气井携砂临界参数与出砂量预测模型应用研究

Study on Critical Parameter and Sand Production Prediction Model and Its Application

为了解决生产中气井产量临界值的相关矛盾,对砂粒直径所需的气体临界流量进行研究。结合气井实际出砂现状及规律,修正已有的携砂临界参数与出砂量模型,探讨出砂气井合理生产制度和冲砂周期的确定方法。

This thesis studies the critical flow rate of gas with a certain diameter of the sand in order to solve the problem about critical production rate in the process of production. Based on the sand rules of wells,this paper modified the model of critical parameter and sand production in the literature. According to the study results,we worked out an approach to calculate rational working system and sand-washing cycle.
