摘要
扶余油田中区泉四段主要为三角洲相沉积,储层岩性以粉砂岩和细砂岩为主。通过研究区取心井四性关系研究,采用岩心分析、录井及试油资料刻度测井的方法,建立了研究区的泥质体积分数、孔隙度、渗透率和原始含油饱和度测井解释模型。通过取心井岩心分析数据与模型解释数据对比,验证了解释模型的正确性,为进行测井资料二次数字处理,实现储层参数由取心井到非取心井的最佳定量求取提供了可靠依据。同时进行了油层有效厚度下限的多维研究,准确界定了泉四段油层的岩性、含油性、物性和电性下限标准,为该油田的进一步开发提供依据。
In the central area of Fuyu Oilfield, K1q4 reservoir is mainly the delta facies and the reservoir lithology is dominated by sihstone and fine sandstone. Based on the four-property relation study for coring wells, the log interpretation models for shale content, porosity, permeability and original oil saturation within the working area are established through utilizing core analysis data, logging and testing data to calibrate the logging interpretation. Besides, compared core analysis data of coring well with model interpreting data, the models are proved with high accuracy, which provides a reliable quantitative basis for the secondary digital processing of logging data and realizing the optimal quantification of reservoir parameters from coring wells to non-coring wells. Meanwhile, through multi-dimensional research on lower limitation of net pay thickness of the oil reservoir, lower limitations of lithology, oil-bearing property, physical property and electrical property are precisely defined, providing a basis for further development of the oiffield.
