摘要
适度出砂技术逐渐成为油田开发中后期的主要防砂技术。预测砂堵周期对减少作业成本有重要的实际意义。在计算挡砂直径基础上,建立了预测油井冲砂周期的方法,并对现场实例进行了仿真。经油田现场数据验证表明,预测方法简单,计算结果准确,为油田高效生产提供了参考。
Reasonable sanding has been the main technology in the middle-late period of oilfield development.It's very important to predict sand-block cycle and cut down cost of operations.We set up the prediction of sand-washing cycle and simulation of real samples on the basis of calculating diameter of controlled sand.According to real situation,it is validated that the prediction,which has reliable results,is convenient and effective for oilfield development.
