淮南煤田三维地震勘探技术应用进展
|
摘要
淮南煤田地处华北型石炭二叠纪聚煤区的东南部地区,煤系地层为石炭二叠系。淮南矿业集团与产学研等多家单位合作,积极研究与推广应用三维地震勘探技术。自1993年谢桥矿首次开展煤炭采区三维地震勘探以来,至目前的高密度三维地震勘探,历经6个发展阶段,开展了针对不同煤层的精细处理、厚煤层屏蔽下的下伏煤层勘探技术、AVO技术、岩性反演技术及高密度三维地震勘探等多项科研项目,取得了丰硕的勘探成果。根据淮南矿业集团探采对比资料,指出了采区三维地震勘探的研究方向及应采取的措施。
The Huainan coalfield is situated in the southeastern part of North China type Permo-Carboniferous coal accumulation area,coal measures strata belong to the Carboniferous and Permian systems.The Huainan Mining Group cooperated with multiple industrial units,universities and research institutes,and actively studied,popularized and applied the 3D seismic prospecting technology in practices.Since the first launching of winning district 3D seismic prospecting in the Xieqiao coalmine in 1993,up to high density 3D seismic prospecting at present has experienced 6 developmental stages.Aimed at different coal seams,have carried out multiple scientific research projects including fine processing,prospecting technology of thick coal seam guarded underlying coal seams,AVO technology,lithologic inversion technology and high density 3D seismic prospecting,have obtained plentiful and substantial prospecting results.Based on the data from Huainan Mining Group's correlations of exploration and mining information,pointed out the research orientation of winning district 3D seismic prospecting and measures should be adopted.
