Most narrow channel sand reservoirs are developed by water injection in Bohai area, but there are some differences between the water flooding response degrees. With the use of percolation flow mechanism, the water flooding response time equation of the narrow channel sand reservoir is set up. Through the application of the equation for the field example calculation, the calculation result conforms to the actual result. Based on the different water injection response characteristics, the water flooding response is classified into three types. The result provides an important means for predicting the water flooding response in the narrow channel sand reservoir.%渤海地区窄河道型油田多采用注水方式进行开发,但其注水见效程度存在较大差异.应用渗流力学理论,推导出了窄河道型油田注水见效时间公式,并应用现场实例进行了验证.结果表明与实际情况相符合.同时根据不同的注水见效特征,将窄河道型油田注水见效类型划分为三类.研究为预测窄河道型油田注水见效提供了一种重要手段.
