摘　　要：针对受地质资料限制、不能准确描述水体面积和厚度，从而无法利用容积法或者其他方法求取水油体积比大小的储层，从岩石压缩系数的定义出发，衍生推导出利用油藏注入量、采水量、采油量及压力这4项动态参数计算储层水油体积比的公式。该计算公式可应用于水体面积大、地质研究不充分的情况下快速求取水体体积大小。以胜利油田坨28断块东一段为例，用此公式计算水油体积比，与数值模拟方法相比，两者计算结果差别较小．但计算时间明显缩短。Due to the limitation of geologic data, the area and thickness of water body cannot be accurately described. Thereby the volumetric method or other methods cannot be used to calculate the water/oil volume ratio of the reservoir. From the definition of compressibility of rock, the formulas for calculating the water/oil volume ratio of the reservoir are deduced by using the four dynamic parameters of the injection volume, water production, oil production and pressure. The calculation formula can be applied to rapid determination of the volume of the water body with a large area and insufficient geological research. Taking the Dong- 1 Member of the Tuo-28 fault block in Shengli oilfield as an example, the water/oil volume ratio calculated by this formula differs slightly from that by the numerical simulation method. However it consumes a shorter calculation time.
