| Zusammenfassung: | The invention discloses a multi-section fracturing tracing interpretation method which comprises the following steps: S1, considering a tight reservoir horizontal well multi-section fracturing tracing huff and puff process, and establishing a single-section output concentration model through a multi-phase flow diffusion equation in multiple pores, multiple media and multiple directions in different stages; s2, on the basis of the single-section output concentration model established in the step S1, a multi-section output concentration model is established, and a tight reservoir horizontal well multi-section fracturing tracing response mathematical model is obtained; and S3, through dynamic fitting of parameters, the result of the tight reservoir horizontal well multi-section fracturing tracing response mathematical model established in the step S2 is verified. According to the method, a fracturing tracing explanation mathematical model is perfected, the explanation result better conforms to an objective law, |
