摘要:
油井出砂是注水开发油田普通存在的问题,有效预测油井出砂规律成为研究重点。运用ABAQUS软件,建立油井出砂预测模型,模拟完成注水条件下地层从原始状态到钻井、充井、射孔、注水开发及油井出砂全过程,分析油井出砂规律。数值模拟结果表明,钻井对井筒周边应力场改变明显;射孔对地层应力状态影响很大,应力集中主要发生在射孔处,在射孔入口处出现塑性应变区,并向四周围岩扩散;注水过程中塑性区扩展不断加大,等效塑性应变区在射孔附近逐渐扩大。
Abstract:
Oil well sand production is a common problem in developing oil fields by water-flooding, hence, production of oil well sand production rules becomes a vital study topic. By adopting ABAQUS software, research has been done to make the prediction model for oil well sand production and imitate its layer. Starting from the layer’s original status, the model displays a complete process of drilling, well filling, perforation, developing in water flooding and sand producing to study the rules of sand production. Numerical imitation reveals that drilling has remarkable influence on the change of stress field around well holes; perforation has striking influence on layer stress status with the stress concentrating in perforating spot. What is more, there appears plastic strain zone in the entrance of perforating spot which radiates to the surrounding well rock. Plastic strain zone expands steadily in the process of water flooding and equivalent plastic strain zone expands gradually near the perforating spot.
