摘要
目前,煤层气田集输系统防火间距遵循常规天然气田的相关规定,防火间距偏大,存在集气场站选址困难、占地面积大及浪费土地资源等问题。为此,开展了煤层气田集输系统放空影响范围研究。分析了大气稳定度和风速2项环境因素对放空后果的影响,研究了不同放空速率下煤层气井场和站场的放空后果影响范围,进而得出煤层气放空后果的最大可能影响范围,为今后优化煤层气集输系统布局,合理节省工程占地的研究提供有价值的参考。
Currently, the fire protection distance of gathering system in coal bed methane(C BM) field follow the relevant regulations of conventional natural gas field, thereby the fire protection distance is large, which create a lot of problems as difficulty in sitting of station, the waste of land resources and other issues. For this reason the study of influence area of gas-release in CBM is developed. This study analyzes two environmental factors, which are atmospheric stability and wind speed, to obtain their impact on fire protection distance. Then, it compares the influence area of well site and gas station respectively under different gas release-speed condition. Finally, it obtains the maximum possible influence range, which can provide some references to optimize the system layout and save a reasonable land occupation in the project.
