Characteristics of Permian hydrocarbon source rocks from Well ZK0-1, western Ejin Banner, Inner Mongolia and their significance

More Information
  • As drill holes are rare in the Paleozoic target strata, cores of drill holes are very limited. In this paper, the authors analyzed the stratigraphic lithologic association characteristics revealed by Well ZK0-1 of the Lubeiup lifted zone in western Yingen-Ejin Banner basin. Based on an analysis of previous achievements, the authors systematically collected hydrocarbon source rocks from the Lower Permian dark-colored mudstone sections. The orogenic geochemical characteristics including organic abundance, kerogen types and organic matter maturity were analyzed, and the results indicate that high quality hydrocarbon source rocks are characterized by the Permian thick hydrocarbon source rocks (>43m thick per bed), high organic abundance (average TOC 3.1%), kerogen type Ⅱ and low maturity maturity stage. In addition, the weathering effects on hydrocarbon source evaluation factors were discussed on the basis of a comparative study of the geochemical characteristics of the Permian cores and outcrop samples.
