摘　　要：为保证直升机安全起降 ,根据大气扩散理论、海区大气环境特点和工程情况估算了某气田中心平台排放塔高度应该大于 6 5m ,子平台排放塔高度应该大于 4 5m。贫可燃浓度和 1/10贫可燃浓度在排放口附近相近 ,在排放口下风方向差别较大。In order to assure the safety of the helicopter, according to the atmospheric diffusion theory, atmospheric environment character and project circumstance, the exhaust tower height at an oil gas field was estimated. The exhaust tower height of the central platform should be not high than 65 m, that of the sub platform should be not high than 45 m. The lean combustible concentration and the 1/10 lean combustible concentration are close at the emission point, and they have a great difference at the leeward of the emission point.
