近年来国家出台的一系列页岩气勘查开发的政策和规范,将促进我国页岩气资源勘探开发快速健康发展。甘肃省页岩气的烃源岩有4套,分别为石炭—二叠系海陆交互相烃源岩、上三叠统陆相烃源岩、中下侏罗统陆相烃源岩、下白垩统烃源岩,页岩气赋存与煤炭资源赋存关联度高,武腾盆地、旦马盆地、鄂尔多斯盆地、民和盆地、潮水盆地页岩有机碳含量(TOC)、热成熟度(R0)高,烃源岩厚度较大,具有较好的资源潜力,其页岩气勘查开发工作应分阶段尽早实施。
In recent years, a series of shale gas exploration and development policies and norms promulgated by the state will promote the rapid and healthy development of shale gas exploration and development in China. There are 4 sets of source rocks for shale gas in Gansu Province, which are Carboniferous Permian interbedded marine-continental source rock, Upper Triassic terrigenous source rock, Middle-Lower Jurassic continental source rock, Lower Cretaceous The correlations between the source rocks and shale gas occurrences of coal-bearing source rocks are high, and the TOC and T0 of shale in the Wuteng, Danma, Ordos, ) High, the source rock thickness is large, with good resource potential, and its shale gas exploration and development work should be implemented as soon as possible in stages.
