Wang Defa's family ignored the matter of Anda, the prince of Boni, "studying and studying" to Liuqiu Island, and went with him. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

His oil well was about to come out...... This will be the first oil well for mankind!

The folk of the Great Song Dynasty now have the best well-drilling technology in this time and space, and it is the highest level of technology, and there is no region comparable to them at this time.

As mentioned earlier, they can drill to a depth of 300 meters, easily penetrate rock, and can easily maintain a wellhead no more than 20 centimeters in diameter.

In all kinds of complex terrain, they can drill brine wells and natural gas wells one by one.

Zhang Guoan, the owner of the island, hired nearly 100 master craftsmen from Sichuan through the Lu family, and in fact, the various sea salt products produced on Liuqiu Island were a devastating blow to other industries and craftsmen in the Great Song Dynasty who made a living from salt production because of their high quality and low price!

Just like the impact on the salt farmers on the seaside of the Great Song Dynasty, the employees of the well salt industry are not having a good time, unless the salt wells that have been drilled earlier can still produce salt, and those that are ready to be dug and even the salt wells that are being dug have been dismounted and can no longer be done, what is the price of sea salt now......

Zhang Guoan's recruitment came at the right time, he not only gave them jobs, but also had a high salary, attracting many original craftsmen to apply, and he had to choose them carefully.

Wang Defa's family also equipped them with better equipment...... At least hardwood is no longer used as a float, bamboo tubes are used as tube sleeves, and there is not even a wire rope in this time and space.

As mentioned above, after the turmoil of the Five Dynasties period, and in the early years of the Great Song Dynasty, the society stabilized again, the economy slowly returned to prosperity, the population of Bashu began to increase sharply, and the supply of salt began to be tight.

At this time, the Great Song government relaxed its control over the salt industry in Sichuan, opened up the private market in Sichuan, and allowed the people there to dig salt wells freely.

In fact, only when there is room for free development, the people's ability to innovate can really come out, which is a basic common sense.

The craftsmen who dug salt wells in Sichuan made bold innovations, adopted small-diameter sinking technology, and invented the "Zhuo Tube Well", which can be regarded as the ancestor of the world's percussion drilling.

Since then, the technology of digging salt in the Great Song Dynasty has reached a new level.

This one is not even included in the technology of any of the major inventions, and it probably appeared in the Qingli period of the Great Song Dynasty, that is, between 1041 and 1048.

Zhuo Tube Well is a small-diameter salt well, and its excavation technology and brine mining technology are generally speaking, including three aspects:

The first is to invent the percussion type of drilling and sinking method, with the drill bit is the so-called "round knife" to dig the well, its driving force is to use the lever principle to lift the head equipped with the "round knife" and heavy objects, and then use gravity to put down, "round knife" can be excavated------ with the deepening of the depth of the salt well, you can also add a strut at any time.

The second is to use the giant bamboo to go to the knot, and connect the end to the end into the well into the casing to prevent the sand and gravel of the well wall from falling and the surrounding groundwater from soaking.

The most important thing is to create the soil extraction cylinder and the brine extraction cylinder, that is, the cooked skin is installed at the bottom of a section of bamboo cylinder, forming a one-way valve, whenever the bamboo cylinder is immersed in the mixture of soil and water or underground brine, the solution will rush the leather valve to open, so that the solution enters the cylinder.

Whenever the bamboo tube is lifted, the solution in the cylinder will be pressed by gravity and the valve will close without leaking.

In short, Zhuo Tuojing's invention is a real innovative invention of the people of the Great Song Dynasty, as long as they are given freedom and opportunities, they can indeed create miracles, which does not need to be led by anyone.

In fact, the technology they have mastered is just right in the eyes of Wang Defa's family...... Even judging from the data of the world's oil wells, it is very likely that it is easier than the brine wells they drilled in Sichuan.

It's hard to say that the first oil well drilled was a self-blowing type!

Of course, their vision can be very optimistic, but the preparation needs to be serious and comprehensive.

During this period, the drilling equipment of the drilling craftsmen of the Great Song Dynasty was mainly composed of stepping frames and derricks.

Briefly describe it.

There is a plate on the stepping frame, and one end of the plate is hung with a drill bit "round knife", and the drill bit "round knife" is a tool for directly digging soil and rock, and the other end of the plate is for people to step on or winch, so that the drill bit is repeatedly lifted up and down, and the impact movement is generated.

The derrick is a bracket used to lift, fish, lift and lift, and it has two forms:

One is a four-legged tower type, and the other is very similar to the "A" type.

The top beam of the derrick is equipped with wooden wheels, also known as overhead cranes.

They use irrigation water to remove the crushed soil or cuttings in the well, or the brine pipe to absorb the liquid in the well, which is lifted and lowered by the rope that passes through the wooden wheel of the overhead crane.

Due to the use of machinery, Dun drilling drilling technology has the advantages of labor-saving, fast drilling speed and the ability to drill deeper wells compared with manual direct digging wells, so it was previously called a major innovation in the history of drilling.

Later, they began to use a large vertical shaft winch car, which is a vertical shaft type hardwood roller, in the drilling of brine wells.

The drum on the winch car can be wound with a long rope------ which is used for lifting and fishing the soil or brine cylinder, one end is fixed to the drum, and the other end passes through the wooden wheel of the overhead crane at the top of the derrick and lowers the suspended two bamboo cylinders into the well, so that the depth at which they remove the soil, cuttings and draw brine is greatly increased.

Therefore, it is really nothing to drill a 300-meter deep well in the Great Song Dynasty.

However, it's not that easy------

One is that it has to work for a long time.

It is normal to drill a well that is more than 100 zhang long, and it is normal to use it for three or five years, and it is normal to use it for ten years if it is deeper...... It's a great investment, and it's risky.

The second is that the excavation process is labor-intensive, as well as animal power.

Think about it, the large winch car with a vertical shaft of more than three zhang is driven by manual or animal power------ which is extremely tiring.

The well is deep, and there was no wire rope before, and bamboo rope was used...... Therefore, accidents often occur when the cable breaks, the drill bit is lost, and the drill bit is stuck due to the collapse of the well wall.

The third is the accuracy of the excavation results.

The investment was huge, and after years of wasted manual digging, the result was nothing...... This is a common occurrence.

Therefore, the great craftsmen with a little ability are extremely arrogant and cannot be easily invited.

In view of these difficulties, Wang Defa's family has made corresponding improvements.

He changed the barrel sleeve to a cast iron type, so that the barrel sleeve was standardized, they had the same diameter, and the interface was the same standard, so there was no need to seal it.

The derrick is also made into a seamed steel pipe, which is not only stronger but also convenient and quick to load and unload.

Because of the use of medium carbon steel, their drill bits are far more than this time and space level in weight and hardness, especially because of the shape of the world's ton drill bits, which is more conducive to impact.

The wire rope specially processed by Wang Defa's master made those craftsmen who dug brine wells surprised and delighted, and they both

I have been a craftsman for many years and have had the experience of digging, so I know very well the help of wire rope for drilling wells.

A master craftsman asked curiously: "Lord Wang, how does this wire rope be solid and flexible?!" ”

Wang Defa's family said: "It's okay to quench better......"

At that time, the master craftsman stroked the large vertical shaft winch with a diameter of ten meters that rotated freely and sighed: "If we had such a sharp weapon, it would be a thousand feet deep......

Wang Defa smiled and said, "You can't use it that deep, in your lifetime, a hundred zhang deep is enough......"

Many years later, Wang Defa's family found that they had said too much, and at that time, they had to march towards Qianzhangshen. (To be continued.) )
