deleveling
Examples
- Discussion about base - level changes in the analysis of high - resolution sequence stratigraphy
高分辨率层序地层分析中基准面变化的讨论 - This paper provides a review of the recent development of the research on fluvial incision from dynamical mechanism , physical erosion processes , influence of external variables , dealing with tectonics , climate and base - level change , and possibility of distinguishing their influences
文章从动力学机制、物理侵蚀过程、三大外来变量构造、气候和基准面变化的影响，以及区分这些变量影响的可能性等方面，对流水下切研究的最新进展予以评述。 - After have systematically studied sequence stratigraphy of chagan depression , a analysis method of high precision sequence stratigraphic framework in fault - depressed lacustrine basin . the core of the establishing framework is exploration - significant identify of sequence , division of 2 , 3 , 4 , 5 grades sequence and analysis of base - level based on lithologic log or well - logging , high - resolution seismic inversion constrained to well data . then using the results of 2d seismic data , and interpret sequence to enhance the precision of interpretation
断陷盆地高精度层序地层格架建立的核心是用钻/测井和井约束条件下的高分辨率储层横向预测剖面等高分辨率资料进行具有勘探意义的二、三、四和五级层序的界面识别、层序划分和基准面变化分析，在此基础上标定常规地震剖面，进行区域层序地层分析，达到提高层序地层解释精度的目的。 - The further study shows that the sandstones at the bottom of the lower ganchaigou formation , which is a tr lithostratigraphic unit , were deposited in different stages of base level cycle , and they are not chronostratigraphic unit . so , to identify different sequences , especially high order sequences in analysis of terrestrial stratigraphic sequences , the sequence distribution feature must be fully consided . this view has practical significance for recognizing forming , evolution and filling history of qaidam baisn correctly , and has both theorical and practical meaning for directing further oil exploration
研究还表明，传统岩石地层单位中下干柴沟组底部的砂岩代表了基准面变化旋回不同阶段沉积的产物，它们属于不同的成因单位，也非等时地层单位，因此，在进行陆相层序地层分析时，各级层序尤其是高级层序的识别要充分考虑面上的层序展布特点，这一观点对正确认识柴达木盆地的形成演化和沉积充填历史，指导今后的勘探具有一定的理论和实际意义。 - And it is also possible to analyze the reservoir property in reservoir framework . taking the reservoir of zonation 6 - 10 in s32 of pucheng oil field in henan province as an example , we founded the detailed reservoir stratigraphic framework through base - level correlation . in the strata frame , sediment distribution and its development are discussed based on sediment volume partitioning and facies differentiation analysis
依据基准面变化中的过程?沉积响应，分析沉积过程中沉积物体积分配及与其相伴生的相分异，进行等时地层对比，建立精细地层格架，预测储层空间展布及其非均质性的思路为储层精细描述提供了新的方向。
