摘要
煤层气地面开发过程中对环境的影响主要体现在钻井过程中钻井液的使用及钻井过程中对地下水的影响;钻井泥浆池对地表水威胁;采排水对地表水环境的影响;钻井泥浆处置;地面开发活动过程中地表开挖对自然生态环境、农业生态环境的影响。通过针对性的防护对策,可使煤层气地面开发活动对环境的影响降至环境可接受范围内,使经济效益、社会效益和环境效益有机统一,实现社会和环境可持续发展。
The ground development of CBM has important influence on environment. These influences chiefly embody at several aspects： the using of drilling fluid, the effect of drilling on groundwater during the process of drilling, the mud pit＇ s threats to surface water, the influence of draining on surface water environment, the disposal of drilling mud and the effect of surface excavation on natural and agricultural ecological environment. Therefore some pertinence countermeasures must be adopted to reduce influence of CBM ground development on environment to the acceptable level, which will strongly promote the organic unity of social, economic and environmental benefits, and realize eventually social and environment sustainable development.
