某采油厂修井作业职业病危害调查与评价

目的 了解某采油厂在修井作业过程产生的职业病危害状况，提出相应的职业病防控措施建议。方法 依据国家相关标准，采用职业卫生调查、职业卫生检测、综合分析等方法进行综合评价。结果 采油厂修井作业过程中存在的主要职业病危害因素包括其他粉尘、甲醛、乙醛、丁醛、苯酚、苯、甲苯、二甲苯、石棉纤维、噪声等，工作场所产生的化学毒物职业病危害因素浓度均符合国家相关职业接触限值要求，但是修井机司机接触的噪声强度超过接触限值。结论 甲醛、铅尘及噪声是油田修井作业的主要职业病危害因素，其中噪声危害程度较为严重，企业应针对性地采取革新工艺，加强个体防护等措施进行控制。

Investigation and evaluation of occupational hazards in the workover operation of an oil production plant

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.
