Maintenance Management and Use of Drill Pipe
1The following provisions shall be observed when transporting drill pipes by heavy-duty vehicles
1. The drill pipe must be placed on the long cushion and tied with a rope.
2. When loading, the male or female joints of the drill pipe should be installed at both ends of the vehicle respectively, and the male and female joints should not be mixed together.
3. In order to prevent friction damage to the shoulder of adjacent joints, isolation measures must be taken to wrap the joints.
4. After a short period of transportation, stop for inspection and re-tie the rope.
2The following provisions shall be observed for the transportation of drill pipes by ship
1. For shipping drill pipes, the male and female joints must wear thread protectors.
2. Put the drill pipe on the sleeper. Sleeper Spacer3About meters, sleepers need to be padded to the same level.
3. Each layer of drill pipe shall be paved with small boards as intervals. The board, deck and sleepers shall be on the same vertical plane.
4. Each layer of drill pipe shall be blocked. All drill pipes shall be bundled with wire ropes with a certain tension.
3When loading and unloading drill pipes, the following items shall be observed.
1. Before unloading the drill pipe, ensure that the thread protector is tightened intact.
2, to avoid rough loading and unloading, because it may drop the drill pipe out of the pit.
3. Don't drop the drill pipe when unloading it, and don't let the end of the drill pipe collide, because even if there is a thread protector, the thread may be damaged.
4. The unloaded drill pipes must be neatly stacked together.
4The following provisions shall be observed for the storage of drill pipes
1. It is not allowed to stack the drill pipe directly on the ground, rail, steel plate or concrete surface. The first layer of drill pipe must be away from the ground.30Centimeters above, to prevent moisture and soil corrosion.
2. The drill pipe should be stored on the pipe rack, and the pipe rack should have enough frame piers to prevent the drill pipe from bending and damaging the thread. The pier should be on the same plane and level, and the pier foot should be solid to prevent sinking.
3, each layer of drill pipe to have isolation shim, do not let the drill pipe joint bear the weight of the drill pipe. Each layer of drill pipe shall have at least three isolation mats.
4. The isolation pad shall be at right angles to the drill pipe and located directly above the lower pad to ensure that the drill pipe does not bend.
5. The length difference of each layer of drill pipe shall not exceed the length of joint or coupling.
6. Both sides of each layer of drill pipe shall be used at both ends of its skid wood.2.5×5.0cm or5.0×5.0The centimeter plug is tightened.
7, drill pipe water eye and male and female screw must be washed with water, and coated with anti-rust oil, wear a good silk protection.
8, during storage to remove the rubber hoop on the drill pipe, otherwise, it will cause annular corrosion groove on the drill pipe body.
9. In order to inhibit the corrosion of the drill pipe, during the storage period, the drill pipe should be inspected by visual inspection regularly, and the surface and inner wall of the drill pipe should be protected from corrosion.
FiveBent drill pipe must be straightened to be used.
After straightening the drill pipe, it is required that the axis of the pipe body coincides with the center line of the joint thread. At present, there are three methods for straightening drill pipes, namely pressure straightening, tension straightening and rotation straightening. All these straightening methods have to produce plastic deformation of the drill pipe. The drill pipe after being straightened is more susceptible to bending at its straightened part than before.
