摘要
克拉玛依油田七区综合测井资料有限,在砾岩储层精细描述中,利用标准测井资料分析计算了砾岩储层物性的参数变化,利用标准测井视电阻率和岩心分析资料建立了储层岩性图版及电性标准,利用孔隙度分析资料和综合测井资料标定了标准测井自然电位减小系数及视电阻率值刻度,建立了区块标准测井储层评价及孔隙度、含油饱和度分析模型。而且标准测井分析模型孔隙度、含油饱和度平均绝对误差和相对误差均在储层描述工作允许范围内,从而解决了在缺乏综合测井资料时无法进行储层精细描述及参数标定的问题。
The 7th area of Karamay Oilfield has limited comprehensive logging data.In the process of conglomerate reservoir description,type log data is used to analyze and calculate petrophysical parameters;lithologic chart and electrical character standard are established by using core analysis data and apparent resistivity of type log;SP reduction factor and apparent resistivity are demarcated and an analytical model of porosity,oil saturation and reservoir evaluation is established by using porosity analysis data and comprehensive logging data.Contrasting with comprehensive well logging data,the mean absolute error and relative error of porosity and oil saturation of type log analytical model are within allowance of reservoir description.This offsets the defect that fine description of conglomerate reservoir can't be carried out because of the absence of comprehensive well logging data.
