为了搞清石油钻井作业生产性噪声的污染情况,以便掌握规律为防治提供科学依据,我们深入石油钻井作业现场,对噪声进行了专题调查。一、内容及方法从42个井队中随机抽样四个井队,对其各工种作业点及噪声源的噪声强度进行测量,并对噪声源噪声进行频谱分析。测量按《工业企业噪声检测规范》进行,使用国产JS-1型精密声级计,NL-5型倍频程滤波器和HF-1型活塞发声器,经中国计量科学研究院校准,并于每次测量前后均用活塞发声器对声级计进
In order to understand the pollution situation of production noise in oil drilling operations and to provide scientific evidence for prevention and control in order to grasp the laws, we conducted in-depth drilling operations and conducted a special survey on noise. I. Contents and Methods Four wells were randomly sampled from 42 wells to measure the noise intensity at work points and noise sources of each type of work and carry out spectrum analysis on the noise source noise. The measurement was carried out according to the “Noise Test Specification for Industrial Enterprises”. The domestic JS-1 type precision sound level meter, NL-5 type octave filter and HF-1 type piston sounder were used and calibrated by China Metrology Institute. Before and after each measurement, the piston sounder was used to measure the sound level
