摘要
对于边底水能量较为充足的油田,用传统的存水率和水驱指数评价水驱效果其结果不准确。提出了利用物质平衡方法求取各个时期的水侵量,用广义存水率和广义水驱指数评价边底水较为充足油田水驱效果的新方法。应用实例说明,利用该方法可以取得比较客观的评价结果。
For the oilfields with sufficient energy of edge or bottom water, it is not accurate to evaluate water-flooding efficiency by conventional water storage rate and water drive index. Therefore, a new method is developed for these fields, in which the water influx in each periods is calculated with a material balance approach, and generalized water storage rate and generalized water drive index are used to evaluate water-flooding efficiency. Some application examples have indicated that this method can gain more objective results of the evaluation.
