Problems solved by technology
However, the existing jars are relatively complex in structure and contain a large number of wearing parts. With the increase of service time, they are very prone to failure, which brings inconvenience to oil operations; in addition, due to the large drilling depth, how to It is also a difficult problem to drive and monitor the work of the jar in time

The invention relates to the technical field of petroleum operation equipment, in particular to an underground wireless frequency measurement control jet jar, comprising an upper connecting head, a main casing and a lower connecting casing, wherein the bottom of the upper connecting head is inserted into the top of the main casing, And the screw connection between the two is fixed, the lower part of the main casing is sleeved on the outer side of the top of the lower connecting casing, and the two are slidingly matched, the interior of the main casing is sequentially provided with linkage nozzles, jet rings, hydraulic The cylinder body and the flow channel flange, the top end of the linkage nozzle is inserted into the upper connecting head, the bottom end of the linkage nozzle is fixedly connected with the jet ring, the jet ring cavity is opened inside the jet ring, and the jet ring cavity communicates with the interior of the linkage nozzle. The invention is arranged between the drill rod and the drill bit. When the liquid flows through the device from top to bottom, it can drive the piston rod to reciprocate up and down, and then drive the lower connecting shell to reciprocate and hit the main shell to generate vibration, thus helping to enhance the efficiency of the drilling rig , to avoid sticking.
Description
technical field [0001] The invention relates to the technical field of petroleum operation equipment, in particular to an underground wireless frequency measurement control jet jar. Background technique [0002] During drilling operations, due to complex geological structures, improper technical measures, and various reasons such as mud, pipe strings, and wellbore, pipe sticking accidents often occur. The stuck pipe has a great impact on the drilling work, and the harm is also very deep. If it is not handled properly, it will not only consume a long time, lose the drilling footage, but also may worsen the accident and even cause the oil and gas well to be scrapped. The jar while drilling is one of the effective tools to relieve sticking and prevent more accidents. When performing complex well drilling design or predicting that sticking may occur in a certain well section, the best way is to use the jar in the drilling tool assembly in advance. Drill jar. When the drilling ...
