高频层序地层单元厚度特征平面刻画方法——以白音查干凹陷X4井区为例

Portrayal methods of High-frequency Cycle Stratigraphic Units Planar Features——With X4 Well In Baiyinchagan Sag as an Example

应用层序地层学理论建立精确的时间与空间格架是沉积盆地分析的重要步骤,也是油气勘探的重要手段。工作人员对三级层序内部的高频旋回地层单元时遇到地层刻画不准的问题进行了研究,提出了一种新的方法来对高频旋回进行平面刻画。通过这种新方法实现了对三级层序内部的高频旋回的精确刻画。

Apply sequence stratigraphy theory to establish accurate time and space frame is an important step in sedimentary basin analysis, and also an important means of oil and gas exploration. The problem of inaccurate stratigraphic depicts encountered by high-frequency cyclic stratigraphic unit of internal three order sequence are studied by staff, a new method is proposed for plane characterization of high frequency cycle. Accurate characterization of high frequency cycle of the internal three order sequence has achieved through this new method.
