摘要： 分析毛细管压力资料是评价储集层孔隙结构最直接有效的方法。连续获取储集层毛细管压力曲线一直是地质工作者追求的目标。针对储集层毛细管压力资料非常有限这一问题，以不同类型的岩心压汞资料分析为基础，提出了利用常规孔隙度、渗透率参数构造毛细管压力曲线的新方法，并建立了毛细管压力曲线的构造模型。该方法可以连续构造出储集层毛细管压力曲线，通过与岩心压汞毛细管压力资料的对比，验证了新方法的可靠性。

Abstract: It is the most direct and effective method to evaluate reservoir pore structure using capillary pressure data. Acquiring capillary pressure curves consecutively is the seeking target by geologists. In view of the finiteness of quantity of reservoir capillary pressure data, based on the analyses of various core mercury injection data, a new method for constructing capillary pressure curves using conventional porosity and permeability parameters is proposed and the relevant structural model is developed. The continuous capillary pressure curves can be constructed using this method. Comparison with core mercury injection capillary pressure data indicates the reliability of this method.

Key words: porosity, permeability, capillary pressure, construction, pore structure
