某气田增压站压缩机组噪声治理效果分析

Noise Governance Effect Analysis of Compressor-unit in a Gas Field Booster Station

针对川东地区大多数增压场站存在的厂界噪声超标问题,以某气田增压站为例,从生产设备、厂界范围入手,分析了压缩机组噪声超标点位,提出了噪声超标治理方案。经现场改造后,噪声排放满足GB 12348—2008《工业企业厂界环境噪声排放标准》二类昼间≤60 dB(A),夜间≤50 dB(A)的要求。该压缩机组降噪治理应用有效降低了噪声水平,符合国家环保政策,为气田后期开发提供参考。

Aiming at the problems of excessive noise at the boundary of the most pressurization booster stations in eastern Sichuan,this paper took the a gas field pressurization station in PetroChina southwest oil and gas field company as an example.Starting from the compressor device,station bound scope and other aspects,the exceeding sites of compressor-unit noise were analyzed,and the noise management program was raised.After improvement of the station,noise emissions meets the requirements of GB 12348-2008"Environmental Noise Emission Standards for Industrial Enterprises and Plant Boundaries",Category Ⅱ in daytime ≤60 dB(A)and nighttime≤50 dB(A). The noise reduction governance application of the compressor-unit effectively reduced the noise level,conformed to the national environmental protection policy,and provided certain reference value for the later development of the oil and gas field.
