Abstract Objective To understand the occupational hazards caused by the workover operation of an oil production plant, and put forward some suggestions for the prevention and control of occupational diseases.Methods According to national standards, the methods of field investigation, detection and combinational analysis in the workplace were used to evaluate the project.Results The main occupational hazard factors in workover job of oil production plant are dust, formaldehyde, acetaldehyde, butyraldehyde, phenol, Benzene, methylbenzene, dimethylbenzene, asbestos fiber and noise. The concentrations of hazardous substances met the requirements of the occupational limits in the workplace. But noise intensity from workover rig exceeded the Occupational allowable limits.Conclusion Formaldehyde, lead dust and noise are the main occupational hazards in Oilfield workover operations, of which noise nuisance is worse. Effective measure,such as innovating technology and strengthening individual protection should be take.
