| 摘 要： | 目前,我国处于开发中后期的油田平均产水率高达80%以上.因此对产层进行评价,确定地层动态渗透率等参数及剩余油的平面分布,由此研究其特点具有十分重要的意义.在储层径向流动方程分析的基础上,研究了储层渗透率与产液量/吸水量和油并内流压变化等生产测井资料之间的关系,提出了利用油田生产测井资料估算各产层的动态渗透率的方法.该方法不需关井,计算过程相对简单、可以节约成本,还可以避免常规压力恢复或压力降落试井造成低产井降产甚至停产的可能性.计算结果能较好地反映各小层的产液性质. |
| 关 键 词： | 径向流动方程 生产测井 储层动态渗透率 |

| Abstract: | At present, average producing water percentage of the oilfield during mid-later period is more than 80% in our country. Therefore it is very important to estimate production layer and determine planar distributions of reservoir dynamic permeability and press and residual oil. Based on the radial flow equation analyses, the relation between reservoir permeability and produced liquid rate/water absorption, and bottom hole flowing pressure alteration are studied, a method to estimate dynamic permeability of each production layer by production logging data of the oilfield is proposed. This method doesnot need to close wells, and can reduce cost. The result can reflect well the characteristics of produced fluid of each production layer. |
| Keywords: | radial flow equation production logging reservoir dynamics permeability |
