用地温测井资料快速预测二连盆地巴彦花群有机质热演化程度

A QUICK PREDICTION OF THERMAL EVOLUTION FOR ORGANICS IN BAYANHUA GROUP OF ERLIAN BASIN WITH THE APPLICATION OF GEOTHERMAL LOGGING DATA

本文用数学地质方法,建立了二连盆地巴彦花群实测地温资料的有机质热演化程度判别函数式。由这一实测今地温与有机质热演化程度的统计学对应关系,在生油评价之前,直接对有机质热演化程度作统计学预测,其判别预测结果与生油评价结果基本一致。

Using the methods of mathematical geology, a criminant function is devel-oped for the thermal evolution of organics from Bayanhua group , based on geothermal logging data. Before the estimation of petroleum generation , a direct statistic prediction for the thermal evolution of organics can be made on the basis of statistical correlation of geothermal loggings and the thermal evolution of organics. The results of the prediction are fundamentally consistent with those from the estimation of petrolenm generation.
