The hydraulic tool catcher is a safety device mounted below the grease ingection seal control head or Stuffing box.
When the tool is lifted to the top of the lubricator and the cable is removed from the cap, the tool catcher grabs the cap of the tool to prevent the string from falling into the well.
The tool catcher is designed to prevent the tool from falling safely.
The tool catcher is always in the upper position and released by the hydraulic control device.
The hydraulic control tool catcher is a safety device, which is mounted on the lower portion of the seal head and on the upper portion of the lubricator string.The hydraulic control tool catcher is mainly used for automatically grasping rope socket when tools are connected underground and are lifted to the top end of the lubricator, thereby effectively preventing cables from falling off the cable head or instruments drop in wells when the cable is broken when the cable head is impacted on the top end of the BOP because of very fast pulling speed or over big pull force. When a cable rope socket is released, the hydraulic control and grease injection pressure control system is used for pressurizing (operation pressure is no larger than 21MPa) to lead hydraulic force to push the piston in the catcher, the piston drives a robotic gripper which is opened, and then, the rope socket can be automatically released. When the cable rope socket is released, the hydraulic control system is used for pressurizing (maximum hydraulic control pressure should be no larger than 21 MPa.) to lead hydraulic force to push the piston in the catcher, the piston drives the robotic gripper to go upwards, the robotic gripper is braced up by the core sleeve, and then the rope socket can be released. The upper portion of the tool catcher is also provided with a ball valve device, which is also served as the blocking ball valve on the lower portion of the seal head.
Ball Check Valve
Function:After the wire be pulled out,prevent wellhead pressure from leaking.
our company can design and manufacture according to the actual requirements of customers.
