Title: Research of geochemical characteristics of Carboniferous source rocks in Junggar Basin
Abstract: The abundance,the types and the maturity of organic matter of Carboniferous source rocks in Junggar Basin are discussed,and the types of organic matter are determined by comprehensive geochemical indexes.It is shown that,the abundance of the organic matter is high,and it is higher in upper Carboniferous than in lower Carboniferous,and that in lower Carboniferous,the main type of organic matter is Ⅱ1 type,which is beneficial to the generation of mature oil and gas and condensate oil in higher maturity;in upper Carboniferous,the main type of organic matter isⅡ2 type and Ⅲtype,which is beneficial to gas generation.The few signs of geochemical characteristics of the Carboniferous source rocks are that the carbon isotope is heavy,there is not β-carotane in saturated hydrocarbon chromatogram,and the regular steranes show V shaped distribution with the significant advantage of sterane C27.
