基于高分辨率层序地层学的测井曲线小波分析模型

以高分辨率层序地层学为指导，以中期基准面上升半旋回和下降半旋回为基本的研究单元，建立其理想的层序地层模型和相应的测井曲线模型，通过Morlet小波对测井曲线模型进行分析，建立中期基准面旋回的小波分析模型，分析小波模型对不同基准面旋回的响应特征。然后以由不同样式中期基准面旋回叠加而成的长期基准面上升半旋回、下降半旋回为研究对象，建立其理想的层序地层模型和测井曲线模型，并利用Morlet小波对测井曲线模型进行分析，建立不同样式长期基准面旋回的小波分析模型，分析小波模型对长期基准面旋回及其内部中期基准面旋回单元、旋回界面的响应特征。史134井实例分析表明，不同样式的基准面旋回的小波分析模型能够有效地应用于层序单元及层序界面的识别和划分，对层序地层学的研究起到较好的指导意义。

Wavelet Analysis Models Based on High Resolution Sequence Stratigraphy

Based on high-resolution sequence stratigraphy,with medium-term base level rising half-cycle and falling half-cycle as basic research units,ideal sequence stratigraphy models and log curve models of them are set up.Wavelet analysis models are established on log curve models by the Morlet wavelets,and their response to different base level cycles are analyzed.Then,with long-term base level rising half-cycle and falling half-cycle as research units,which are stacked by various medium-term base level cycle,ideal sequence stratigraphy models and log curve models of them are set up.Wavelet analysis models are established and wavelet models response to the long-term base level cycle,base level cycle surface and its subordinate cycle units are analyzed.An example of well Shi 134 shows that wavelet analysis models of different types of base level cycles can be used to recognize and divide the sequence boundary and the sequence units.Wavelet analysis models can provide a meaningful guide to the research of sequence stratigraphy.
