【 摘 要 】

Two important indicators to evaluate the water flooding effect in oilfields are water storage rate and water flooding index. According to the definitions of water storage rate and injection-production ratio and the water flooding characteristic curve, the theoretical relationship between water storage rate and recovery degree was concluded in this paper. In addition, the theoretical relationship between water flooding index and water cut was provided. For Block H, it was demonstrated that the curve of the actual water storage rate vs. water flooding index was above or at the theoretical curve indicated that the actual development index met the oilfield development plan and the water flooding effect was good, and vice versa. Finally, the next improvement measures were given for the problems in development of Block H.
