Based on the observation and study of a large number of cores and thin sections by cathodoluminescence and SEM, this paper expounds in detail the mechanism of the main diagenesis and its action mode and analyzes the diagenesis sequences and porosity evolution of the Permian Pingdiquan Formation in WucaiwanShishugou region of the eastern Junggar Basin.

通过对岩心、薄片、铸体薄片、扫描电镜等多种资料的综合研究,详细阐述了准噶尔盆地东部五彩湾-石树沟地区二叠系平地泉组储层主要成岩作用的形成机理和作用方式,分析了成岩序次和孔隙演化。

Associated with the study of lighter hydrocarbon constituent, carbon isotope, biomarker and inclusions, adopted the technique of oil source correlation on whole oil samples, it can be confirmed that the hydrocarbon source of viscous crude in Permian, in the east slope of Jimusaer depression, is Pingdiquan Formation mudstone; Carboniferous oil comes from Carboniferous source rock.

本论文根据轻烃、碳同位素、生物标志化合物等资料，运用全烃地球化学油源对比方法进行油源对比，得出吉木萨尔凹陷东斜坡区二叠系的稠油来自平地泉组泥岩，石炭系的稀油来自石炭系本身源岩；同时，根据地化资料研究了原油的成因，认为二叠系稠油是生物降解和成熟度较低共同作用的结果，石炭系的稀油存在轻组分散失现象；最后，综合构造、沉积、烃源岩和油藏地球化学资料，分析了吉木萨尔凹陷原油的成藏机制和模式。
