摘要
注水开发的油田中,利用水驱特征曲线进行注水开发效果评价是常用的油藏工程方法,优选符合油田实际情况的水驱特征曲线类型就很有必要。绘制利用甲型、乙型、丙型和丁型水驱特征曲线预测的累计产油量及含水率曲线,并分别与实际累计产油量及含水率曲线进行历史拟合,可以优选出适合的水驱特征曲线类型。通过在A油田的实际应用表明,(1)采用拟合法优选的水驱特征曲线类型符合A油田开发特征;(2)明确了A油田的水驱特征曲线类型为丁型,评估了剩余可采储量,为合理评价油田阶段注水开发效果及编制后期开发调整方案奠定了基础。
It is a common reservoir engineering method to evaluate the effect of water-flooding development by using water-drive characteristic curve in the oilfield,so it is necessary to select the type of water-drive characteristic curve that conforms to the actual situation of oilfield.By drawing the cumulative oil production and water-cut curve predicted by using A,B,C and D type water-drive characteristic curve,and by matching with the actual cumulative oil production and water-cut curve respectively,the suitable type of water-drive characteristic curve can be optimized.Through the practical application in the A oilfield,it shows that,(1)the type of water-drive characteristic curve optimized by fitting method is consistent with the development characteristics of the A oilfield.(2)It is clear that the type of water-drive characteristic curve of the A oilfield is D-type,and the remaining recoverable reserves are evaluated,which lays a foundation for reasonably evaluating the effect of water injection development and compiling the later development adjustment scheme.
