达连河油页岩含矿区位于黑龙江省依兰地区,该区是一个半地堑式断陷盆地。油页岩形成受到多重因素制约,构造上在靠近断裂F_2的煤和油页岩厚度较厚,随着湖盆沉积范围的扩大,表现了一种从湖平面逐渐向岸上上超的过程;高水位体系域浅湖一半深湖相和水进体系域湖泊一沼泽相形成不同成因类型油页岩;孢粉分析结果可知油页岩形成的气候总体呈现出气候温和、温度下降的发展趋势;而气候的波动影响了古生物的发育,降低了有机质生产能力,进而造成油页岩含油率低。
The Darunhe oil shale ore-bearing area is located in Yilan, Heilongjiang Province, a semi-graben rift basin. Oil shale formation is constrained by multiple factors. The thickness of coal and oil shale near the fault F 2 is thick. With the extension of the sedimentary range of the lake basin, it shows a process of going upwards from the lake level to the shore. The lacustrine facies lacustrine half of the lacustrine facies lacustrine facies and water system lacustrine-marsh facies formed different genetic types of oil shale. The results of sporopollen analysis indicated that the climate formed by the oil shale generally shows the trend of mild climate and temperature drop; Climate fluctuations affect the development of paleontology, reducing the organic matter production capacity, resulting in low oil shale oil rate.
