Well completion is tubbiness formula slips for packer

The utility model relates to a well completion is tubbiness formula slips for packer, its characterized in that: the slips body is circular cone barrel, and slips body one end forms annular oblique angle tooth along circular cone bucket circumference, and it has the fracture recess to open to the other end in annular oblique angle tooth one end, solve current well completion packer slip structural design defect effectively, reduced current well completion packer slip and to sheathed tube damage and extrusion deformation, improved current well completion packer setting's reliability and the stability that combination integration completion pipe string was reformed transform in the perforation test, reduced the risk of well completion pit shaft blowby. 本实用新型涉及种完井封隔器用桶状式卡瓦，其特征在于：卡瓦本体为圆锥桶状体，卡瓦本体端沿圆锥桶圆周形成环形斜角牙齿，在环形斜角牙齿端向另端开有断裂凹槽；有效地解决了现有完井封隔器卡瓦结构设计缺陷，减小了现有完井封隔器卡瓦对套管的损伤和挤压变形，提高了现有完井封隔器坐封的可靠性和射孔测试改造联作体化完井管柱的稳定性，降低了完井井筒窜漏的风险。
