Abstract
A jarring device for a coiled tubing of an oil well-bore is disclosed. A sliding assembly of the jarring device which is slideable within a barrel assembly includes a mandrel and a knocker. The barrel assembly comprises a fluid chamber. The fluid chamber includes an upper chamber, a restricted segment and a lower chamber. Further, a braking assembly is attached to the sliding assembly. The braking assembly includes a ring valve made of an alloy belonging to Aluminum-Bronze family of copper alloys, and which is capable of expanding when exposed to pressure. When the braking assembly is moved into restricted segment, and the fluid within the fluid chamber is compressed, flow of fluid through the restricted segment gets blocked due to expansion of the ring. When the braking assembly exits the restricted chamber, a sudden drop in pressure causes the knocker and/or the mandrel to strike the barrel assembly and generate a powerful jarring impact and shock wave.
