Fishing Jar Type YSJ
Fishing Jar Type YSJ is designed on the hydraulic principle. It utilizes the drilling string’s elastic potential energy resulting from the elastic deformation. Once the energy is released, a giant upward dynamic load is produced and the stuck accident is released, realizing the goal of fishing and coring operations. When used in combination with the jar intensifier type YJQ, it can generate better jarring effect.
