黄县煤田第三纪有机岩中树脂体类型及成烃意义
THE RESINITE TYPES AND THEIR HYDROCARBON-FORMING SIGNIFICANCE IN TERTIARY ORGANIC SOURCE ROCKS IN HUANGXIAN COALFIELD
【摘要】 黄县煤田第三纪腐殖煤、藻烛煤、油页岩显微组分富含树脂体。根据产状和光学性质,树脂体划分为3种类型。GC/MS检测结果,饱和烃和芳烃馏分中存在大量的树脂生源的生物标志物,树脂体含量与总烃浓度,树脂体类型指数与烃转化率有良好的相关性。光学显微镜下,黄县煤田有机岩中发现有渗出沥青体和油珠。研究认为,树脂体是黄县煤田有机岩早期生烃的一种重要母质。
【Abstract】 Resinite is a rich n1aceral in Teriary humic coal,boghead-cannel coal and oil shale fromHuangxian Coalfield. According to the occurrence and opatical properties,resinite can be classified in-to three types.GC/MS identification results show that there are a large amout of biomarkers of resingenetic sources in saturate and aromatic hydrocarbon fractions. Arelationship existsbetween resinitecontent and total hydrocarbon,and so between resinite type index and hydrocarbon change rate, Ex-sudatinite and oil droplet are found in Huangxian organic source rocks under the microscopy。it is sug-gested that resinite is an important source matter of early hydrocarbon generation in organic sourcerocks from Huangxian Coalfield.
