According to the New Oriental Postgraduate Entrance Examination Network, in 2023, the number of graduate students in Southwest Petroleum University was 4.73 million, and the enrollment ratio was 5.7 1. The higher the enrollment ratio, the fiercer the competition. On the contrary, the smaller the proportion, the smaller the competition, which explains the difficulty of successfully landing the postgraduate entrance examination to a certain extent, so the lower the admission ratio, the better. The Graduate School of Southwest Petroleum University was established in 2005. Southwest Petroleum University began to train graduate students in the 1970s, and was granted the right to confer doctoral degrees in the 1980s.
