中国矿业大学 资源与地球科学学院 地质系 杨兆彪 老师 Int J Coal Geol 研究成果
2019/6/4
近日，我院地质系杨兆彪老师在著名期刊International Journal of Coal Geology发表了多煤层煤层气井产出水地球化学响应的最新研究成果。该研究以贵州松河煤层气井组为例，主要基于产出水常规离子、氢氧同位素，溶解无机碳(DIC)稳定同位素为分析对象，探讨了多煤层煤层气井组形成井间干扰时和层间干扰时的地球化学响应特征及其产能意义。研究发现：形成井间干扰过程中，动液面变化与产出...
中国科学院地质与地球物理研究所兰州油气资源研究中心李靖-International Journal of Coal Geology: 页岩与干酪根在60MPa高压条件下的甲烷吸附特征（图）
中国科学院地质与地球物理研究所兰州油气资源研究中心 李靖 页岩 干酪根 60MPa 高压条件 甲烷吸附特征
2018/7/25
吸附气是页岩气的重要赋存形式，其在页岩气中所占的比例可达80%。页岩的气体吸附性能直接决定了页岩层段中吸附气的含量，是页岩气资源潜力评价的重要参数，也是近年来的研究热点。四川盆地是我国页岩气资源最为丰富的区域，目前已在其古生界地层中发现涪陵、长宁—威远等多个页岩气田，页岩气产量也稳步攀升。四川盆地古生界页岩具有埋深大、流体压力系数高的特点，页岩层段中气体压力可达60MPa。然而目前已发表的针对四川...
