| 摘 要： | 松辽盆地湖相泥岩地层中有机碳呈有规律的分布。在纵向上,特定的地层沉积单元常显示出底部有机碳含量高而向上含量逐渐减小的变化趋势。这种变化规律与相对湖平面的升降及沉积物的供给有关,并且可以在电阻率和声波时差叠覆曲线上以不同程度的幅度差表现出来。根据这种叠覆的测井曲线对松辽盆地英台地区嫩江组泥岩地层中的有机质丰度以及地层层序进行了分析。英台地区嫩江组一、二段泥岩地层以嫩一段和嫩二段下部地层的有机质丰度较高。从泥岩层序对比及测井曲线幅度差分析,该时期英台地区沉积物源来自于北部,其南部烃源岩有机质含量要高于北部。以嫩江组为主要烃源岩的黑帝庙油层的勘探也证实了这一点.

| Abstract: | The total organic carbon (TOC) of the mudstone formation in Songliao basin shows a regular distribution. Vertically, the high TOC value usually appears at base and decreases upwards in a given sediment unit. The regular change of TOC value as this is related to relative lake level change and sediment supply, and can be identified from the overlay log curves of sonic and resistance. Based on this method, it has been analyzed that the abundant of organic carbon and sequences of Nenjiang mudstone formation in Yingtai area, Songliao basin. The study show that the high content organic carbon appears at lower part of Nenjiang Formation, and the direction of sediment supply is from north to south. The content of organic carbon in source rock is higher in the south than north. Oil and gas exploration practice has proven that those results are true. |
