Geochemical characteristics and source discrimination of deep permian oils from well xjc 1 in the southeastern junggar basin

Summary The Junggar Basin is one of the most important superimposed basins in southeastern China, characterized by multiple source rocks and hydrocarbons productive horizons. Well XJC1 is one of the recently drilled wells with deep commercial tight oil/gas (>4000m) discovered in the Perman Lucaogou Formation (P2l) in the southeast of the basin, which suggests a great petroleum potential in this relatively low-level exploration area. Oil-oil and Oil-source rock correlation showed that the P2l oil from the XJCJ well were sourced from the P2l argillutite, which have a high hydrocarbons generation potential with large scale and a relatively wide range of thermal maturity (low to high level). It suggests a great petroleum exploration potential about normal and unconventional hydrocarbon resources in the southeastern Junggar Basin. This study would be helpful for the further petroleum exploration and exploitation in the area.
