原始有机质丰度的恢复及其意义

本文利用能反映有机质(碳)量随成熟度和有机质类型而变化的热模拟实验数据和松辽盆地泥岩岩体质量随埋深(成熟度)而变化的实际观测数据,通过逐步回归分析将原始有机碳(C~0)丰度定量地表述为不溶残碳(D_K)、有机质类型(KTI)和成熟度(R_0)的函数,达到了定量恢复原始有机质丰度的目的。在松辽盆地初步应用,效果比较理想,并可以近似地应用于其它盆地。

THE RECOVERY OF ORIGINAL ABUNDANCE OF ORGANIC MATTER AND ITS SIGNIFICANCE

: Using thermal simulating experimental data reflecting the changes of organic matter content with maturation and the type of organic matter and the measured data of shale bulk volume in Songliao basin varying with buried depth ( maturation ) , the richness of orignal organic carbon is quantitatively expressed as the function of insoluble residual organic carbon ( Ck ) , the type of organic matter ( KTI ) and its maturation ( Ro ) , obtaining recovery of the original abundance of organic matter quantitatively. The results are good after it was initially used in Songliao basin, and it can be approximately used in other basins.
