【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。更多还原

【Abstract】 In this paper,we calculate the erosion amount of Tertiary-Cretaceous in Sanjiang Basin by mudstone and total acoustic time difference method and vitrinite reflectance method.The result shows that the three methods fit well.It revealed that: in Sanjiang Basin Baoquanling Formation erosion amount increase from Northeast to Southwest,Fujin Formation erosion amount increase from Southwest to Northeast.In the area of BC1,the erosion played a destroying role in the generation of hydrocarbon.更多还原
