| 摘 要： | 鄂尔多斯盆地三叠系延长组长7烃源岩是中生界油气的主要来源,研究其有机质丰度对评价该区烃源岩具有重要意义。通过采用ΔlogR法,将声波时差、电阻率和密度测井曲线与实验分析得到的烃源岩TOC值进行多元线性回归分析,进而获得烃源岩TOC的计算模型。经验证,该模型能准确反映长7烃源岩TOC的变化趋势,且计算简便,可广泛用于华池—庆阳地区各探井长7烃源岩的TOC恢复。 |
| 关 键 词： | 有机碳含量 测井评价 ΔlogR法 鄂尔多斯盆地 |

| Abstract: | Chang 7 source rocks of Triassic Yanchang Formation in Ordos Basin are the main resources for oil and gas of Mesozoic in Ordos Basin, so it is very important to study their organic matter abundance for the evaluation of the source rocks. By using A LogR technique, one TOC computational model can be obtained by using multi-linear regression analysis of the acoustic time logging curves, resistivity logging curves, density well logging curves and TOC of the source rocks from the experimental analysis. The result shows that the model can reflect the change trend of TOC of Chang 7 source rocks precisely. And the calculation is simple and convenient, so this model can be widely used in the recovery of TOC of Chang 7 source rocks in Huachi-Qingyang area. |
