Organic Geochemical Features of Permian Source Rock from Lucaogou Formation in Ji 174 Well of Jimsar Depression

According to the organic geochemical analyses on Permian source rocks from Lucaogou formation in Ji174 well of Jimsar depression in Junggar Basin,the organic matter abundance,type and maturity are revealed,which leads to a discussion on the hydrocarbon generative potential. The results show that the organic matter abundance has reached the standard of good to best quality source rocks. The kerogen is mainly type II,and the organic matter has gone into mature stage. Thus,the Permian mudstones from Lucaogou formation in Ji 174 well are a set of high-quality source rocks with high hydrocarbon generative potential,they are the providers of Permian dense oils in Lucaogou formation.
