分析了裸眼完成井和射孔完成井的油层出砂机理 ,以线弹性理论为基础 ,同时考虑垂直井眼围岩应力场对射孔孔道稳定性的影响 ,建立了一种新的射孔完井临界出砂模型 ,并编制了出砂预测系统的设计软件。在辽河油田现场应用的实例表明 ,该模型的预测结果与现场工程实践中已有的油井出砂经验预测模型相吻合。 Based on the theory of linear elasticity and considering the influence of surrounding rock stress field of vertical borehole on the stability of perforation tunnel, a new perforation completion is established Well-critical sand production model, and the preparation of sand forecasting system design software. The application in the field of Liaohe Oilfield shows that the prediction results of this model are in good agreement with the prediction model of oil well sand production in field engineering practice.
