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

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。

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.
