甘肃省页岩气资源潜力及勘查开发浅析

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。

POTENTIAL ANALYSIS,EXPLORATION AND DEVELOPMENT OF SHALE GAS RESOURCE IN GANSU

In recent years, China has issued lots of policies and specifications to promote the sustained, rapid and healthy development of the shale gas exploration and development. There are four suits of source rocks in Gansu as Permo-Carboniferous marine-terrigenous source rocks, upper Triassic terrigenous source rocks, middle and lower Jurassic terrigenous source rocks and lower cretaceous source rocks. The occurrences of shale gas and coal have some similarities, the shale in Wuteng, Danma, Ordos, Minhe and Chaoshui basin features high total organic carbon content （TOC）, high maturity （R0） and large thickness of the source rock, therefore, these basins have good resource potentials, we should start the phased exploration and development as soon as possible.
