宁东油田矿山地质环境保护与恢复治理的建议

Mine Geological Environment Protection and Restoration in Ningdong Oil Field on Ordos Basin

为缓解宁东油田合理开发与地质环境问题的矛盾,基于"3S"技术并现场调查宁东油田的地质环境背景及特征,采用工程类比法参考临近油田评估结果,针对该油气田地质环境进行现状与预测评估,查明该油气田的开发主要造成土地资源占压与地形地貌损毁的不良地质问题,而其水文地质及地质灾害问题影响较轻。针对上述不同影响程度的地质环境问题,提出场地整理+植被绿化的综合治理方法进行治理,并开展水文地质监测工作,有利于该油气田的地质环境的保护与恢复治理,对其可持续开发具有重要实际价值与指导意义。

Recently, the contradiction between exploitation of mine resources and the destruction of geological environment has become increasingly signifcant. It is one of obstacles to normally explore the mine. Thus, in order to reduce the negative impacts which had been surveyed with ‘3S’ technology and feld work, according to relevant standard, the scheme had been complied to protect and restore the mine geological environment in Ningdong oil feld on Ordos basin. The exploitation has main negative impact on land resources, topography and geomorphology with minor impact on aquifer and geological disasters. For the sake of the protection and restoration, it proposes measures of restoration by feld grading and vegetation planting with groundwater monitoring, which will be in favor of sustainable exploitation.
