An efficient petroleum degradation composite bacterial agent is provided, comprising the following effective microorganisms: Tsukamurella pulmonis ECO 17 with accession number CGMCC No. 15837; Bacillus paramycoides-3 with accession number CGMCC No. 16238; Sphingopyxis chilensis-13 with accession number CGMCC No. 16241; Achromoobacterpulmonis-10 with accession number CGMCC No. 16240. In the present invention, degradation strains are screened according to the degradation characteristics of the strains to petroleum hydrocarbons. The four strains have different degradation characteristics to petroleum hydrocarbons of different carbon chain lengths. Moreover, the four strains do not competitively inhibit growth after being compounded, and achieve a synergistic promotion effect, so that the degradation efficiency of petroleum hydrocarbons can be improved. 1
