摘要
尽管国内已经研发出针对于连续油管落鱼的打捞工具,但是在井深较深时或者是在水平井中,由于入井管柱的屈曲,导致管柱上部地压力难以传递到底部,从而使得落鱼抓卡失败。为了应对水平井和深井连续油管落鱼打捞的问题,研制出一套利用液压来更好的抓卡的液压式落鱼打捞矛和打捞筒,该套工具结构简单合理,稳定可靠。通过流动分析,计算了合适的排量。经过实验测试取得了良好的效果,能够有效提升打捞作业效率。
Domestic salvage tools have developed for lost fish of coiled tubing, but it is hardly to transmit the pressure on the top of the string to the bottom because of the buckling in horizontal well or deep well, this may cause the failure. To solve the problem, this paper develops a hydraumatic salvage tool, which is simple and reasonable, stable and reliable.Suitable displacement is calculated using flow analysis. Through the experiment, we obtain the expected effect which can promote efficiency of salvage operations.
