摘要
常规悬挂器由于通径小无法胜任膨胀筛管完井作业,并会给后续作业带来更大的风险。针对此问题,研制出一种径厚比超过8的超大通径悬挂器,将主体坐封、坐挂、下入传扭、丢手等功能结构全部集成到服务工具中。首先介绍了超大通径悬挂器的结构特点和工作原理,并对核心零部件胶筒进行了有限元分析,然后制造了悬挂器样机,开展了悬挂器的多项性能测试。分析和实验结果表明:防液锁球座密封性能良好;悬挂器坐挂、胀封、丢手动作顺畅,与设计预期相符;悬挂器的胶筒承压大于25 MPa;卡瓦以及基管等结构件可承受50 t悬挂力载荷;其性能指标满足膨胀筛管现场施工使用要求。
Conventional hangers are not suitable for completing the expansion of screen pipes due to their small diameter.This can result in greater risks during subsequent operations.To address this issue,a super large diameter hanger with a diameter to thickness ratio of more than 8 was developed by incorporating functional structures such as main body sealing,sitting hanging,lower input transmission torque,and lost hand into the service tool.Firstly,the structural characteristics and working principle of the ultra-large diameter suspension were introduced.Then,finite element analysis of the core component cartridge was carried out,and the prototype of the hanger was manufactured and a number of performance experiments of the hanger were carried out.The analysis and experimental results demonstrated that the anti-liquid lock ball seat had good sealing performance.The suspension was seated,expanded,and discarded smoothly,which aligned with design expectations.Additionally,the pressure of the cartridge of the hanger exceeded 25 MPa.Structural parts such as kava and base pipe were capable of withstanding a 50 t suspension force load.Overall,the performance indicators met the requirements of on-site construction and use of expansion screen pipes.
