    摘要:

    优质烃源岩的分布是控制断陷盆地中油气分布的重要因素之一,对其准确的识别可以为下一步油气勘探提供有利的依据。本文采用丰富的测井资料,运用改进的ΔlogR模型,对乌尔逊及贝尔凹陷优质烃源岩进行识别,并对其分布进行预测。结果表明:改进后的ΔlogR模型应用简单客观,定量准确,在乌尔逊、贝尔凹陷应用效果好。通过计算得到的有机碳与实测有机碳间相关度R较高。在乌尔逊凹陷运用ΔlogR方法识别出的优质烃源岩主要分布于乌南和乌北两个区域,在贝尔凹陷主要分布于贝中、贝西和贝西南三个区域。

    Abstract:

    The distribution of high quality source rocks is one of the important factors which controls the distribution of oil and gas in rift basins,with its accurate identification ,we can provide the advantageous basis for the next step of oil-gas exploration. This paper adopts the rich logging data , using an improved ΔlogR model, to identify high-quality source rocks in Wuerxun and Beier Depression, and predict its distribution. It is proved that improved model is simple objective and more accurate in quantification as the result shows in Wuerxun and Beier Depression. The correlation coefficient R is high between Calculation organic carbon and Measured organic carbon.In Wuerxun depression high quality source rocks are mainly distributed in southern and northern part ,in Beier Depression mainly distributed in Central Western and Southwest three parts.
