The utility model relates to a combined type jarring tool, and belongs to the technical field of petroleum and natural gas exploitation drilling tools. The combined type jarring tool is composed of ahydraulic cylinder, a spline outer cylinder, a middle mandrel, an elastic clamping key, an upper connector and an upper mandrel. One end of the upper outer cylinder is in threaded connection with a lower outer cylinder and a lower joint in sequence; the other end of the upper outer cylinder is in threaded connection with a hydraulic cylinder, a spline outer cylinder and an upper joint in sequence;a lower mandrel is arranged in the upper outer cylinder, the hydraulic cylinder and the spline outer cylinder in a sliding manner; one end of the lower mandrel is in threaded connection with a jarring block; the other end of the lower mandrel is in threaded connection with a middle mandrel; the middle mandrel is in threaded connection with an upper mandrel; a locking sleeve is fixedly arranged inthe upper outer cylinder; and two groups of limiting semi-rings are movably mounted on the lower core shaft in the locking sleeve. The combined type jarring tool is ingenious in design and convenientto use, and the problems that an existing jarring tool is single in working mode and poor in risk resistance are solved; and the production and use requirements of enterprises are met.
