The Quality Evaluation and Hydrocarbon Generation and Expulsion Characteristics of Permian Lucaogou Formation Source Rocks in Jimusar Sag,Junggar Basin

摘要

1 Introduction The exploration practice in the Junggar Basin revealed that tight oils were self-generated and self-preserved in the Lucaogou formation,Jimusar sag.Because of the tight reservoir and frequent source-reservoir interbedding,the hydrocarbon supplying ability of source rock is the
