水平井分段体积压裂后各段产液贡献不易测试和计算。通过分析示踪剂法测量的原理，进行了示踪剂测试技术优化研究，形成了利用示踪剂评价水平井分段产液贡献率的测量方法。应用该方法在束鹿凹陷致密油体积压裂井束探2x井进行了测试，优选了7种不同示踪剂分别注入7个压裂层段，通过分析在不同时间取得的246个样品，得到了7个层段的产液贡献率，为体积压裂优化设计和产能评价提供了新的方法。

It is not easy to test and calculate produced liquid of segments of horizontal wells upon segmented volume fracturing. Optimization research is conducted on tracer testing technology through analysis of the principles of measurement by tracer method, and the measuring method of using tracer to evaluate contribution rate of produced liquid of segments of horizontal wells is developed. The method is applied to testing for Shutan well 2x under tight oil volume fracturing in Shulu Depression, and 7 different types of tracers are selected and injected to 7 fracturing layers. 246 samples are obtained at different times through analysis, and contribution rate of produced liquid of 7 layers are obtained, providing a new method for optimization design and productivity evaluation under volume fracturing.
