| 摘 要： | 研究了我国西北地区侏罗系含煤盆地沉积环境、烃源岩厚度和地球化学指标等特征,并与世界若干著名的煤成油盆地进行对比,根据含煤建造层序地层学特征、含煤岩系及泥岩厚度、生油岩系在地史期间和现今上覆地层厚度等方面的特征,对我国西北地区侏罗系含煤盆地前期煤成油勘探提出了三项地质评价指标:常规地球化学评价指标;盆地沉积厚度、构造演化及烃源岩成熟度指标;盆地生油岩层序地层学指标.

| Abstract: | The sedimentary environment, source thickness and geochemical characteristics in the Jurassic coal-bearing basin, northwestern China were examined and compared with several most famous coal-formed oil-bearing basins in the world. This paper puts forward three indicators of geologic evaluation for preliminary coal-formed oil prospecting in the Jurassic coal-bearing basin, northwestern China, namely, conventional geochemical evaluation indicator, indicators for sedimentary thickness, structural evolution and source maturity, and sequence stratigraphic indicator of source rock in the basin, based on sequence stratigraphy of coal-bearing formation, thickness of coal measure and mudstone, source thickness in geologic history, and present overlying formation thickness. |
