本文分析研究了沧东凹陷孔二段烃源岩的展布特征及生油指标，明确了孔二段烃源岩的分布范围及其“有机质类型好、优质烃源岩发育、埋藏深度大、演化程度高”等特点，建立的成烃演化模式对油气勘探具有重要的指导意义。在此基础上，通过对油气成藏特征与控藏机制的研究，明确了孔二段致密油“源储一体，叠加连片”的“连续性”油气富集模式。

This paper investigates the features of hydrocarbon source rock distribution and index of generating oil in Kong-II section, Cangdong Sag to figure out the distribution range of hydrocarbon source rocks and the characteristics of being buried deeply,high degree of evolution,good organic matter,and optimum source rock development.The Hydrocarbon evolution pattern is established for guidance of exploration.It suggests that the thick oil reservoir in this area belongs to continuous hydrocarbon enrichment model of integration of overlaid source and reservoir based on studies of the hydrocarbon accumulation and mechanism of reservoir controlling.
