DJ type surface bumper jar is used to produce downward jarring force on drilling platforms only. On the platform, the jarring tonnage can be adjusted in real time, with reliable performance and convenient use. If an accident occurs, the jar can be quickly connected to the drill string to achieve the jarring operation; the effect of dealing with the keyseat sticking, reduced diameter sticking and stuck sticking accidents is particularly significant.
