摘要
对柴达木盆地大煤沟侏罗系剖面进行了高分辨率层序地层分析 ,并探讨了聚煤作用与高分辨率层序的关系 .在相类型、相组合和相序综合分析的基础上 ,运用高分辨率层序地层学的基本理论和方法 ,将柴达木盆地大煤沟侏罗系剖面划分为 7个中期旋回 (准层序组 )和 1 0～ 1 2个短期旋回(准层序 ) .以基准面升降为驱动机制的高分辨率层序地层学可提高地层划分精度 .它是陆相层序地层、储层对比与预测的有效手段 .
The Jurassic section in Dameigou, Chaidamu Basin is analyzed by high resolution sequence stratigraphy and the relationship between coal accumulation and high resolution sequence is also discussed. On the basis of the analysis of facies type, facies association and facies series, the Jurassic section is divided into 7 middle term cycles and 10~12 short term cycles by using the theory and method of high resolution sequence stratigraphy. High resolution sequence stratigraphy, which is based on the control of baselevel rising and falling, can improve the precision of stratigraphic division, and it is an effective way to research continental sequence stratigraphy and predict correlation of reservoirs.
