摘　　要：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。古近系达连河组为一个完整的三级层序，油页岩形成于水进体系域和高水位体系域发育时期。油页岩沉积相类型为半深湖相沉积。与泥炭沼泽相煤层伴生，为煤层的顶板，含油率为3．75％～8．37％。有较高的开采价值。煤层顶部发育的巨厚湖相劣质油页岩，分布广，层位稳定，含油率〈3．5％。研究区油页岩成因类型为混合型和腐殖型。根据油页岩工业划分标准，达连河油页岩属于中灰分、低含油率的油页岩。The Dalianhe oil shale mine lies in the Yilan area of Heilongjiang Province,which is a half-graben faulted basin.The Paleogene Dalianhe Formation makes up a complete succession of the 3rd order.The oil shales were developed during transgression and highstand systems tract,and were developed in sub-deep lacustrine environments.The oil shales are associated with and lie on a coal layer of turfy-swampy facies.Their oil yield is between 3.75% and 8.37%.This high quality oil shales are of better exploitation value.Bad lacustrine oil shales were developed on the upper part of coal layers with extensive extension and stable horizon and their oil yield is less than 3.5%.The genetic types of oil shales in the area under research are of humus and mixed type.According to the industrial division criterion of the oil shale,the oil shales of the Dalianhe Formation belonged to the middle oil yield with low-ash.
