松辽盆地大庆长垣四方台组可地浸砂岩铀成矿测井评价

摘要/Abstract

摘要： 为了研究孔隙度、渗透率、泥质等参数与砂岩型铀矿成矿的关系，本文对松辽盆地中央坳陷大庆长垣南部某区块四方台组底部砂岩进行分析。含铀矿砂岩具有高放射性，这使得测井曲线的密度值异常降低，自然伽马值异常升高。通过研究总结出利用升高的自然伽马曲线校正密度曲线的方法，以及利用其他不受放射性影响曲线重构自然伽马曲线的方法。与岩心的对比分析结果证明，校正后的密度曲线与重构后的自然伽马曲线较准确，密度曲线校正与自然伽马曲线重构解决了含铀砂岩利用测井曲线求取孔隙度、渗透率参数不准的问题。在准确求取测井参数的基础上，得到能展现砂体内部非均质性特点的物性空间展布并成图分析，进而得出本地区有利于铀成矿的物性条件：产生铀矿的砂体并不是孔渗性质最好的地方，也不是孔渗性质最差的地方，而是处于由高孔渗向低孔渗过渡的地方。

Abstract: In order to study the relationship between porosity, permeability and clay content and sandstone-type uranium mineralization, the authors analyzed the sandstone at the bottom of Sifangtai Formation in a block south of Daqing Placanticline in the central depression of Songliao basin. The uranium-bearing ore sandstone has high radioactivity, which makes the density value of the logging curve decrease and the natural gamma value rise abnormally. Through the research, this paper summarizes the method of correcting the density by using the increased natural gamma, and the method of reconstructing natural gamma by using other curves unaffected by radioactivity. Through the comparative analysis with the core, it is proved that the corrected density and the reconstructed natural gamma are more accurate. The problem that the parameters of porosity and permeability of uranium-bearing sandstone are calculated by logging curve is solved by the correction of density and the reconstruction of natural gamma. Based on the accurate calculation of the logging parameters, the spatial distribution and mapping analysis of the physical properties are obtained, which can show the characteristics of heterogeneity in sand body. It is concluded that the sand bodies producing uranium ore are not in the place with the best or the worst porosity and permeability, but in the place with the transition from high porosity and permeability to low porosity and permeability.

Key words: sandstone-type uranium deposit, Sifangtai Formation, curve correction, heterogeneity, ore-controlling theory, Songliao basin
