塔河缝洞型碳酸盐岩油藏单井注水替油技术已成为塔河油田减缓产量递减的最为经济有效的手段。根据原油压缩系数的定义，推导出适用于碳酸盐岩油藏的注水指示曲线（累计注水量—注水期间井口压力），并以曲线分析为突破口，在单井可动用地质储量估算、注水时机确定、合理工作制度确定、油井措施挖潜等方面提出了有益指导，经过近2年的现场实践得到了有效验证，为定量分析改善开发效果提供了有力依据。

The technology of waterflooding to substitute oil in single well is the most economic method to reduce production decline in the exploration of fractured-vuggy carbonate reservoirs in the Tahe Oilfield. We deduce a waterflooding indication curve which is suitable for carbonate reservoir based on the definition of oil compressibility. We analyze the curve, and give some useful suggestions on the estimation of available geological reserves in single well, the time of waterflooding, the suitable work system and the method used to develop well potentiality. Our technology has been used for two years in oilfield, and it provides an effective foundation in the course quantitative analysis which is used to improve oilfield development effect.
