After all, 20 barrels of oil is too little, but there is no way, and it is very difficult to produce more oil without drilling machinery at the moment.

For now, the only place where you can get a lot of oil is probably Baku in Azerbaijan. There are several *** capable of producing hundreds of ships of oil per year. Counted, the annual output is more than 1,000 tons.

But Baku is located in Central Asia, too far from the North Sea State. Moreover, land transportation is extremely inconvenient. Because, this needs to pass through many countries, and it is easy to be intercepted and plundered by robbers. If you take the sea route, it is safe. Because, it only needs to pass through the country of Persia. Azerbaijan has belonged to Persia since the establishment of the Safavid Empire. It was snatched by Turkey for a while, and then, in the 19th century, it was snatched away by the powerful Russia.

That is, if you want to import Baku oil, now you just need to look to the Persian Safavid Empire.

But the problem is that to get to Persia by sea, you need to make a detour throughout Africa, and the journey is extremely long. Even if it is shipped back thousands of miles away, it will be hundreds or thousands of tons at most. If it is refined into gasoline or diesel, it is estimated that it is even less.

Although the multi-stage fractionation column could not be built, Marin also thought of a method of local method of fractionating gasoline and diesel - the multi-step refining method......

That is, it is distilled and collected in a step-by-step process at multiple temperatures. In this way, gasoline and diesel, as well as kerosene, are also available. Lubricating oil can also be refined......

However, in this way, the energy consumption is very large, and it is far less fuel-saving than the one-step method of multistage fractionation columns. But Marin owns the Ruhr coalfields and will own England coal in the future, so he is not worried about energy.

And the big problem is that Marin can't make gasoline engines......

Seeing that a barrel of gasoline has been made, if Marin can build a car or a motorcycle, he will probably be able to get started immediately. However, Marin doesn't know how to build a gasoline engine......

In his middle school physics textbook, Marin learned the principle of piston motion in an internal combustion engine. However, understanding this principle and building a gasoline engine are completely different concepts.

Not to mention, the spark plug on the gasoline engine alone is not a technical problem that Marin can solve. And the principle of multi-cylinder gasoline engine, Marin does not understand.

Therefore, even if the gasoline and kerosene gasoline engine are distilled, they are in vain, and they can only be used as "fire oil" for fire attack.

However, for diesel engines, Marlin has some experience. Why? Because Marin had a second-hand walk-behind tractor at home in his previous life......

Second-hand walk-behind tractors, how broken do you say? Repairs or something are common. In the previous life, the second-hand tractor of the Marin family was used for more than ten years, and it had to be overhauled almost every year. Later, Daddy Marlin became an expert at repairing hand-held tractors. And Marlin, who often plays a role, has also basically figured out the structural principle of the single-cylinder diesel engine of the walk-behind tractor.

Of course, it's not so easy to build it right away. Because, the fuel supply system in the single-cylinder diesel engine, as well as the transmission belt and other inconspicuous things in later generations, are relatively advanced technology in this era.

In addition, even if the single-cylinder diesel engine is out, there is no diesel burning, which is the biggest problem. That's why Marin now let Leonardo da Vinci exclusively supply the steam engine. Because, coal is easy to mine and easy to obtain.

In addition, the single-cylinder diesel engine, even if it is imitated, not to mention that there is no diesel burning, its horsepower is not enough, and it can drive a boat at most. As for the sea ships of several hundred tons or thousands of tons, they cannot be moved. And now that oil is so scarce, even if a horizontal bar diesel engine is made, the use value is not great. As for the more advanced multi-cylinder diesel engine, Marin doesn't understand the structural principle and can't figure it out......

……

However, diesel engines are to be engaged in after all. However, Marin plans to wait for the first batch of middle school students to graduate and enter the university, and then teach them mechanical manufacturing by himself and Ada.

By the time these junior high school students go to college, Ada will almost become a master of steam engine manufacturing. When the time comes, Ada will be in charge of teaching them how to make a steam engine. And he is responsible for teaching them the structure of single-cylinder diesel engines. Then, let these young college students go and copy the single-cylinder diesel engine. Even if he can't enjoy the benefits of the era of the internal combustion engine, his son Caesar may be able to enjoy it.

However, there is one problem that must be solved first - and that is the problem of oil supply......

Diesel engines are made to drink oil. When there is no fuel for a day, the diesel engine will become an ornament. Therefore, it is necessary to get a stable supply of oil first.

However, at the level of drilling in the current era......

……

"No, it seems that there is an ancient method of digging a well hundreds of meters deep!" Marin suddenly remembered something.

It seems that in the middle of the Chinese River, there is a technology for digging deep salt wells, what is it called......

Marin fell into deep thought and began to search for the fragments in the depths of his memory. Finally, he found the relevant memory - Zhuo Tsutsui......

Zhuo tube well is a very traditional hand excavation of the deep well to extract salt brine, is the ancient ancestors of Suining Daying County in central Sichuan used a large-caliber Nanzhu tube, first chiseled a big eye, and then used the Nanzhu tube to isolate fresh water infiltration, and then in the Nanzhu tube, the use of the iron cone tied to the top of the drill pipe, deep into the bottom of the Nanzhu tube. People use the principle of levers on it, step on the levers, and let the tied drill pipe with iron cone chisel the bottom soil up and down until the depth of the well reaches more than 100 meters, and a high concentration of salt brine seeps out......

This process is very long, because the method is very primitive, and it takes sixty or seventy days to drill a Zhuo tube well more than 100 meters deep. However, this is already the deepest record of ancient well sinking. Moreover, this technology appeared as early as the Northern Song Dynasty.

That is to say, if Ma Lin sends people to Suining Daying County in the middle of the Daming River now, he will be able to find the craftsman who excavated the Zhuo Tube Well. If you ask those craftsmen to help dig the oil fields......

However, there seems to be no bamboo in Europe, let alone a thick bamboo. Therefore, a complete set of tools had to be introduced from the Ming Dynasty.

However, the Galicia region of Poland is not its own territory, and it is not clear who will be cheaper to dig a Zhuo tube well there. And the Baku oil fields in northern Persia do not have their own share......

"By the way, it seems that there is an oil and gas field called 'out of the sulfur pit' on Taiwan Island. It seems that this oil and gas field has had oil seedlings exposed to the surface very early, and it is said that it is still the first modern oil well in China......"

In his previous life, Ma Lin had read an article written by the Wanwan people on the end of the world, boasting about how old the sulfur pit oil field on Taiwan Island was, and it was the first modern oil well in Asia.

Later, Marin checked the information and found that it was indeed the case. Located on the bank of Houlong Creek, the pit was discovered as early as 1817. Then, in 1861, a man surnamed Qiu dug a shallow well more than 3 meters deep, producing 40 kilograms of crude oil per day......

Moreover, Ma Lin also checked the satellite map and found that this pit is located in the riverside area on the south bank of a bend in Houlong Creek in Miaoli County.

It's just that although this oil field was developed early, the output is really not good. Moreover, this oil well was also cheaper for the devil, and during the Japanese occupation era, it provided the devil with 170,000 tons of crude oil. It's just that these amounts are still too small. That's why the devil went to the United States to import. After being cut off from imports, he took the risk of starting the Pacific War. Of course, it is also due to the small production of sulfur pit oilfields. Otherwise, the devil would not provoke Lao Mei. And provoked Lao Mei, which naturally accelerated the defeat of the devil......

A shallow well more than 3 meters deep produces 40 kilograms of crude oil per day, what if Marin hired a master to dig Zhuo Tube Well to drill a few or even a dozen deep wells 100 meters deep? It is estimated that the production will be very impressive......

Marin also does not want to know how much oil can be produced from the sulfur pit oil field, as long as it is enough to maintain the development and testing of diesel engines. When the diesel engine technology is mature, it is not too late to develop large oil fields. When the time comes, diesel engines can be used to drive high-manganese steel drill bits to drill deeper wells to provide more oil. What's more, Marin still knows in his memory that a self-blowout well with a daily output of 10,000 tons can be drilled on a small plateau called "Spindle Top", 137 kilometers east of Houston, Texas, south of Beaumont City. The high ground at the top of the spindle is said to have a foul smell of sulfur, which is a manifestation of the exposed petroleum oil seedlings, and it is easier to find. Moreover, the place is not far from the sea.

It's just that the Lucas well at the top of the spindle is several hundred meters deep, and there are solid rock formations in the middle, which cannot be drilled through an old-fashioned well like the Zhuo Tube Well. Therefore, this requires the use of a mature diesel engine to drive a strong drill bit to drill through it. And once the rock formation is drilled, the Lucas well will spew out 10,000 tons of oil per day, which will make Marin or Marin's son no longer short of oil......

However, Lucas's well is only a long-term goal, and whether Marin can see it in his life is a question. However, it is still more realistic to use Zhuo Tube Well to dig out the oil and gas field of sulfur pits.

Thinking of this, Marin opened his tightly locked secret diary, and wrote the words "Zhuo Tsutsujing" and "Out of the Sulfur Pit" on a new page of the diary. Then, I locked the laptop again......
