| 摘要: |
| 在建立台北凹陷西部层序地层格架的基础上,通过区域沉积背景分析,明确了台北凹陷西部沉积主控因素,分析了准层序组及体系域的叠置样式,划分了沉积体系类型。首次在研究区开展了以四级层序为单元的沉积体系展布特征及空间演化分析,为储盖层评价、生储盖组合分析、勘探层系优选和各类型油气藏区带评价奠定了基础。 |

| Abstract: |
| The present paper deals,on the basis of the sequence stratigraphic framework and sedimentary facies distribution,Xinjiang,with the main controlling factors,stacking patterns of parasequence sets and systems tracts,and types of sedimentary systems in the western part of the Taibei depression,Turpan-Hami Basin.The distribution and spatial evolution of the Jurassic-Plaeogne-Neogene sedimentary systems based on the fourth-order sequence boundary are ascertained,and thus have provided a basis for the assessment of the source-reservoir-seal associations,delineation of exploration targets,and evaluation of various oil and gas fields in the study area. |
