Matters need attention for use of the tricone bit

1. Before the bit goes down the well, it is necessary to confirm that the bottom hole is clean.

2. Check whether the thread connection and the nozzle installation are intact.

3.Drilling should be smooth and avoid excessive pressure and rough drilling.

4. The last single root shall start the rotary table with large displacement, and drill the hole to the bottom of the well to fully wash the well and prevent cuttings from blocking the nozzle.

5. When creating the shape of the bottom hole, the bottom hole should be touched steadily with low bit pressure, low rotation speed, large displacement, and low torque. The rotation speed should be 40-60r/min for at least 30 minutes.

6. The reasonable determination of bit weight and rotation speed should refer to the parameters recommended in the bit operating instructions and combine with the actual situation of the formation.

7. During drilling, the operation should be smooth and the drilling delivery should be even. It is strictly prohibited to lift and release sharply, slide and stop drilling.

8. If the drill bit has no footage, the pump pressure increases or decreases obviously, the mechanical drilling speed suddenly decreases, the torque increases and other phenomena, the drilling shall be pooh and checked.

Da Vinci knows half of the things in the sky

In 2020, there will be an explosion in online education, and it is difficult to make no money. Online education will grow slowly in the future. Parents are investing more and more in education.

Hejian Superior Education, Hejian New Oriental, the brands you can think of basically have franchise stores in Hejian.
Now that the competition has intensified, the pressure on primary school students is very high. Going to school is not easier than going to work.
Whether it’s a working adult or a student studying. It will be an age of lifelong learning. No study, no work.
From the future Da Vinci, half of the things in the sky are known, and everything on the earth is known. Wenwu Quancai, Astronomy and Geography Medicine. Also painted Mona Lisa.
