针对水平井和大斜度井修井过程中,遇到的油管打捞困难的问题,研制出了液压拉拔增力工具、可退式液压拉拔锚定器和可退式卡瓦打捞筒,并形成了完整的液压增力打捞工艺,旨在于使用小修作业设备利用3-1/2’’或2-7/8’’的油管在7’’的套管中完成油、气、水井的打捞解卡作业。该工艺可使用小修作业通井机来完成大修作业车载钻机的解卡打捞施工增加通井机的作业能力,同时在打捞解卡遇阻时,通过可退式液压拉拔锚定器和可退式卡瓦打捞筒实现丢开落鱼,安全起出油管柱,减小了施工成本,增加了安全性和科学性。
In view of the difficulties encountered in the recovery of horizontal and high-inclination wells during tubing repairs, a hydraulic drawing and boosting tool, a retractable hydraulic drawing anchor and a retractable slip tube were developed. And form a complete hydraulic booster craft aimed at using 3-1 / 2 “or 2-7 / 8” tubing with minor work equipment to complete the oil, gas and water well in a 7 "casing Salvage card operation. The process can be repaired with a minor repair work through the well machine overhaul operation truck drilling solution to solve the problem of recovery operations to increase the workability of the machine through the well at the same time in the event of a disaster recovery card by retractable hydraulic pull anchors and retreat Slip-on type of slipway to achieve the loss of fish, safe from the string, reducing the cost of construction, an increase of safety and scientific.
