THE APPLICATION OF SEDIMENTARY FACIES ANALYSES IN LITHOLOGIC POOL——TAKING TURPAN-HAMI BASIN JURASSIC SERIOUS AND CRETACEOUSSERIOUS AS EXAMPLES
沉积相分析在岩性油气藏勘探中的应用――以吐哈盆地胜北洼陷中侏罗统-白垩系为例

Turpan-Hami basin is a typical multicycle and multiplex basin, it has both the character of depression basin and that of rifted basin. The lithologic pool such as that developed in the actic region while the basin is rifting or in the glacis region while the basin is depressing all which can be found in this basin. Five kinds of sedimentary facies and thirteen sedimentary parfacies can be found in the Shengbei concave during the period of Jurassic series and Cretaceous series. Based on the research of succession of strata and the sedimentary parfacies, it shows that such as braided stream delta front submersed channel, alluvial middle fan rival chanel, fan delta front submersed channel and front-shallow lake beach and dam are mainly areas of lithologic pool developing.
