【摘要】 利用基于镜质体反射率恢复计算剥蚀量的Dow法及其修正法, 对松辽盆地深层主要剥蚀面的剥蚀量进行了评价。结果表明, 除鱼深 1井d/s剥蚀量可达 1 534 7m外, Dow法恢复所得的剥蚀厚度一般小于 730m; 与Dow法相比, 考虑了再埋藏影响的修正法评价所得深层的剥蚀量则高达 1 100~3 000m。初步分析表明, Dow法可能对应着剥蚀量下限值, 修正法则可能对应着剥蚀量上限值。更多还原

【Abstract】 This paper evaluates the denudation thickness on the denudation surface in the deep part of Songliao Basin using Dow method and its correction method basing on vitrinite reflectance restore calculation.The result shows that the denudation thickness obtained by Dow method is less than 1 100～3 000 m except Well Yushen 1 with the d/s denudation thickness of 1 534.7 m.The denudation thickness obtained by Dow method is less than 730 m.Comparing to this value, the deep denudation thickness obtained by the correction method considering the reburial effect is 1 100~3 000 m.The analysis shows that Dow method may correspond to the lower limit of the denudation thickness value,while the correction method may correspond to the upper value.更多还原
