纹理属性分析方法在准噶尔盆地玛湖一区风城组沉积相划分中的应用

Application of Texture Attribute Analysis Method in Sedimentary Division of Fengcheng Formation in Mararea 1 of the Junggar Basin

摘要: 利用多种地震属性综合分析地震相已成为油气勘探中常用的方法，不同属性在不同区块的应用效果也存在一定的差异，因此需要针对不同研究区的具体情况进行属性优选。本次研究针对准噶尔盆地玛湖一区风城组，综合测井资料和地震资料，采用单属性和纹理属性分析方法，建立玛湖一区沉积相与地震相的对应关系，并探讨玛湖一区风城组地震相划分的最优属性。结果表明，纹理差异性属性和纹理熵属性对于玛湖一区沉积相划分具有较好的指导意义。

Abstract: The comprehensive analysis of seismic facies using multiple seismic attributes has become a commonly used method in oil and gas exploration. The application effects of different attributes in different blocks also vary, so it is necessary to optimize attributes based on the specific situation of different research areas. This study aims at Fengcheng Formation in Mararea 1 District of the Junggar Basin, and uses single attribute and texture attribute analysis methods to establish the corresponding relationship between sedimentary facies and seismic facies in Mararea 1 District by integrating logging data and seismic data, and discusses the optimal attributes of seismic facies division in Fengcheng Formation in Mararea 1 District. The results indicate that the texture difference attribute and texture entropy attribute have good guiding significance for the classification of sedimentary facies in the Mararea area.
