摘　　要：通过泥岩和泥岩顶底板加ＮａＣｌ的生排烃模拟，指出盐湖相未成熟或低成熟石油是沉积岩石中分散有机质经化学降解聚集的产物，并对早期成烃机制进行了探讨，对常用的烃源岩母质类型、成熟度等参数提出了新的认识。Based on the simulation study on the hydrocarbon generation and expulsion from mudstone samples with or without addition of NaCl on the top and bottom,it is suggested that the immature and low-maturity oil in saline lake facies rocks be resulted from the accumulation of dispersed organic matter in sedimentary rocks by chemical degradation.The mechanism of hydrocarbon generation at early stage is also discussed,and new ideas on the maturity and common types of source materials are put forward.
