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
