Disclosed are a green cleaning-thermal desorption integrated technology treatment method and system for high-concentration petroleum sludge. The method comprises the treatment steps of homogeneous impurity removal pretreatment, chemical thermal washing treatment, solid-liquid separation and petroleum-water separation, petroleum sludge thermal desorption and high-temperature combustion and oxidation, heat exchange and tail gas cooling and dust removal. The system comprises a petroleum sludge chemical thermal washing system and a petroleum sludge decontamination thermal desorption system. The petroleum sludge chemical thermal washing system is formed by connecting a petroleum sludge homogenization tank (1), a petroleum sludge chemical thermal washing tank (2), a high-efficiency solid-liquid separator (3), an petroleum-water separator (4), a sewage integrated treatment system (6) and a water storage tank (23) successively. The petroleum sludge decontamination thermal desorption system mainly consists of a sludge
