河北省页岩分布及页岩气前景

Shale Distribution in Hebei Province and Shale Gas Prospect

页岩气作为非常规清洁能源,已正式进入我国能源战略视野。河北省在漫长的地质历史时期,广泛发育6套黑色页岩岩系:中上元古界洪水庄组和下马岭组、古生界石炭二叠系太原组和山西组、新生界古近系孔店组和沙河街组。岩相分别为海相、海陆交互相、湖相暗色泥页岩。其中,元古界页岩主要赋存于燕山以北,古生代与新生代页岩主要发育于冀东南。它们不仅具有分布范围广,埋深适中,是页岩气发育有利层位,具有页岩气资源勘探前景,其勘探开发将对于缓解我省能源危机和环境污染具有重要意义。

As an unconventional clean energy, the shale gas has played an important role in energy strategic vision of China. During the long geologic history have widely developed 6 sets of black shale rock series, including middle and upper Proterozoic Hongshuizhuang and Xiamaling formations, Paleozoic Permo-Carboniferous Taiyuan and Shanxi formations, Cenozoic Paleogene Kongdian and Shahejie formations. The lithofacies of dark shale have marine facies, alternating marine-terrestrial facies and lacustrine facies. In which, Proterozoic shale is mainly distributed to the north of Yanshan Mts., Paleozoic and Cenozoic shale mainly distributed in the southeastern Hebei Province. They have not only features of wide spread, medium buried depth, but also favorable horizons to form shale gas. Thus they have prospects of shale gas resource exploration and exploitation with significance to relieve energy dilemma and pollution issue in the province.
