Geochemical Characteristics of Mud Shale and Sedimentary Microfacies Research of Late Paleozoic in Southwestern Shandong Province
摘要
Abstract
As to study the sedimentary characteristics and environments of southwestern Shandong province could provide a basis for the assessment of source rocks, geochemical elements of LYC1 well sediment core is tested by high resolution XRF scanning method. 300 set of data of geochemical elements have been gained. By using petrol⁃ogy and sedimentary geochemical mehods, characteristics and sedimentary environment evolution of Luxi uplift in late Paleozoic period have been studied. It is showed that organic carbon contents of late Paleozoic shale which LYC1 well is the representative is high. Most of the hydrocarbon source rocks reached medium level and above, and kerogen is mainly Ⅲ type which is favorable for producing gases. Thermal evolution degree is in mature stage and has good potentiality of hydrocarbon generation. Late Paleozoic sedimentary environment presents an overall trend from marine facies to continental facies. It belongs to continental transitional facies. Geochemical index and charac⁃teristics of clay minerals have an apparent of sedimentary environment change trend.关键词
