| 摘 要： | 对辽宁北部秀水盆地辽法D1井白垩系义县组上部烃源岩的有机质丰度、类型与成熟度及烃源岩厚度等特征分析表明，义县组湖相泥岩在盆地内分布广泛，厚度较大，为秀水盆地的主力烃源岩.义县组烃源岩TOC在1.37%~8.61%之间，平均值为3.70%，为中等-好的烃源岩，有机质类型为Ⅱ1-Ⅱ2型，Ro值较高，分布范围1.08~1.20，指示热演化达到成熟-生油高峰阶段，具有较好的资源潜力.

| Abstract: | The analysis on the organic matter abundance, type, maturity and thickness of the upper source rocks in Cretaceous Yixian Formation of LF-D1 well in Xiushui Basin, northern Liaoning Province, shows that the lacustrine mudstones serve as the main source rocks with wide distribution and large thickness. The TOC of source rocks is 1.37%-8.61%, averagely 3.70%, belonging to medium-good grade. The organic matter types are mainly II1-II2, with high Ro ranging from 1.08 to 1.20, which indicates the thermal evolution reaches mature to oil-generating peak stage with good resources potential. |
