摘要
在对吐哈盆地台北凹陷西缘层序地层格架建立的基础上,以区域沉积背景分析为先导,在明确台北凹陷西缘沉积主控因素的前提下,分析准层序组及体系域的叠置样式,划分沉积体系类型,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,为在研究区开展储、盖层评价、生储盖层组合分析、勘探层系优选和各类型油气藏区带评价奠定了基础。
On the basis of sequence division of strata and taking the depositional setting into account, the principal control factor of the western Taibei sag can be ascertained. The distribution and evolution of sedimentary facies in the western Taibei sag is analyzed after dividing the type of depositional system and considering the stack style of sub-succession of strata. The study paves the way for the research such as the evaluation of reservoir and cap rocks, the analysis of source-reservoir-cap association, the choice of exploration beds, and the evaluation of all kinds of oil-gas fields.
