The scientist Wang Buqiu, who was delayed by the emperor's throne, immediately understood what the so-called black water that can catch fire was after reading this letter.

Although he knew this thing very well, Wang Buxuan was still shocked.

Oil found now?

He focused his attention on the letter again and looked at the location on the letter.

Northwest of Jiuquan County...

Yumen Oilfield...

These four characters instantly appeared in Wang Buxian's mind.

Although what Chen Fengzhi and the others found may not be the main oil well of the Yumen Oilfield, the Yumen Oilfield does not refer to Yumen alone.

Instead, with Yumen as the center, a large circle of oil fields around it are all under the jurisdiction of Yumen Oilfield.

According to Chen Fengzhi and others, the oil field discovered now should be a shallow oil field.

There are many such oil fields around the world. Because they are relatively close to the surface, they sometimes emerge from the ground after being squeezed by crustal movement.

Historically, it was during the Eastern Han Dynasty that this oil field was discovered near Jiuquan County.

Of course, there is also a very common phenomenon in this kind of oil fields, that is, the output is not high and the quality is not high.

This phenomenon is difficult to explain. It may be a part that was squeezed up through crustal movement, or it may be drilled through some tiny gaps.

But no matter whether the output is high or not, as Chen Fengzhi found this oil field in Jiuquan County, Wang Buxu was reminded again.

There is a huge treasure here.

And this is the first oil field in New China, and its output is huge.

Is it difficult to exploit oil fields?

It's really difficult in today's world.

But it’s not difficult at all for Wang Buxing.

As a descendant, even if I am not a professional, I still have some knowledge in this area.

For example, a kowtow machine is used to pump out oil from the ground.

This type is mainly suitable for deep well oil fields.

For those that are shallower than the surface, another method can be used, but it was later replaced with technological updates, but it is still used in some places.

That is water injection.

The pressure of water is used to continuously inject water into the oil well through a sleeve. The density of water is greater than that of oil, so after the water enters, the oil will naturally have to move out.

There is no extra space in the oil well. With the squeeze, the oil can only find a place to survive.

So we can only enter the trap laid by humans and climb up through the oil pipe until we reach the ground.

This method works well at the beginning, but becomes less useful later on.

Moreover, the water content of the extracted oil is too high.

Daqing encountered this problem back then. The water content of some oil wells even reached 80 or 90%. What is this concept?

Ten tons of crude oil are pumped out, and nine tons of them are the water you injected.

Whether it is preservation, transportation, refining, etc., it has caused great difficulties.

As a result, the cost of refining oil is getting higher and higher, and the output is getting lower and lower, so these oil wells have to be shut down.

It was not until new technology was found that secondary development of these oil wells began.

Therefore, for the current Han Dynasty, as long as oil wells that are not deep can be found, they can be mined by water injection.

As for whether it will reach the point where all water is mined, Wang Buxian thinks there is no need to worry for the time being.

Because this thing doesn't have much use, and I haven't even figured out a steam engine yet. How can I still have the energy to develop an internal combustion engine?

Anyway, Wang Buxu felt that there was a high probability that he would never have the chance to see an internal combustion engine in his life.

But oil still has to be mined, because there are many petroleum products that can be used.

For example, lubricating oil can be obtained after refining, which is good news for steam engines.

There are also gasoline, diesel, asphalt, etc. Even if these things are not used for the time being, they can still be processed...

For example, military use...

Learn about burning petrol bombs?

Incendiary bombs made directly from crude oil are not very effective, and their combustion is unstable. Although there are no weather requirements, if the wind is too strong or the rain is too heavy, it will still be useless.

But gasoline is different. Its combustion performance is better and more stable. Once it is ignited, even if it is a clay pot, as long as it can be broken when thrown out, as long as there is a little flame, it can instantly ignite a large area.

If it's not satisfying enough, you can add some asphalt to increase the viscosity.

If it feels unstable, you can also get some white phosphorus and throw it in.

When the time comes, a hot air balloon will come out and white phosphorus petrol bombs will fall from the sky. Do you dare to imagine that scene?

Wang Buxu thought for a while and then said: "The reason why it is difficult to ignite should be that there are too many impurities in it? Can't we find a way to refine it?"

"Uh..." Wang Li looked confused.

The emperor has been thinking about this issue for so long?

Aren't you shocked at all?

Not curious at all?

This seems a bit unreasonable.

"Your Majesty, this thing will catch fire, how can you refine it?" Wang Li spread his hands and said with a speechless expression.

In Wang Li's mind, refining these days seems to be just throwing the raw materials into a furnace and burning them all.

But that corresponds to ore, not this flammable substance.

"If you can't burn it, you can steam it. Try any method. If it doesn't work once, steam it twice. If it doesn't work twice, steam it three times. If it doesn't work, steam it at different temperatures. This little experiment doesn't take much time. As long as you have enough

The black water was made in just a few days!" Wang Buxu waved his hand and cleverly told them the real refining method.

I recommend an app, which is comparable to the old version of the book chasing tool, and can replace all the source books!

Yes, the smelting of oil is that simple. Gasoline can be obtained simply through distillation, because gasoline is the lightest thing in petroleum.

At the same time, different things require different amounts of heat for distillation. Only when this temperature is reached can the corresponding things be differentiated.

Wang Buxian's requirements are not very high. Anything about diesel and heavy oil is just a cloud. As long as he can produce gasoline and lubricating oil, he will be fine.

However, in this case, we still have to work hard on sealing.

Although steam engines have solved some of the problems now, the biggest problem is still sealing.

Without a sealing rubber ring, it is difficult to achieve an absolute sealing degree.

If the sealing degree is not achieved, a very direct problem will occur.

For example, if a steam engine leaks air, even if lubricating oil is added, it will soon leak out through the gaps until it is exhausted.

Now go to South America to find rubber trees?

This is obviously unrealistic. According to Dahan's current technology tree, it is far from being able to build ships for long voyages.

Then only one alternative remains.

FIG tree……

Compared with finding rubber trees in South America, it is easier to find fig trees near the Mediterranean.

After all, we are now near Afghanistan. If we are lucky, we can find fig trees a short distance to the west.

Of course, there seems to be no need to search for it deliberately.

Because Wang Buxu had ordered various places to introduce all the plants that the Han Dynasty did not have.
