Noise Hazard Analysis and Control of Drilling Rig in Oilfields
Objective To find a reasonable solution to the problem of noise hazard of drilling rig in oilfields. Methods A diesel-driven borehole operator in an oil and gas field was selected as the research object. Through vibration and noise testing,the main noise sources and transmission paths of the TJL-12 borehole operator were analyzed. Sound insulation and sound absorption were carried out on the cockpit and engine room,and noise reduction and modification were car-ried out on the regulating valve to reduce the noise contact level,making it lower than the national occu-pational exposure limit requirements,and improving the oil and gas underground operating environment. Results The noise detection results showed that the dril-ler contact noise intensity decreased from 95.2 dB(A) to 84.2 dB(A),which was lower than the noise expo-sure limit of 85 dB(A). Conclusion Noise hazard anal-ysis and comprehensive treatment scheme can effectively solve the problem of noise hazard control of drilling rig during workover operation in oilfield industry.
