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914%
On the basis of core analysis, it is very important for reservoir description and reservoir evaluation to set up a logging quantitative interpretation model of “core scale” to improve the interpretation accuracy. The author proposed a method of deep homing, data matching, and editing, correcting and standardizing the corresponding core logging data before establishing the model. On this basis, the log interpretation model of corresponding physical parameters is established. Based on the specific geologic conditions of hilly oilfields in Turpan-Hami basin, according to the density, neutron porosity, acoustic logging curves and natural gamma ray, natural gamma ray energy Spectral curves were established porosity and permeability and shale content, permeability model; Archie formula was established by the sandstone reservoir saturation interpretation model. Applying the above model to explain some representative wells in the hilly oilfield and comparing them with the test oil data, the coincidence rate reaches 914%
