API Fishing Tool Internal Hook For Fishing Drilling Wire Line Fishing Ropes

Product Description:      

    Hook salvage tools are mainly used to salvage cables that have fallen off in the well, wire ropes that have fallen into the well, and other rope and cable objects.

Internal Hook Basic Structure:

    The basic structure consists of a joint, a hook body, and a hook tip. Hook salvage tools mainly include internal hooks, external hooks, internal and external combined hooks, single-tooth hooks, multi-tooth hooks, and movable-tooth hooks.

Internal Hook Working Principle:

    The hook body is inserted into the rope and cable to scrape the rope and cable, and the drill string is rotated to form a entanglement to achieve salvage.

Internal Hook Usage:

  1. The hook should be firm, and the movable-tooth hook fixing pin should meet the requirements.
  2. When the tool enters the well and is 1 to 2 meters above the fish, record the hanging weight of the pipe string.
  3. Slowly lower the pipe string to insert the hook body into the fish, and rotate the drill string at the same time. Note that the hanging weight does not drop more than 20kN.
  4. The hanging weight rises, indicating that the fish has been hooked, otherwise repeat the insertion and rotation until it is caught.
  5. Be careful not to pull up too fast or too hard.
  6. A safety joint must be connected above the fishing hook.

Internal Hook Precautions:

  1. In order to prevent the formation of a "wire piston" and cause the drill to get stuck, a larger diameter anti-stuck joint can be connected to the joint or an anti-stuck disc can be added between the joint and the hook body.
  2. Sometimes, in order to complete special fishing, one of the hooks of the inner hook can be cut off or the hook body of the outer hook can be offset to the axis and the angle between the hook tips can be adjusted to use it as an eccentric fishing hook, which can achieve good results.
  3. Before drilling, a short section with holes should be connected between the tool and the drill string as a well washing channel.
  4. During the fishing operation, the location of the fish can be found by measuring the natural potential and resistance. The fishing depth should be gradually increased from 50m from the top of the fish. The fishing depth should be gradually increased by 5-8m after slowing down for many times, and the fishing depth should be gradually deepened by 1-3 circles every time it is lowered by 3-5m, and then lifted by 5-8m. The method of gradual deepening, slight pressure and lifting, and multiple fishing should never be blindly lowered quickly or increased drilling pressure for fishing.
  5. If the rope-like objects have been compacted and cannot be salvaged with hook tools, you can use the milling pipe column to compact part of the objects and then mill the parts, and then use the inner and outer hooks to salvage.
  6. When salvaging in an open hole, start the pump to circulate and flush the fish head before lowering the fish head; it should also be circulated during the open hole drilling process to prevent the entangled cable from scraping the well wall and piling up the rock cuttings and mud cakes to form a piston, causing the drill to get stuck or causing overflow, etc.
  7. During the process of hook salvage and drilling, if the window point or the casing diameter change point is limited, prevent the casing from being damaged or the salvaged cable from being scraped and falling into the well again.
  8. When using the inner rope scooper under the drill pipe for salvage, its outer diameter must be large enough (8-10mm smaller than the inner diameter of the casing), and the cable is not allowed to pass the rope scooper.
  9. Hook salvage tools must be connected to the safety joint on the tool to prevent them from getting stuck and unable to be removed.
