Operation of well drilling machine when adding drill pipe
1. When the depth of one drill pipe needs to be connected after drilling, stop the propulsion first, then stop the rotation, and turn off the cooling water;
2. Stop the rotation and operate the fast forward and backward handle to the fast backward position to make the chuck quickly back in place; 3. The gyrator reverses, at the same time, it retreats the feed oil cylinder to rotate the water braid shaft away from the drill pipe;
4. Operate the clamping handle to make the gripper clamp the drill pipe and open the micro regulating flow valve (right rotation)
5. Connect the drill pipe to be added to the previous drill pipe, and the rotator moves forward while rotating. When the trapezoidal conical thread of the water braid shaft is in screw contact with the conical thread of the newly added drill pipe, immediately operate the gripper handle, loosen the gripper and complete the drill pipe addition.
Drilling rig characteristics
1. The drilling rig has advanced structure and reasonable layout, which is easy to maintain, maintain and repair.
2. The drilling rig has many positive speed stages and 14-500r / min speed range, and the output torque is 13428-250n. M.
3. The drilling rig has a reverse speed of 2 gears, which is convenient to deal with accidents.
4. The drilling rig adopts long travel speed doubling mechanism and mechanical power head, with a travel of 3400mm, which is used to improve drilling efficiency and reduce the occurrence of drilling plugging and burning accidents.
5. The drilling rig adopts double oil pump for oil supply, single pump for drilling and double pump for confluence during tripping; Less power loss and short auxiliary time.
6. The drilling rig is mechanically driven and the others are hydraulically driven, making effective use of power. The overall power loss is small and the drilling cost is low.
7. The crawler chassis is adopted, and the leg oil cylinder has a stroke of 1.5m, which can be loaded automatically and is convenient for relocation and transportation.
8. Some functional interfaces are reserved in the mechanical hydraulic system of the drilling rig, which can be expanded according to the process requirements of different users.
