稳定渗流场,构建了更为完善的井间示踪产出浓度计算求解半解析方法体系,包括压力场求解、质点追踪方法和流场分解方法等,将三维问题的求解处理为一维问题解的组合形式.研制了基于流线求解方法体系的示踪剂测试解释软件,形成了一套实用可靠的示踪剂测试解释方法,在国内某一断块油田矿场测试应用中取得了较好的效果.%At present, focusing on the following problems for tracer interpreting methods; poor quantitative interpretations, much more man-processed parameters, no ways to process multiwell and multilayer, too tedious and complicated simulating software, large work load, long calculation period, not up-to-standard simulating models, poor reliable interpreting parameters and so on, from the viewpoints of oil reservoir engineering and based on streamline method and unstable filtration field, the semi-analytical system with much more perfect concentration calculating resolution for interwell produced tracer is established, including pressure field resolution, particle tracing method, flow field decomposing method and so forth, so the solution-seeking combination form can be changed from 3D to one-dimension. And furthermore the interpreting software of tracer test is developed on the basis of the system of streamline resolving method, so a set of practical and reliable tracer-test interpreting methods are formed, much better results are obtained in the application of field test in a fault-block oilfield at home.
