【摘要】 地震属性分析和砂体微相划分在以往的储层研究中都是分开进行的,彼此间没有很好地结合,从而降低了储层砂体微相研究的精度和准确性.作者在建立的层序地层格架的基础上,以莫8井区为例,对储层各种地震属性参数进行了提取和分析,并利用属性特征进行了J1s21砂体微相的研究和刻画,划分了有利含油气区.更多还原

【Abstract】 In the past,the analysis of seismic attributes and the division of sandbody microfacies are applied in the study of reservoirs separately and they are not combined with each other,which reduces the precision and the accuracy of the study of reservoir sandbody microfacies.In the study of the oil & gas reservoirs of Jurassic Sangonghe Formation in Mobei area of Jungar Basin,a variety of seismic attribute parameters of J1s21 sandbody in Mo-8 area are extracted and analyzed based on the establish of sequence stratigraphy framework.The microfacies of J1s21 sandbody are studied and described by means of the characters of the seismic attributes.As a result,the favorable exploration region in the wellblock is pointed for the future exploration work.更多还原
