| 摘 要： | 浙江省在区域大地构造位置上处于东亚大陆东南端,横跨扬子陆块区和武夷—云开造山系两大构造单元,在其杨子板块内具有储气优势层位的黑色页岩普遍发育,特别是分布于江绍拼合带西北的浙西地区,其寒武系荷塘组含烃页普遍发育,其中页岩气评价参数中的R0值为1.0%～4.0%,TOC值为0.74%～5.98%,有研究者认为在浙西地区TOC值可高达8%～10%,沉积厚度部分区域达600m,是浙江省最有利的页岩气选区。浙北长兴煤山盆地二叠系上统龙潭组C煤层下部发育的一套厚176～316m的砂质泥岩、页岩、细砂岩、中粗粒砂岩等互层岩系,富含有机质,也是页岩气的有利选区之一,另外浙江东海盆地的石油钻探资料证实,东海盆地也有煤层赋存,值得开展页岩气调查评价。

| Abstract: | Geotectonic position of the Zhejiang Province is at the southeast end of the East Asia continent,across the two large tectonic units of Yangtze landmass and Wuyi-Yunkai orogenic belt.In its Yangtze plate part has black shale with gas reservoir predominance generally developed,especially in the western Zhejiang area to the northwest of the Jiangshan-Shaoxing suture zone;there the Cambrian Hetang Formation hydrocarbon-bearing shale is widespread.In which,shale gas evaluation parameters Ro is 1.0%~4.0%,TOC val... |
