| 摘 要： | 利用靖安油田延长 6组岩心分析资料和测井资料分析了靖安油田延长 6组中低孔隙性砂岩储层渗透性的影响因素。研究发现 ,油的有效渗透率与中低孔隙性储层的孔隙度、含水饱和度及泥质含量有关。应用多元线性回归分析法 ,建立了油的有效渗透率与储层孔隙度、标准化电阻率及自然电位的关系。应用统计关系式计算的有效渗透率与岩心分析的渗透率比较吻合。提出了应用工程测井值计算地层中油的有效渗透率的方法 ,同时还给出了储层含水饱和度与孔隙度和电阻率的关系式。

| Abstract: | The drilling core analysis data and well logging data of Jing'an oilfield are used to analyze the factors affecting low middle porous sandstone permeability. It is found that the oil effective permeability of low middle porous sandstone is related with the porosity, water saturation and shale volume of formation. The multivariate linear regression method is applid to establish the relation among effective permeability of oil and porosity, standard resistivity, standard spontaneous potential of formation. The effective oil permeability calculated by using the equation is consistent with the core analysis data. The method for calculating the reservoir permeability by using well logging data is presented. The relation of water saturation with porosity and resistivity of reservoir is also given. |
