本文主要研究内容
作者李新妍（2019）在《定向井柱塞气举装置数值模拟及优化设计》一文中研究指出：柱塞气举是排水采气的有效方法,柱塞在井筒中运行可分隔气液防止气体的上窜和液体的回落,充分利用地层自身能量,减少地面设备的举升负担。但在定向井生产过程中,由于定向井井筒中存在造斜段,使柱塞运行过程中气液两相流机理及携液规律更为复杂,常规直井柱塞气举工艺实施效果不佳,制约了定向井开发中后期的平稳生产。为提升柱塞在定向井中的应用效果,本文针对定向井柱塞在实际应用中存在的密封性和偏磨问题,通过数值模拟方法对柱塞结构进行优化设计,并通过实验验证了结构的合理性。针对定向井柱塞的密封性问题,对柱塞外壁的湍流密封槽性能进行研究,对密封槽的槽型、槽深、槽宽以及开槽数量等进行优化。结果表明,柱塞外壁开设凹槽能实现湍流密封效应,明显提高柱塞上下表面压差,增强柱塞密封性,圆弧形凹槽湍流密封效果最好;密封槽深度在接近6mm,槽数为16个时,产生的密封效果最优。针对柱塞在定向井丼斜段不居中和偏磨严重问题,对产生旋转效应的柱塞下部螺旋槽和内部切向孔结构进行优化,对开槽的角度、宽度和深度进行研究,结果表明,螺旋槽和切向孔结构对柱塞产生扭矩,螺旋槽角度对旋转动密封柱塞旋转扭矩影响显著,而宽度和数量对于扭矩影响不大,通过正交实验得到参数最优值为,螺旋升角30度,宽度6mm,螺旋槽数8个;开设切向孔能够产生使柱塞自动居于油管中心的压力,并有效的防止柱塞磨损。在以上优化结果的基础上,通过开展物理模拟实验,得到了对不同气量条件下的柱塞运行规律,计算得到了柱塞的阻力系数,与数值模拟结果吻合较好,证明了模拟结果的可靠性。所优化的设计的旋转动密封柱塞排液性能良好,漏失量小于5%。
