摘要

摘要: 在沉积有机相接近的前提条件下，重排藿烷的相对丰度与热成熟度密切相关。选用鄂尔多斯盆地低熟(R_o为0.58%)富有机质(总有机碳含量为3.87%)泥页岩进行生排烃热模拟实验，通过气相色谱—质谱(GC-MS)对排出油和滞留油中17α(H)-重排藿类化合物进行了检测与分析，并结合热模拟残余岩样的实测镜质体随机反射率(R_o)界定了17α(H)-重排藿烷参数作为成熟度指标的适用范围。结果表明，无论在排出油还是滞留油中，参数C₂₉*/(C₂₉*+C₂₉H)和C₃₀*/(C₃₀*+C₃₀H)呈现出类似的三段式变化特征，均随实验温度的升高先降低后升高最后降低，表明两个参数可能是较好的油源对比指标。在325 ℃之前，即R_o＜1.01%时，参数变化幅度均不明显；但在325~385 ℃之间，两个参数均随温度的升高呈现显著的上升趋势，表明在有机质成熟中期—高成熟早期阶段(1.01%＜R_o＜1.48%)两个参数均可作为有效的成熟度指标。

Abstract: With the comparable sedimentary organic phase, the relative abundance of rearranged hopanes can be correlated to maturity degree. By the approach of artificial maturation experiments of low-maturity (R_o=0.58%) and organic-rich (TOC=3.87%) mud shale collected from the Ordos Basin, 17α(H)-diahopanes in expelled and retained oils were examined by gas chromatography-mass spectrometry (GC-MS). The thermal evolution characteristics of parameters related to 17α(H)-diahopane were discussed, and the maturity range of these parameters as maturity indicators was proposed, combined with the random mean vitrinite reflectance (R_o) of maturated rock samples of each step of pyrolysis. Results show that the parameters of C₂₉*/(C₂₉*+C₂₉H) and C₃₀*/(C₃₀*+C₃₀H) have similar three-stage variations. As experimental temperature increased, the values of the two parameters decreased firstly, then increased and finally decreased again, indicating that they may be good indicators for oil-source correlation. Before 325 ℃, i.e. R_o < 1.01%, both parameters showed insignificant changes. However, they both showed an obvious upward trend with increasing temperature from 325 to 385 ℃, indicating that they were valid indicators for maturity from the moderate to the early stages of high maturity (i.e. 1.01% < R_o < 1.48%).
