【摘要】：柴达木盆地具有丰富的油气资源,柴北缘、柴西、柴东三湖地区分别以侏罗系、古近系、新近系和第四系为主要勘探目的层。随着准噶尔盆地石炭系研究的进展和钻探的成功,石炭系已经成为中国西部地区重要的勘探层系。柴达木盆地的石炭系广泛发育,厚度较大,为一套碎屑岩与碳酸盐岩混合岩系,地质调查表明,石炭系为柴达木盆地一套潜在烃源岩。德令哈地区是柴达木盆地石炭系出露最多、地层层序最完整的地区。通过对德令哈及柴东地区MT勘探资料的处理解释和综合研究,对石炭系分布进行了深入研究,认为石炭系分布范围广、厚度大、构造稳定,其中欧龙布鲁克凸起油气成藏条件有利,是勘探的有利目标。
[Abstract]:The Qaidam Basin is rich in oil and gas resources. Jurassic Paleogene Neogene and Quaternary are the main exploration targets in the northern margin of Qaidam Basin western Qaixi and Sanhu area of Qaidong. With the development of Carboniferous research and the success of drilling in Junggar Basin, Carboniferous has become an important exploration strata in western China. The Carboniferous in Qaidam Basin is a series of clastic rocks and carbonate rocks. The geological investigation shows that Carboniferous is a set of potential source rocks in Qaidam Basin. Delingha area is the area with the most outcrop of Carboniferous system and the most complete stratigraphic sequence in Qaidam Basin. The distribution of Carboniferous in Delingha and Chaidong area is studied deeply through the processing interpretation and comprehensive study of MT exploration data. It is considered that Carboniferous distribution has a wide range, a large thickness and a stable structure. The Oulunbrook uplift is favorable for oil and gas accumulation and is a favorable target for exploration.
