摘要
通过分析射孔孔道周围的应力分布 ,利用 Drucker- Prager强度准则 ,建立了相应的出砂预测模型 ,分析了射孔方位以及不同的完井方法对油井出砂的影响 ,同时利用有关实验数据对建立的模型进行了验证。
By analyzing the stress distribution around the perforating conduit and using Drucker Prager criteria, the sand prediction model of perforated hole completion is founded. The influence on the orientation of perforation and the different completion methods to sand production is also analyzed. In the meantime, the verification for the prediction model is made by corresponding experimental data.
