摘　　要：贝16井含油地层剖面自下而上划分两个孢粉组合：桫椤孢-脊缝孢-罗汉松粉（Cyathidites-Biretisporites-Podocarpidites）组合和无突肋纹孢-紫萁孢-巴彦花孢（Cicatricosisporites-Osmundacidites-Bayanhuasporites）组合。依据岩性、电性、古生物、同位素和伊利石结晶度（饱和）等综合研究,将贝16井含油地层自下而上划分为兴安岭群塔木兰沟组、上库力组（缺失伊利克得组）,扎赉诺尔群铜钵庙组。前人划归为布达特群的1807.5-2030.0 m井段岩石应划归为塔木兰沟组;塔木兰沟组的地质时代为早白垩世最早期,不排除下部有部分地层属晚侏罗世的可能;上库力组的地质时代为早白垩世早期,可能为早白垩世Berriasian中晚期-Valanginian早中期。The section of oil-bearing strata of well Bei 16 consist of two sporopollen assemblages： Cyathidites-Biretisporites -Podocarpidites , and Cicatricosisporites-Osmundacidites -Bayanhuasporites. According to the synthetic study of the authors, the above-mentioned strata are divided into Tamulangou Formation and Shangkuli Formation of the Xing＇ anling Group （hiatus of Yilikede Formation）, Tongbomiao Formation of Zhalainuoer Group from bottom to up. The rocks in depth of 1 807.5- 2 030.0 m that were regarded as Budate Group, are belonging to the Tamulangou Formation; the Tamulangou Formation is considered early Early Cretaceous in age, and can not be ruled out the possibility that the lowest part of the strata belong to Upper Jurassic; while the Shangkuli Formation is the earlier Early Cretaceous, also may be the middle-late Berriasian to earlymiddle Valanginian.
