抽油杆卡死井在检泵作业中因人工倒扣安全系数低,作业中往往采取大力硬拔的措施施工,这样抽油杆因受到过大的拉力作用,其性能发生一定的变化,轻者杆体出现塑性变形,性能降低,重者抽油杆严重弯曲直至断裂。抽油杆液压倒扣装置是专门的倒扣工具,与现有的液压钳配合使用,可以安全的倒开被卡死的抽油杆,避免作业中因采取措施不当造成的抽油杆损坏,减少质量隐患,降低油井维护成本。
Sucker rod stuck wells in the pump operation due to manual safety factors with low downtime, operations are often taken to vigorously pull the construction measures, so sucker rod by excessive pulling force, the performance of certain changes, light The plastic deformation of the rod body, performance degradation, severe heavy sucker rod bending until fracture. The sucker rod hydraulic undercutting device is a special undercutting tool. When used in combination with the existing hydraulic pressure clamp, the stuck sucker rod can be safely opened and the sucker rod damaged due to improper measures can be avoided during operation. Reduce quality problems and reduce oil well maintenance costs.
