摘要： 在岩心分析的基础上, 建立“岩心刻度” 的测井定量解释模型以提高解释精度, 对于储集层描述和油气层评价具有重要意义。作者提出了建立模型前对岩心分析数据进行深度归位、数据匹配处理和对相应的测井曲线进行编辑、校正及进行标准化处理的方法。在此基础上, 建立起相应物性参数的测井解释模型,并从吐哈盆地丘陵油田的具体地质条件出发, 根据密度、中子孔隙度、声波测井曲线和自然伽马、自然伽马能谱曲线分别建立了孔隙度和泥质含量、渗透率解释模型;应用阿尔奇公式建立了砂岩储集层的饱和度解释模型。应用上述模型对丘陵油田的一些代表井进行了解释并与试油资料对比, 符合率达91.4 %.

Abstract: Based on core analysis, quanti tative log interpretation model with“core calibration"wasestablished, which canenhance accuracy of log interpretation, and is significant for reservoir description and oil/gas layer evaluation.This paper presented that depth homing of core analysis data, matching of data and interpretaing, correcting and standardization of log curves should be made before log interpretation model corresponding to physical parameter was established.According to geologic condition of Qiuling oilfield in Turpan-Hami basin, the models for porosity, shaliness and permeability were established based on density, neutron porosity, sonic logging curves and gamma ray and natural gamma ray spectrometry logging curves; the model for oil saturation interpretation of sandstone reservoir established with Archie formula.The practices of these models in Qiuling oilfield were correlated with available oil testing data, with accordance of 91.4 %.
