插管式尾管悬挂器新型丢手技术的开发及应用
Journal of Jianghan Petroleum University of Staff and Workers（2015）
Abstract
在"插管式尾管悬挂器+裸眼封隔器+筛管"分段改造工艺中 ,为使下入的分段改造管柱与送入管柱顺利脱开,研制了专用丢手辅助工具.该辅助工具能够帮助现场操作人员快速、准确判断出管柱"中和点" ,顺利完成丢手操作,降低"中和点"判断不准确造成的反复丢手所导致的复杂井下事故风险.丢手辅助工具主要由上接头、密封筒、滑动芯轴、密封组件、压帽、锁套、O型密封圈和下接头组成.现场应用48口井 ,一次丢手成功率100% .
