Abstract: In 1993, a formula for critical production rate of oil well in bottom water reservoir with partition board was proposed by Dr. Li Chuan-liang, but this formula did not contain any parameter of well penetration, i.e. did not take the perforated thickness into account. it is hard to just perforate the partition board of well in fact, so a modification for it should be made on Li's formula by adding a critical production rate contributed from the bottom of performed interval to the partition board. Case study indicates that the improved formula is more suitable for the real reservoirs than before.

Key words: bottom-water reservoir, partition board, critical production rate
