Based on the detailed observations��systematic samplings��organic geochemical analysis of the core of Well SZK01 in Jinyang Basin��the types of sedimentary facies and organic characteristics of Lower Jurassic Beipiao Formation of the well were studied�� The lacustrine facies was the main sedimentary facies identified in Well SZK01��and showed the changeable process from shore- shallow to semi- deep then to shore- shallow lake sedimentary subfacies in ascending order�� The change trend revealed that the sedimentary water body went through a stage from shallow to deep in depth��and then from deep to shallow later during the Beipiao Formation stage in Jinyang Basin�� The hydrocarbon source rocks of Beipiao Formation in Well SZK01 were mainly ranked on poor- medium level��and its organic abundance increased firstly and then decreased from the bottom up��in general�� The types of the organic matter were mainly ��- type and �� 2 - type�� which were mainly based on terrestrial organic matter input�� The thermal evolution of the organic matter was in high- over maturation stage��
