摘要
针对以孔隙度渗透率之间的指数关系为模型解释渗透率时精度不高的问题,提出了一套完整的动静态资料结合求取储层渗透率的方法。根据不同沉积微相渗流特征的差异性建立不同沉积微相渗透率的表达方式,并建立一个精度判别指标,对解释精度进行客观评价。利用试油试采的动态资料对静态解释结果进行动态校正,求出能够比较客观地反映出原始地层的渗流特点的动态渗透率。利用该方法在葡萄花油田三断块进行测井评价取得了良好的效果。
The conventional interpretation method for permeability, based on exponential relation between porosity and permeability, is not very accurate. So, proposed is an integrated method for permeability computation with dynamic and static data. A different sedimentary microfacies permeability expression is established according to differences in fluid percolation features of different sedimentary microfacies, and one new index for objectively evaluating permeability is given. Static data or core analysis data are used for accurate reservoir permeability computation, based on which the dynamic well test data are used to correct the above permeability that shows the fluid percolation features of virgin formation. The integrated interpretation method is successfully applied in the third block of Putaohua oilfield.
