摘　　要：为减少页岩气勘探成本、降低勘查风险,兼顾页岩气开发的环境效应问题,首次将GIS与RS方法应用到重庆市酉阳东页岩气勘查区块钻探场地选址中。选择了坡度、道路、断层、地质调查线路、地质灾害和禁止勘查/开采区等6个因子,采用"一票否决"的方法,通过叠加分析得到了钻探场地适宜区;综合考虑土地利用、水系和有效面积等参考因素,进行了钻探场地的进一步优选,并以ArcGlobe软件为三维展示平台,实现了工作区虚拟显示。结果表明,该方法充分考虑了自然地理条件对钻探场地选址的约束,剔除了政策限制区域,兼顾了地质基础,选址结果为后期实地的钻场选址指出了方向,地表三维可视化的展示方法可为野外调查、勘查部署等工作提供辅助决策支持。In order to reduce the cost and risk of shale gas exploration, as well as giving consideration to the environmental effect caused by the shale gas development, this paper firstly proposed a spatial location method combining GIS and RS to select the drilling field for shale gas exploration area in east Youyang,Chongqing. This study chose six factors which are slope,roads, faults, geological survey lines, geologic hazards and the forbidden exploration/development regions,and took the method of ＂one ballot veto＂ to obtain the areas suitable for drilling field by spatial overlapping. By comprehensively considering the reference factors such as land use, water system and the effective area, the drilling fields were further selected. Based on ArcGlobe 3D platform,the whole workspace was virtually displayed in a 3D environment. It was concluded that the proposed method could provide a direction for the further field drilling site selection; by putting the surface in 3D visualization,it could provide auxiliary decision supports for field survey, exploration deployment, etc.
