某油田企业职业卫生状况调查

目的对某油田生产过程中存在的职业病危害因素进行调查，分析其危害程度，为采取合理的治理措施提供科学依据。方法现场职业卫生学调查，根据国家现行职业卫生标准对主要的职业病危害因素进行检测。结果该油田化学毒物总的超标率为0．25％，其中采油厂超标率为0．35％：粉尘检测均未超标；噪声强度总的超标率为34．0％。其中采油厂、原稳厂、销售储运系统、工程技术中心噪声超标率分别为38．3％，26．9％，15．2％，25．0％。结论该油田的化学毒物及粉尘浓度绝大多数达到了国家卫生标准，但噪声污染的治理措施存在设计不合理或不完善的地方．尚需加强治理。

The Investigation of Occupational Hazard Factors In the Oilfield Enterprise

Objective： To investigate the occupational hazard factors in the process of production in a oil-field, and analysis the degree of the endanger. We can provide scientific basis for the reasonable controlling efficiency. Methods： According to the current national occupational health standards for occupational hazard factors detection, occupational health investigation was proceeded. Results： The total exceeding rate of chemistry poisons was 0.25 percent, and the exceeding rate of the oil extraction factory was 0.35% ;The dust density was qualified; The noise intensity of 34.0% was 〉85 dB（A）,and the exceeding rates of noise intensity in oil extraction factory, crude oil stabilization factory, marketing and transporting system and the center of engineering were respectively 38.3% ,26.9%, 15.2% and 25.0% .Conclusion： The majority values of chemistry poison and dust in the oil-field meet with national health standards. But there are many illegitimate and incomplete aspects in the controlling efficiency of environmental pollution, and it must be brought under control.
