The former understanding about actual hydrocarbon migration paths is mainly based on the micro-scale physical simulation or the computer simulation, and the actual oil and gas migration paths only rely on indirect evidence. This paper takes Puwei area of Dongpu depression as an example, firstly we find out the dominated migration pathways of main sandbodies and faults, then analyze their relationships with hydrocarbon kitchens and reservoirs to evaluate their effectiveness, and lastly identify the paths of hydrocarbon migration by combining the tracking of nitrogen compounds indicators. The results show that ridge-like structures analysis combined with geochemical indicators tracking can identify actual hydrocarbon migration paths accurately.
