摘要(Abstract)：

油藏不断注水开发过程中,注入水容易沿着储层中高渗透部位运行,并进一步改变储层的孔渗性质,使其孔喉半径增大,在某一时期注入水会沿着这些高渗透部位突进,形成了不利于油田生产的低效、无效的大孔道。以某一注水井及其连通的油井为单元,利用该单元的动态测试和静态测试资料,研究分析了注水过程中储层的大孔道存在和识别的方法。此研究方法可以在其它注水井单元中推广应用。
In the course of continuous water flooding of an oil reservoir,the injected water is easy to penetrate along high-permeability area of the reservoir and results in further the improvement of porosity and permeability:enlarge the radium of pore and throat.At a certain time,the injected water will break through this area and lead to the formation of low-efficiency and no-effect high-permeability belts that are not desired for oilfield production.Taking one injection well and its connected oil production well as a unit,with the help of the dynamic and static tested data of the unit,the recognizing method to these kinds of belt has been analyzed and studied in the course of water flooding of the above unit' s reservoirs.This study method can be popularized and applied in other water flooded units.
