Oil mines under the seabed need to be drilled and extracted using oil platforms, which is notoriously difficult to extract oil at sea, several times more difficult than oil extracted on land. First, the first problem to be solved by offshore oil extraction is the problem of transportation, both by pipeline and by ship.

Second, when you exploit oil at sea, you have to face natural disasters, storms, typhoons, etc., you know, although the sea is beautiful, but when it goes berserk, it is a demon that will bury you in the sea!

Thirdly, it takes a long time to build an oil extraction platform at sea, and the investment is large! Some large offshore oil platforms cost billions to build. Generally, only large offshore oil fields will build such large oil extraction platforms, and if small oil fields are built, they will lose money.

Drill strings and bits are hollow in order to transport debris from drill bits, as well as lubrication and coolant, out of the borehole. The drill strings used in drilling are getting longer and longer, and the drill strings can be joined together using spirals. The end of the drill string is the drill bit. Most drill bits used today consist of three toothed drill discs at right angles to each other. When drilling hard rock, the drill bit can also be equipped with diamonds. This is an important technology for a mining platform that determines the progress and quality of this mining.

However, some drill bits are also available in other shapes. Generally, the drill bit and drill string are rotated by the driving mechanism on the ground, and the diameter of the drill bit is larger than that of the drill string, so that a cavity is formed around the drill string, and a steel pipe is used behind the drill bit to prevent the wall of the drill hole from collapsing. The drilling fluid is sent to the drill bit by a high pressure from the hollow drill string. The drilling mud is then sent back to the surface by the borehole at this high pressure. Drilling fluids must have high density and high viscosity.

Such high-tech, high-tech mining platforms have always been the object of human research, and even Huaxia has made leaps and bounds in the past decade, and it can be regarded as a deep-sea development technology with a certain capacity.

"No wonder the brown-skinned monkeys want to cooperate with an oil extraction company of the US imperialists, it seems that they have to rely on other people's extraction technology." Sun Feng lurked in the water, looked at the semi-submersible mining platform more than a thousand meters in front of him, and muttered.

At this time, a group of workers were busy on the oil extraction platform being built in front of them, and several installation giant ships were hanging giant equipment one by one.

They had no idea that not far from them, there was a person who was spying on them, oh no, watching.

"Voice assistant, let me find out the specific situation of this oil extraction platform." Sun Feng really wanted to know how this semi-submersible starting platform was, after all, he didn't know anything about it, and it was good to know about it.

"Conduct a comprehensive scan and compare the review of the Earth Science and Technology Database," the voice assistant reported the progress.

"This oil exploitation platform is called 'micro semi-submersible oil platform', which belongs to the second-rate technology of the earth, but it is also relatively advanced."

"The miniature semi-submersible** is 90 meters long and 70 meters wide, about the same size as a standard football field, and in the middle of the platform is a derrick about 4 stories high."

"The platform weighs 20,251 tons, has a bearing capacity of 90,000 tons, and can take off and land small helicopters. As a small and medium-sized aircraft with the functions of exploration, drilling, completion and workover. ”

"The maximum operating water depth is 1,500 meters, and the maximum drilling depth can reach 4,000 meters. The total cost of the platform is nearly 2 billion RMB. ”

Listening to the voice assistant's reading, Sun Feng frowned deeply, he couldn't imagine that this small oil extraction platform would cost so much! It turned out to be 2 billion RMB!

"Anchoring can be used up to 900 meters of water depth, with a maximum variable load of up to 5,000 tonnes on deck. The platform is designed to have a service life of 20 years. ”

"The design concept of this oil platform is relatively mature, and the technology and equipment are relatively advanced. In addition to shutting down the wellhead through conventional methods such as emergency shut-off valves, remote sonar, and underwater robots, the platform also adds an intelligent shut-off mode, that is, when the sensor senses an emergency such as a total power loss and pressure loss, the wellhead is automatically shut down to prevent a blowout. Designed to withstand a once-in-50-year super typhoon, it is the first to feature a state-of-the-art intrinsically safe underwater blowout preventer system with self-propelled capability and a dynamic positioning system. ”

After the voice assistant reported the specific data of this oil platform in one breath, Sun Feng nodded, it seems that this mining platform is relatively good.

"It seems that the news report that the United States has deep-sea oil development technology is true, and even this micro oil extraction platform looks very powerful." Sun Feng was silent for a moment and muttered to himself.

This is all science and technology, technology is the driving force of all production!

"Hehe, host, as great as my deep-sea development smart factory to blow them up, it is so troublesome to mine a submarine oil, if we let our deep-sea development smart factory go out, we will kill this small oil field in minutes." The voice assistant said in a disdainful tone.

"You're embarrassed to compare yourself with others, don't you blush?" Sun Feng said with disdain, you are really shameless to compare the technology that is hundreds of years ahead of the earth with others.

"Report to the host, I don't have a face, I won't be red." The voice assistant said innocently.

Sun Feng was speechless, Sun Feng once heard the voice assistant mention that in the heyday of their X galaxy, all the resources of a planet, with enough energy, a deep-sea development smart factory can kill all the resources of a planet in a week.

Therefore, thousands of deep-sea smart factories like this in the X galaxy have been developed to develop the entire X galaxy, and countless planets have been excavated and developed. The resources are estimated to be piled up into a mountain, oh no, I don't know how to describe it when it is piled up into Sun Feng.

Of course, Sun Feng can't do it at present, the first one is that he can't give high-level energy to the deep-sea development smart factory, and he can't even give low-level energy. Intelligent use of the most garbage electricity, even voice assistants dislike the power Sun Feng unimaginable, if he can get advanced energy for the deep-sea development of smart factories, will he develop all the earth's energy in a week, this dream is full of excitement!

"Ahem, don't say hello, host, you won't have this opportunity in your life." The voice assistant interrupted Sun Feng's YY.

"By the way, host, whether we can do this vote or not, let's hurry up." The voice assistant prompted Sun Feng.

Sun Feng found that after stealing the mine a few times, the voice assistant's tone became a pirate, what is the meaning of doing a vote, is it okay to steal openly!
