| 摘 要： | 随着我国一系列鼓励煤层气开发政策、规划的实施,区域煤层气规模化和商业化开发将逐步展开.煤层气开发环境问题与常规天然气相比有其特殊性,主要表现为井网密度大、疏水降压排采和加压集输引发的特殊环境问题.井网密度大则对地表生态环境的影响大;煤层排水是煤层气开发区别于常规油气资源开发最主要的环境问题;加压集输和井网密度大增加动力设备,影响声环境质量和生态环境质量等.针对煤层气开发环境问题的特殊性,提出煤层气开发应以水平井为主减少地表扰动.不同水文地质条件煤层排水水质不同,我国为缺水国家,煤层排水如果为淡水,应考虑综合利用;如果为高矿化度水应考虑适当处理回注地下.

| Abstract: | With the implement of incentive policy and plan in coal bed methane(CBM) development,The widespread commercial exploitation of CBM will be conducted.The potential environmental issues which are different from natural gas are as follows:(1) to produce CBM,the water pressure must be reduced by pumping water from the coal,That means,large volumes of produced water will need to be disposed which may cause surface water contamination and groundwater withdrawal;surface discharge can grossly alter the natural hydr... |
