| 摘 要： | 近年来,结合丰富的地球物理信息和地球化学实验数据来研究烃源岩,可有效克服常规岩样分析资料连续性差、成本高的难题,且获得了广泛的应用,但在实际应用过程中发现,其准确性并非很高。文中以辽河西部凹陷为例,结合取心井SG1的烃源岩地球化学和测井资料,重点对比了不同成熟度范围的烃源岩的测井响应差异。通过讨论影响烃源岩TOC测井计算方法准确性的各种因素,对比了最小二乘法与ΔlgR方法的优缺点,认为最小二乘法拟合公式的3个常数(A,B,C)包含了多种影响计算结果的因素,因此,最小二乘法更能反映烃源岩层TOC的变化,且在应用时具有较强的可操作性。

| Abstract: | In recent years, combining abundant geophysical information with geochemical experimental data to study source rocks can effectively overcome the weakness of poor continuity and high costs in conventional formation sample analysis, so it is widely applied. However, it is not found with high accuracy in the practical application. Taking Western Sag in Liaohe Basin as an example, based on the geochemical and well logging data of source rocks in SG1 well, the log responses of source rocks with different maturi... |
