Seabed exploration is very troublesome and very expensive.
The general seabed exploration method is to artificially create seismic waves, and then use geophysical exploration technology to analyze the seabed geological structure, and finally establish a three-dimensional model.
Not to mention anything else, the fuel cost of an engineering exploration ship alone is hundreds of thousands.
In order to create seismic waves, a compressed air gun is placed in seawater.
In order to detect seismic wave data, piezoelectric geophones need to be placed in seawater.
In the previous method, a long trawl was used to place a collection cable and a waterfowl into the water, and the collection cable was used to receive seismic reflections of different characteristics reflected back from each rock layer.
However, this is limited to shallow seas, which can cause large errors in seismic wave detection.
To explore the deep sea, it is necessary to put the piezoelectric geophone on the seabed as much as possible, and the closer to the seabed, the more accurate the data.
This is where manned submersibles come in.
When Huaguo used to use Jiaolong, the cost of equipment for one dive exceeded 2 million, and each voyage made more than a dozen dives, and then it needed to be maintained and burned, and then five or six million were burned.
When it is found that there may be an oil and gas field on the surface, a drill bit is also lowered for testing.
A set of drill bits is tens of millions, and if the test fails, the drill money is wasted.
In addition, Jiaolong is very small, has a limited load, and has a limited capacity of gravity columns used to collect materials on the seabed.
Therefore, there is Jiaolong No. 2.
For this project, Jiang Yuan was actually not deeply involved, he only did two things.
One is to design a 'deep sea super battery' for Jiaolong 2 with the permission of the upper echelons of the country, which increased Jiaolong's 110 kWh battery to 1.2 million kWh, which simply and rudely solved the energy problem, and it is also very rich.
The other is to use scientific and technological directional evolution to enhance the seismic wave analysis technology, which has greatly improved the accuracy and speed of seabed geological imaging.
So, the Jiaolong was reborn!
At that time, when Jiang Yuan took out the super battery--in fact, it was the energy crystallization wrapped in the shell--the Jiaolong project team was simply crazy.
With the same volume, similar weight, and the battery capacity has increased by more than 10,000 times, this is still a battery?!
It's a nuclear bomb, right?
Only then did they understand that it was no wonder that Jiang Yuan wanted to sell the new lithium battery technology, the country had no opinion, it turned out that there was already more advanced technology!
Later, when Jiang Yuan improved the seismic wave analysis technology to an unbelievable level, the engineers of the Jiaolong looked at Jiang Yuan as if they were looking at a god, and worshiped him to the extreme.
Of course, what Jiang Yuan gave them was only a black box for the battery, which was not allowed to be opened no matter what.
With this kind of battery, countless technical difficulties are no longer difficult, and the work efficiency is greatly improved.
Originally, the Jiaolong could work on the bottom of the sea for 10 hours, but now it can definitely increase countless times.
In addition, the lack of battery led to insufficient load, and insufficient load led to a small gravity column, which eventually led to the problem that Jiaolong had to dive and surface frequently, which has now been solved.
Even the cost has been greatly reduced.
Jiaolong actually helps a ton of iron every time it dives, and then loosens it when it floats, which can greatly reduce power consumption, but it is very expensive.
On a voyage, more than a dozen times of floating and diving, more than a dozen tons of iron will be thrown away.
Now there is no need, the electrical energy is absolutely abundant, just use the motor to push up and down, saving a lot of money.
In short, the huge leap in the battery has brought changes to Jiaolong 2 in all aspects.
It's just that at Jiang Yuan's strong request, in order to speed up the research of the Huaguo Deep-Sea Research Institute, most of the Jiaolong No. 2 adopts the same design as the Jiaolong, and the appearance is almost identical.
Because of this, the ultimate diving depth of Jiaolong-2 has not reached the 10,000 meters required by Jiangyuan, only 7,000 meters (this is still the largest diving depth of similar submarines in the world).
Therefore, this Jiaolong No. 2 is actually more appropriate to call Jiaolong Change.
Jiaolong-3, which is being developed by the Huaguo Deep-Sea Research Institute, has completely abandoned the shackles of Jiaolong and made full use of the power of the super battery.
When Jiaolong-3 comes out at the beginning of next year, the purpose of Jiangyuan's 10,000-meter exploration can be fully achieved.
Even so, Jiaolong No. 2 is far from being comparable to Jiaolong.
Alexander had apparently seen the Jiaolong on the news, and he was very greedy for it, and with Jiaolong as a prospecting weapon, his personal wealth could easily be multiplied several times.
It's a pity that with the depraved scientific prowess of the woolly bear, this is destined to be just a fantasy.
In the limelight, the Jiaolong quietly disappeared into the sea.
Thanks to the enhanced motor power, Jiaolong 2 has a diving speed of 50 meters per second, and its moving speed has doubled compared to before, and the one-time continuous working time is more than 200 hours!
Of course, it is absolutely impossible to work 200 hours at a time, there are no problems with the machine, and 3 submariners can't stand it.
Jiang Yuan added Alexander and Maria's to the internal channel, and they could hear the voice report of Jiaolong 2 from DT2.
After three minutes: "Everything is normal, Jiaolong No. 2 has reached the bottom, with a depth of 5813."

Alexander noticed that the engineers around him simply applauded and then dispersed and returned to their workstations, apparently accustomed to this, indicating that the technology of Jiaolong II was very mature.
The chief engineer of the ship began to issue orders: "According to the original plan, the exploration mission will begin, the direction is southeast, and the coordinates are ......"
On land, humans generally use electromagnetic waves to transmit signals remotely, but in the sea electromagnetic waves are severely disturbed.
Jiaolong went thousands of meters to the bottom of the sea, and in order to maintain contact with the mother ship, the method of sound transmission signal was adopted.
The speed of sound waves in the water is only about 1,500 meters, and at a depth of about 5,800 meters, it takes 7 seconds to go back and forth.
So, it took a while to receive a reply from the submariner: "Yes, start the mission."
At this moment, Alexander found himself in front of his eyes a three-dimensional map of the seabed, with a fusiform red icon displayed in the middle, the undulating terrain around it was completely identified, and the distance was blank.
In Alexander's eyes, the red fusiform icon is displayed above the small print, which is also thoughtfully translated into the Mao Xiong language: Jiaolong II, depth 5813, coordinates ......
Soon, Jiaolong 2 began to move, and then a miracle occurred, the three-dimensional map gradually filled, and the underground geology began to be drawn.
Beneath the undulating surface of the seabed, large patches of various colors appear.
"Dark gray is useless rock and earth, black is oil, gray is natural gas, and other colors are various resource minerals."
Jiang Yuan pointed to the virtual image in the air and introduced with a smile.
Alexander was beyond words, he had never thought of such an intuitive and fast way to explore the seabed.
Large patches of dark gray appeared.
Soon, large black and off-white patches began to appear on the northwest edge of the map, spreading all the way northwest and underground, beyond the detection range.
Red iron, blue copper, purple sulfide, yellow manganese, colorful resources and minerals are like stars, distributed in deep and shallow positions on the seabed, waiting for human exploitation.
The riches of the ocean floor have never been so exposed as they have been at this moment.
Jiaolong-2 continued to sail southeast at a speed of 25 knots, and the geological map gradually advanced into the unknown void.
Alexander's breath became short, and his eyes grew greedy to him.
The bottom of the sea is so rich!
The engineering ship on which everyone on the sea followed Jiaolong No. 2 all the way.
At this time, suddenly came the submariner's report: "Discovery of seabed faults, estimated at more than 1,000 meters!"
After a while, a bottomless cliff appeared at the edge of the map.
The second wellhead is coming!
Jiang Yuan's eyes lit up.
