Lin Yuan thought to himself: "How mysterious can the source of this technique be, how can I not know the Dao?" So Lin Yuan asked, "Where did it come from?" ”

Li Kai said with a smile: "You should know the original purpose of the appearance of the ground penetrating radar: one is to detect military facilities such as underground tunnels; The other is interstellar sounding, which uses radar to detect the surface of unknown planets. ”

Lin Yuan smiled: "How does it sound like science fiction?" ”

Li Kai said with a smile: "The real technology is often more exciting than science fiction, and the technology of the ground penetrating radar we use comes from the Mars project." ”

Lin Yuan thought to himself: "Mars Project? I haven't heard of it, Li Kai is just a captain company commander, how did he hear about it. So Lin Yuan asked, "How did you hear about this?" ”

Li Kai looked ashamed and said: "Last time, the General Armament Department sent a group of experts to guide us in the use of this type of radar, and there was a young engineer in the group who also liked to play games. ”

"Because there is also an atmosphere outside Mars, and there are often sandstorms on Mars, the optical detection means are greatly limited, and radar detection must be used to find a landing site for the Mars landing rover, and the poles are also probed to determine whether there is an ice sheet on Mars."

"You think, Mars is 200 million kilometers away from the earth, and if you want to fly so far, the weight of the radar system on it will be very low, so the transmitter of this type of radar adopts the most advanced technology, although the volume is very small, but the transmission power is very large, which is the source of our radar technology."

Li Kai was still unsatisfied, and said: "Our country's long-term goal is to establish a Mars base, and even use more advanced technology to change the nature of the Martian atmosphere and turn it into a second Earth." ”

Lin Yuan nodded and said, "Very good, listen to what you mean, this type of radar of ours is enough to discover the oil resources underground?" ”

Li Kai said: "Of course, due to the different dielectric constants of different substances, the reflection and refraction effect of electromagnetic waves is not the same, according to which we can know where there is oil, but the oil is hidden in the ground about a thousand meters underground, so the detection accuracy may not be too high." ”

Lin Yuan said: "How much accuracy can it be? ”

Li Kai replied: "It is impossible to know the situation in the area of 30 meters by 30 meters underground in the road. ”

Lin Yuan said: "Enough, you first probe the oil reserves in the lower reaches of the Liaohe River, and leave the rest to me to solve." ”

In the following days, Beijing dispatched planes to use ground-penetrating radar to map the lower reaches of the Liaohe River, an oil field, not just anywhere drilled will produce oil, oil is fluid, it will flow underground, so it will accumulate in some special terrain conditions, ground-penetrating radar is to locate these places.

Lin Yuan then returned to the industrial zone, planning to organize personnel and equipment for oil exploitation, ancient Chinese drilling technology is still relatively advanced, around 1820, the drilling depth can reach a thousand meters, but these techniques use animal power as energy, so the drilling speed is very slow, it takes half a year to drill a deep well of one thousand meters, which is obviously unacceptable to Lin Yuan.

Lin Yuan then thought that through his existing strength to design drilling technology, but there is no expert in the field of oil exploitation, although there are some technical materials on the Beijing ship, but there are no drawings and process descriptions, even if there are these things are not enough, for the mechanical field, if you have no relevant experience, even if you are given a full set of drawings and processes, the things you produce still cannot reach the original level.

Lin Yuan looked at the information in his hand and drew up a list of experts.

When the experts were invited to the industrial zone by Lin Yuan, they were still confused, thinking: "My major is far from oil exploitation, why should I invite myself?" ”

The first question to be asked was missile expert Gao Ninghai, who asked: "Does the missile have anything to do with oil extraction?" ”

Materials expert Su Zhengming also asked: "My professional direction focuses on non-metallic materials, and isn't it all metallic materials that are needed in oil extraction?" ”

Zhou Huaxin, an expert in gas dynamics, said to Su Zhengming: "The dialectical perspective tells us that everything in the world is interconnected, and perhaps your discipline does have some connection with oil exploitation. ”

Su Zhengming smiled and said: "Lao Zhou, don't just talk about these big truths, then let me ask you, what is the connection between your profession and oil exploitation?" ”

Lin Yuan interrupted everyone's discussion and said with a smile: "Please don't worry, I will answer these questions for you slowly." ”

Lin Yuan turned on the projector, a huge stratigraphic profile map was displayed on the wall, Lin Yuan pointed to the bottom black area and said: "These blacks represent the location of the oil, and above it, there are all kinds of rocks, what we need to do is to break through these rocks from the ground and let the oil come out of the ground." ”

Su Zhengming asked: "When we drill into the oil layer, is the pressure of the oil layer here enough to press the oil out of the ground?" ”

Lin Yuan said: "This needs to be analyzed after we drill wells, but according to historical data, the pressure of the stratum where these oils are located is enough to press the oil from about a thousand meters underground to the surface, that is to say, the wells we drill will be self-blowing wells, and these wells do not require complex pressurized oil extraction techniques." ”

Everyone was happy, if it was a self-blowing well, the difficulty of the technique would be much smaller, Lin Yuan first looked at the missile expert Gao Ninghai, and said: "Elder Gao, if I remember correctly, you once presided over the research of the J-25 ground-penetrating missile, right?" ”

Gao Ninghai said: "Yes, that is, a year ago, when we equipped the aircraft carrier, we had the ability to strike at the mainland of the United States and Japan, in order to attack the opponent's underground hangars, underground command posts and other institutions, the Air Force Equipment Research Institute organized us to carry out research on ground-penetrating missiles, and achieved good results, and now this type of missile has been equipped on the Beijing ship." ”

When Gao Ninghai said this, his face changed, and he said, "You don't want to use a ground-penetrating missile to blow up the formation, right?" ”

Lin Yuan was noncommittal and said, "You can introduce us to this type of ground-penetrating missile." ”

Gao Ninghai said: "Although the name of the ground-penetrating missile sounds novel, it can be classified into the existing missile category, it is a missile that uses a tandem warhead, and everyone is familiar with the tandem warhead, for example, the Red Arrow 10K that we used to hit Japanese warships a while ago, and the tandem warhead was used. ”

"Other missiles deal with targets, many have armor, such as tanks, warships, etc., so the primary warhead generally uses a metal jet to break armor, while the ground-penetrating missile is used to deal with concrete fortifications, so the primary warhead uses the way of penetration, therefore, the missile adopts some special designs, for example, the warhead is made of high-strength materials, so the missile can penetrate into the concrete, in order to prevent the explosive from exploding in advance during the collision, so an inert material is added between the warhead and the explosive."

Lin Yuan asked, "Then can this missile blow up the formation?" ”

Gao Ninghai thought for a while and said, "I also need to think about this, after all, it is a depth of one thousand meters, and the enemy's underground tunnel is not so deep." ”

Lin Yuan said: "Actually, what I need you to do is much simpler than this. ”
