摘要:
针对四川盆地威荣页岩气开发过程中出现的套管变形问题,统计分析了套管变形特征,利用有限元分析方法对3种套变形态进行载荷和变形量分析,探讨了威荣页岩气套管变形类型;采用理论分析、有限元模拟、等效试验评价等方法,对钻完井工程涉及的井身全角变化率、固井质量、井筒温压变化、瞬时停泵等工程参数开展了量化分析,得到了不同工程因素对套管强度减弱的影响,表明工程因素不是套管变形的主要因素;通过开展改造过程中地层各向异性、井筒温度压力耦合、储层岩性界面影响等综合因素分析,认为工程条件下套管强度减弱,压裂改造过程中地层薄弱面滑移或储层对套管产生非均布挤压载荷导致套管应力集中而变形,其相关认识为制定威荣页岩气套变防控措施提供了借鉴。
