利用Gompertz模型预测水驱油田合理注水量和注采比

Research on Water Injection Rate and Injection-Production Ratio Prediction with Gompertz Model

基于经济增长和油气资源增长的Gompertz模型,建立了适用于水驱开发油田不同含水时期的合理注水量关系式,绘制了合理注水量图版,并确定了油田的合理注采比。实例分析表明,P油田在目前综合含水率为85%的情况下,合理累计注采比应保持1.44左右。

Based on Gompertz model which is used to predict economic growth and oil ＆ gas resources growth, the relationship of reasonable water injection rate is established to predict water injection rate during different water cut stage. It is also used to draw a reasonable water injection plate and determine a reasonable injection - production ratio. The study shows that the cumulative reasonable injection - production ratio for P oilfield should be 1.44 at the current water cut of 85%.
