摘要
针对江苏油田老式油管捞矛式抽子的胶筒耐磨性能差、密封不可靠、钢丝绳在抽子工作过程中会产生一定的扭矩 ,以及现场更换钢丝绳接头和换取胶筒较困难等问题 ,设计了新型油管捞油抽子。这种捞油抽子采用水力内扩张结构胶筒 ,密封性能更好 ,每抽次的产量将提高15 %,胶筒的寿命是老式胶筒的 2～ 3倍。设计的油管抽子和套管抽子通用的新型钢丝绳快速接头 ,拉力达 116 2 1kN时 ,钢丝绳没有从快速接头中滑出或拧断。设置有钢丝绳破扭装置 ,消除了钢丝绳打扭伤人的隐患 ,并提高了钢丝绳寿命。
The spear-type tubing swab was used in Jiangsu Oilfield, and its rubbers had bad wear resistance and unreliable sealing. Besides, it was very hard to replace the wireline joint and rubbers. Therefore a new tubing swab is designed. The new swab adopts rubbers with inside hydraulic expanding rubbers, which has good sealing behavior. By using the new swab, the oil output in each stroke is increased by 15%, and the service life of the rubbers is 2～3 times of that of the oil swab. The wireline quick coupler and twist-off preventing device are designed, thus the service life of the wireline is also improved.
