【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。
[Abstract]:In order to reduce the cost of shale gas exploration, reduce the exploration risk and take into account the environmental effect of shale gas development, GIS and RS methods are applied to the site selection of Chongqing Youyang shale gas exploration block for the first time. Six factors, such as slope, road, fault, geological survey route, geological hazard and no exploration / mining area, were selected. By using the method of "one vote veto", the suitable area of drilling site was obtained by superposition analysis. Based on the reference factors such as water system and effective area, the drilling site is further optimized, and the virtual display of the working area is realized by using ArcGlobe software as the 3D display platform. The results show that the method takes full account of the constraints of physical and geographical conditions on the site selection of drilling sites, removes the policy restricted areas, and takes into account the geological foundation. The results of the site selection indicate the direction of the site selection in the later stage of drilling site selection. The display method of surface 3D visualization can provide auxiliary decision support for field investigation, exploration deployment and so on.
