通过分析岩心、测井及分析化验等资料,对风城油田重37井区齐二段储层四性关系进行研究,明确了该区储层岩性、电性、物性及含油性之间的关系特征。研究结果表明齐二段储层岩性以中细砂岩为主、其次为含砾砂岩。该区储层具有高孔高渗的特点,物性越好含油级别越高。通过建立各储层参数测井解释模型并结合试油资料,确定了储层物性下限标准:电阻率≥16Ω?m,孔隙度≥26%,含油饱和度≥50%。为储层精细刻画评价奠定坚实基础,为指导生产调控提供依据,对提高油田生产效果具有重要的指导意义。
Through the analysis of core, well logging and analytical laboratory data, the quaternary relationship of Qi 2 Member Reservoir of Chong 37 well in Fengcheng Oilfield was studied, and the relationship between lithology, electrical property, physical property and oil content of reservoir in this area was clarified Relationship characteristics. The results show that the reservoir lithology of Qi 2 Member is dominated by medium and fine sandstone, followed by pebbly sandstone. The reservoir has the characteristics of high porosity and permeability, the better the physical properties of the higher oil level. Through the establishment of well logging interpretation model of each reservoir parameter and the combination of test oil data, the lower limit of physical property of reservoir is determined: resistivity≥16Ω? M, porosity≥26%, oil saturation≥50%. It lays a solid foundation for the fine characterization of reservoir evaluation and provides the basis for guiding the production regulation and control. It has important guiding significance for improving the production effect of oilfield.
