Examples
- Its applicability might be questioned on the grounds that carbonaceous shale is not known to occur near any of these deposits .
其实用性是有疑问的，因为还不知道在上述矿床附近存在着碳质片岩。 - Oil - source correlation studies show that the oil sample in well yi535 did not mainly derive from coals , but mainly originated from the coal measure mudstones and / or carbonaceous shales . the condensates in tiergen structure originated from coals with a later stage of maturation . the oils in yinan 2 well might originate from the coal measure mudstones with relative high maturity , which bear the same source as the oils in yi535 well but with different mature level
精细的油-岩直接对比发现：依535井原油并非典型的煤所生，它主要来自煤系泥岩和或炭质泥岩，而提尔根构造带的凝析油主要来自成熟晚期的煤；依南2井凝析油来自煤系泥岩，而不是三叠系湖相泥岩。 - With the tectonic uplift of the source area and the climate turning dry , the coal forming period was over , the fluvial system and fluvial - delta system became to play a major role . based on the study of former researchers and the theory of deep basin gas reservoir forming , the deep basin gas trap in the ordos basin is analyzed and is supposed to form in the ramp of the basin . it is supposed that the hydrocarbon of the deep basin gas trap is mainly composed of coal , carbonate and carbonaceous shale and with the " upper water seal " in the north of the study area the g
根据深盆气成藏理论和前人的研究成果，分析了深盆气藏的分布类型，认为鄂尔多斯盆地深盆气藏属于盆地斜坡成藏类型；认为深盆气的源岩以煤、炭质泥岩、暗色泥岩和碳酸盐岩为主；北部气水倒置、东部露头区有天然气逸出；气藏具有多重压力系统；成藏机理主要是气体动态的运移与聚集，稳定的构造背景有利于气藏的大面积保存。
