钻井作业噪声治理技术研究

Research on Noise Control of Drilling

钻井作业使用大功率的动力设备会产生持续的噪声,从而对井场周边的居民生活造成影响。通过降噪技术研究和方案筛选,形成了适用于钻井噪声控制的三种方案:声屏障、隔声罩、低气压静音房。其中低气压静音房方案,房体整体封闭,通过排风口和进风口使空气定向流动,在房体内形成低气压,在保障设备散热的同时,能使噪声排放满足国标GBZ/T 189.8要求,井场边100 m处噪声达到国标GB 3096要求。

The use of high-powered power equipment for drilling operations will generate continuous noise, which will have a negative impact on the lives of residents around the wellsite. Through noise reduction technology research and scheme screening, three schemes suitable for drilling noise control have been formed： sound barriers, acoustic enclosures, and low-pressure soundproof room. In the low-pressure soundproof room solution, the house body is completely enclosed, air directly flows through the air outlet and the air inlet, and a low air pressure is formed in the room body. While ensuring the heat dissipation of the equipment, the noise emission can meet the requirements of the national standard GBZ/T 189.8. The noise at 100 meters away from the wellsite has reached the national standard GB3096 requirements.
