Introduction：

The hydraulic fishing jar features a delay time that remains unaffected by variations in hydraulic fluid properties or downhole temperature, ensuring consistent performance. It delivers powerful impact force to effectively free stuck fish. Equipped with a built-in rapid reset mechanism, the tool enhances operational reliability and significantly improves fishing efficiency. Its large inner diameter allows unrestricted mud circulation and facilitates the passage of auxiliary tools such as testing equipment, providing more options for downhole operations.

Features and Benefits：

★ Stable delay time, unaffected by well temperature.

★ Powerful impact force delivers superior stuck-pipe freeing performance.

★ Large bore design facilitates testing tool deployment.
