| 摘 要： | 美国5大页岩气盆地的勘探开发实践已证明,页岩气是一个很有潜力的非常规油气勘探新领域,资源丰富。页岩气与深盆气、煤层气一样属于"持续式"聚集的非常规天然气。在页岩气系统中,富含有机质的页岩既是系统的烃源层又是储层,也可能是盖层,各产层地质、地球化学条件迥异。页岩气存在形式主要以吸附气与游离气为主,形成机制可划分为生物成因、热成因及二者混合成因。页岩气的地质储量丰富,影响其成藏的因素主要有总有机碳、有机质类型和成熟度、产层孔隙度、地层压力及裂缝发育程度等,同时还要兼顾各参数之间的联系。四川盆地发育2套优质页岩(下寒武统筇竹寺组和下志留统龙马溪组),与美国5大页岩气盆地相比,具备形成裂缝性油气藏所需的优越的地质、地球化学条件,是一个天然气勘探开发值得高度重视的新领域。 |

| Abstract: | The history of exploration and production in North America has proved that shale gas is an unconventional resource with great exploration potential.Shale gas is a continuous accumulation of natural gas as well as deep-basin gas and coal-type gas.Shale with high organic matter not only acts as source rock,but also gas-producing layer and cap rock.The geological and geochemical conditions of shale gas formation are different in different gas layers.The shale gas mainly consists in absorbed and free gas genera... |
