摘要：

根据烃源岩热解地化分析成果,应用所测岩样中有机碳TOC、吸附烃(S₁)、干酪根热解烃(S₂)含量及氢指数I_H(S₂/有机碳),对库车坳陷阳1井及吐格尔明露头煤系地层中的泥岩、碳质泥岩和煤岩从有机质丰度、有机质类型和成熟度三个方面进行了烃源岩分析评价,这三种岩石样品中各项生油岩指标绝大多数都达到了中—好烃源岩评价标准。指出库车坳陷侏罗系中—下统阿合—克孜勒努尔组为一套极具生烃潜力的煤系烃源岩。

关键词: 库车坳陷, 有机质丰度, 有机质类型, 有机质成熟度

Abstract:

According to the thermal decomposition achievement of mudstone, carbonaceous mudstone and coal samples, which are taken in the Jurassic coal-measure strata of Yang 1 well and Tougeerming outcrop in Kuqa depression, the organic matter abundance , type and maturation have been analysed with TOC,S1(the absorption hydrocarbon),S2( the hydrocarbon of kerogen decomposition) andIH(Hydrogen Index,S2/TOC).An absolute majority of samples have the features of high organic richness. The result of above analysis indicates that the Jurassic coal-measure strata of Kuqa depression is the coal -measure source rock of high hydrocarbon generating potential.

Key words: Kuqa depression, organic matter abundance, organic matter type, maturation of organic matter
