贵州正安奥陶-志留纪之交五峰——龙马溪组黑色页岩的划分与对比
|
摘要
近年来我国南方下古生界海相页岩气勘探开发取得重要进展,国土资源部已在黔北地区建立了页岩气综合勘查试验区。根据贵州正安安场向斜安页1井井下奥陶系-志留系之交的五峰组—龙马溪组的笔石划分了笔石带,同时对焦页1井等有良好页岩气产量的井进行了井下地层对比,确定了正安可能成为页岩气储层的五峰组和龙马溪组下部WF2~LM5笔石带序列。同时还对安场向斜的堡上村剖面进行了观察,结果显示,该剖面龙马溪组黑色页岩顶部LM5带的笔石,可作为安页1井黑色页岩层段顶界的参照。
Important progresss has been made in Lower Paleozoic marine shale gas exploration and development in southern China. The Ministry of Land and Resources has established a comprehensive shale gas exploration test area in northern Guizhou Province. Graptolite biostratigraphic biozone have been recognized in the Ordovician-Silurian Wufeng and Longamxi formations at well Anye 1 in the Anchang syncline in Zheng'an county of Guizhou province. These allow biostratigraphic subdivision correlation with well Jiaoye 1 which is productive of shale gas. WF2-LM5 graptolite zones of the Wufeng Formation and lower Longmaxi Formation in Zheng'an may be good reservoir of shale gas. LM5 graptolites zone of top black shale of the Longmaxi Formation is observed at the Baoshangcun section in the Anchang syncline, and this can be used to mark the top boundary of black shale in well Anye 1.
