从测井信息提取的地层胶结指数,更能反映储层孔隙流体性质的特征。本文提出的地层胶结指数法,引入了背景值和下限值概念,用它指示油气层,具有更高的分辨率和直观性。该方法还能够定量确定油气层含水饱和度及其有效厚度,并能控制测井数据处理质量。文中给出的应用实例表明,用地层胶结指数法指示砂岩油气层,获得了令人满意的效果。 The formation cementation index extracted from well logging information can better reflect the characteristics of reservoir pore fluid. In this paper, the formation cementation index method, the introduction of the background value and the concept of the lower limit, use it to indicate the reservoir, with higher resolution and intuitive. The method can also quantitatively determine the water vapor saturation and its effective thickness, and can control the logging data processing quality. The application examples given in this paper show that the sandstone reservoir is indicated by the formation cementation index method and satisfactory results are obtained.
