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IH(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。
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,S 1 (the absorption hydrocarbon), S 2 ( the hydrocarbon of kerogen decomposition) and I H(Hydrogen Index, S 2/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.
