孔渗模型的研究是储层特征及其评价的重要基础,孔隙度和渗透率是孔渗模型的重要参数,此文首先利用体积模型建立实测孔隙度与测井参数之间的关系,得出了研究区长6储层的孔隙度解释模型,再根据渗透率与孔隙度之间的线性相关关系建立渗透率解释模型,从而得到考虑了碳酸盐含量影响的孔渗模型。建立的这种模型的精确度达到了本区块评价标准,可以指导油田实际生产。

Model construction of porosity and permeability plays an important foundation for evaluation of reservoir characteristics. In this paper, firstly, we use the volume model to establish the relationship between the measured porosity and logging parameters, and obtain the porosity interpretation model for Chang 6 reservoir. Then, according to the linear relationships between the permeability and porosity, we establish the permeability interpretation model, obtain the porosity and permeability model considering the influence of carbonate content. The accuracy of this model has reached the evaluation criteria for the study area, and can be used to guide the actual oil production.
