摘要
裂缝性致密砂岩的解释模型是测井定量评价的基础。依据黄桥地区龙潭组地层裂缝性致密砂岩地质特点和孔隙空间的组成,利用三水模型分析了裂缝性致密砂岩的导电机理,提出了该地区的测井解释理论和方法,实现了组分孔隙度和饱和度的定量计算。应用表明,计算的三水导电组分孔隙度与核磁共振测井结果一致,测井解释结果与测试结果一致,认为该方法适用于该地区裂缝性致密砂岩的测井评价。
The interpretation model of the fractured tight sandstone is basis of logging evaluation and quantitative calculation. According to the geological features of the fractured tight sandstone, the composition of the pore space is analyzed. Based on three-water conductive model for logging interpretation method, the conductive mechanism is discussed and derived, the three-water interpretation method for fractured formation is proposed, which can achieve a quantitative calculation of the saturation. In Longtan formation of Huangqiao area, the three-water components calculated is good agreement with NMR logging interpretation results, and the test results indicate that this model is applicable for logging evaluation of the fractured tight sandstone.
