“…To provide a more comprehensive characterization of the flow behavior of fracturing fluids, the combination of residence time distribution analysis (RTDA) and downhole tracers can be utilized. This approach allows for the determination of the transit time from the fracture to the surface for each tracer segment, providing insights into the flow dynamics of the fracturing fluid . In the context of multiphase flows, numerical simulation methods can be used to model the migration of tracers and radionuclides through heterogeneous fractured rocks in nonisothermal multiphase systems .…”

Multistage fracturing is widely used in the development of tight oil reservoirs, and the fine description of postfracturing fracture networks is a challenge in tight oil reservoir development. Based on the formation mechanism of dual-wing fractures and the principles of tracer flowback, a mathematical model for tracer concentration in dual-wing fractures is established by considering the convective diffusion of the tracer within the fractures. An interpretation method for tracer flowback curves, utilizing a combination of Gaussian fitting and theoretical equation inversion, is developed to provide a detailed description of fracture parameters such as fracture half-length, fracture width, and fracture conductivity in the postfracturing fracture network. This method can be rapidly applied in field practices. Application examples demonstrate that the relative errors between the calculated cumulative oil and water production using this method and the actual data are less than 5%, validating the accuracy and applicability of the established mathematical model for tracer flowback and the interpretation method for tracer concentration curves in addressing practical problems.
