摘　　要：本文利用泥岩声波时差法和总声波时差法相结合,辅以镜质体反射率法,恢复了三江盆地白垩系—第三系地层剥蚀厚度。研究表明,三江盆地前进坳陷宝泉岭组剥蚀厚度具有东多西少,北多南少,富锦组剥蚀厚度则具有西多东少,南多北少的特点。滨参1井地区剥蚀作用使生烃处于停滞状态,对油气生成起破坏作用。In this paper, we calculate the erosion amount of Tertiary-Cretaceous Sanjiang Basin by mudstone and total acoustic time difference method and vitrini reflectance method. The result shows that the three methods fit well. It revealed that： Sanjiang Basin Baoquanling Formation erosion amount increase from Northeast Southwest, Fujin Formation erosion amount increase from Southwest to Northeast, In area of BC1, the erosion played a destroying role in the generation of hydrocarbon.
