摘　　要：目的区块具有活跃的边底水,在注蒸汽吞吐长期降压开采过程中,油藏压力下降导致边底水推进,水淹井区含水急剧上升,水侵范围不断扩大.根据区块现有的情况,通过油藏工程的方法,利用Visual Basic 6.0编制程序,计算出目的区块各个小层的水体大小及水侵量,为了提高边底水稠油油藏的最终采收率以及为今后油田进行开发方案的调整提供一定的理论依据.There is active edge and bottom water in the block. Because of the decline of reservoir pressure, the edge and bottom water is advancing, the water cut of the flooding well field is sharply dropping and the water flux area is extending gradually. According to the existing condition of the block, it had calculated the water flux rate and the size of the water body by using of reservoir engineering methods which had been translated into programming language of Visual Basic 6.0. It provided the theoretical foundation for the adjustment of the oil field in the future and for enhancing the final recovery efficiency of the reservoir with edge and bottom water.
