遥感技术在复杂山区页岩气早期勘探中的应用

我国目前公开招标的页岩气区块多数位于四川盆地东南缘高陡构造带,地形复杂,断裂发育,造成区块内页岩气的勘探和开发均存在一定难度.与盆地内覆盖区的页岩气早期勘探不同,复杂山地内的页岩气早期勘探需考虑地表地貌因素,加强早期研究,降低勘探风险和成本.利用湖南保靖地区的页岩气招标区块的遥感数据,与DEM数据相结合,考虑坡度、高程2个因素,优选研究区页岩气勘探的地貌有利区,为下一步页岩气的勘探和后期施工提供参考.

APPLICATION OF REMOTE SENSING TECHNOLOGY IN EARLY EXPLORATION FOR SHALE GAS IN COMPLEX TERRAIN

Most of the shale gas blocks for open tendering in China are located within the high-angle structural belt in the southeast of Sichuan basin, where the geomorphology is complex, with developed faults, making the exploration and exploitation difficult. To reduce the risks and costs, the geomorphie factors have to be seriously considered in early stage of shale gas exploration. Based on the remote sensing data from Baojing shale gas block in Hunan Province, with synthesized gradient and elevation factors, this research optimizes favorable areas in this block and provides a reference for further exploration and surface engineering.
