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.

Buy 6 bags of instant noodles and get one free

Instant noodles are really a good food.

When your child goes to school, cook a bag of instant noodles in the morning and add an egg. Can make breakfast quickly.

Before 2020, near the Spring Festival, when he went to the Hejian Credit Building Supermarket, I saw that today Mailang is convenient for promotion, a bag of 2.5 yuan. Buy 6 bags and get a bag of instant noodles. I bought a box directly, and this box of instant noodles really works on top. Really.

The price of instant noodles is getting more and more expensive. Originally it was 1 yuan a bag, now it is 2.5 yuan a bag. It is estimated that it won’t take long for the price to be 3 yuan. Go up. The price of our company’s tricone drills is not going up. Please contact me if necessary, I will do my best to provide you with quality services.

Everyone is arrogant

Now watching TV series, the barrage is more interesting than the TV series.

The plot is good, you can see it by watching the barrage. High-scoring divine dramas are especially 9 or more. Which barrage is the score.

Tencent bought a lot of American TV series are high-scoring TV series.

Later it continued to spread: everyone is VIP, speak to me arrogantly!

Everyone is from Hejian. Give me a bit of arrogance.

Grin is one year old and happy birthday

Grin forks at 542160 today, today is Grin’s birthday. Time passes really fast. At this time last year, Grin announced to fans around the world. A total of 31536000 were thrown to the market in a year.

Grin is also under great pressure of 86,400 coins per day, and consumes 500,000 yuan per day.

As a privacy coin, follow the MW agreement. Created a new era. This new era is successful on the shoulders of BTC. The MW agreement changed the current situation. The MW protocol can be as great in the future as the FTP protocol and the SMTP protocol.

The price of the currency has dropped from dozens of yuan to 7 yuan. Who knows how to go in the future? The mission to change the world makes it unknown from birth to the present.

The success of GRIN is not determined by how much he can sell and how many leeks can take over these production coins.

Locked or not sold is of course accepted by the market, because locked people expect to rise. This is also the consumption.

80,000 yuan a day, valued at 500,000 yuan, the market can certainly be taken on is to consume other things.

The grin token is now a commodity, and miners are involved in producing it. Whether to sell it or not is up to them.

Market acceptance and grin development is faster, I worry that GRIN’s development speed is behind market acceptance

Does the development of GRIN mean that there are leeks receiving 86,400 coins a day?

With the increase of new users and the improvement of infrastructure, the current development of Grin is very optimistic.
