The operation method and matters needing attention of field drilling

1. Select the wellhead location, dig a round well with the same diameter as the drill bit and roughly equal depth as the drill bit according to the requirements, and put the drill bit into it

2. Align the hole center of the rotary table of the drilling machine with the center of the round well dug, and place the drilling machine. A rope is hung from a pulley above the derrick and attached to an object. The legs are aligned to the center of the turntable hole. Large wooden blocks are placed under the legs to make the legs stable and reliable.

3. Dig a mud pool 2 meters wide, 3 meters long, and 1 meter deep 5 meters away from the drilling machine for mixing slurry when the drilling machine drills into the sand layer.

4, the submersible pump is placed in the water well or other water sources near the good machine point, and the submersible pump is connected with the pressure head with the water pipe. For scouring of soil when drilling.

5, butt drill pipe, diesel engine throttle should be small, try to make the drill pipe not swing around, so as to avoid premature damage to the thread of the drill pipe.

6. When the drill bit encounters the hard soil and the drilling speed is slow, the pressure rod can be applied to accelerate the speed. If the drill pipe is skewed, the hook on the pressure rod can be adjusted.

7, drilling according to the geological situation, determine the use of water or mud to play the soil layer with water, sand must be mixed with mud, so as to avoid a stasis rod.

8. After the completion of the drilling machine, the rod should be withdrawn. When the rod is withdrawn, the lifting wrench should be pulled to rotate the drum and drive the drill pipe to rise through the friction force. Close the valve under the turntable, put it in reverse, and you can retreat the lever.

9. Pay attention to avoid the swinging of the female rod when pulling back, so as not to damage the thread, and the staff should tighten the wire rope. As soon as the thread comes off, it separates immediately. Avoid the relative movement between the external thread and the internal thread, and wear out the thread.
