摘　　要：为解决连续油管打捞,钻塞解卡作业过程中常规震击器震击频率低,解卡成功率低,施工周期长的问题,文章研制了一种新型连续油管解卡高频双向震击器,该工具内部无高精度的液压延时机构,以液压为动力源,采用液压力与弹簧力协同作用的方式,达到连续震击的目的,切换工具提拉或下压状态即可快速转换震击模式。文章重点详述了高频双向震击器的主要结构、工作原理、主要技术性能参数和性能特点,对物理样机进行了双向震击模式的性能评价试验,并在大港油田进行了多口井的现场应用。结果表明,研制的高频双向震击器震击频率高,提高了解卡成功率,有效缩短施工周期提高了施工效率,降低了施工成本,具有较广泛的应用前景。In order to solve the problems of low jarring frequency,low success rate and long operation period of conventional jar during the process of drilling plug and freeing pipe operation,a new type of hydraulic high-frequency bi-directional jar for coiled tubing was proposed in this paper.There is no high precision hydraulic delay mechanism inside the tool,and hydraulic pressure is used as the power source,and liquid pressure and spring force are used to achieve the purpose of continuous jarring,and the jarring mode can be quickly changed by changing the state of lifting or pressing the tool.The main structure,working principle,main technical parameters and performance characteristics of the high-frequency bidirectional jar are described in detail.The performance evaluation test of the bidirectional jarring mode is carried out on the physical prototype,and the field application is carried out in several wells in Dagang Oilfield.The results show that the developed bi-directional jar has high harring frequency,improving the success rate of stick-freeing,effectively shortening the operation cycle,improving construction efficiency,and reducing costs.It has a broad application prospect.
