摘要

岩石渗透率是衡量孔隙介质允许流体流动和产出能力的重要参数,反映了油、气、水被采出的难易程度,是控制储层质量和油气井产能的决定性因素,是确定有效储层物性下限的重要参数之一。其准确性直接关系到储层非均质性分析、产能的确定以及开发方案设计和调整,合理的储层评价必须以渗透率为基础。对南海东部海域纯油气藏进行研究,根据取心分析和常规测井资料,采用交会图、统计分析方法,分析测井曲线的物性响应特征。采用流动单元分类方法对储层分类及其划分。建立绝对渗透率与测井资料的多元回归模型,基于流动单元划分的渗透率计算方法,利用核磁共振谱的渗透率计算方法。并将这3种渗透率计算模型进行对比分析。
        Rock permeability is an important parameter to measure the ability of porous media to allow fluid flow and output in reflecting the difficulty of oil, gas and water being produced. It is the decisive factor in controlling reservoir quality and oil and gas well productivity. It is one of the important parameters to determine the lower limit of effective reservoir properties. Its accuracy is directly related to reservoir heterogeneity analysis, capacity determination, development design and adjustment. Reasonable reservoir evaluation must be based on permeability. This paper discusses about the pure oil and gas reservoirs in the eastern South China Sea on coring analysis and conventional logging data. The physical response characteristics of the logging curve are analyzed by using the intersection graph and statistical method, including a classification of reservoirs in using flow cell classification methods. Established in a multiple regression model of absolute permeability and log data, we have made a permeability calculation method based on flow unit division. A method for calculating the permeability of a nuclear magnetic resonance spectrum is also used. Three permeability calculation models were compared and analyzed.
