It was very difficult to get a job in a company that had been managing the deepest well on Earth for many years. Hundreds of specialists arrived in the city of Zapolyarny (USSR) in the early eighties of the twentieth century, of which only a few remained, who immediately received apartments in this city for their qualifications, as well as salaries several times higher than Moscow.
Around a kind of telescope into the inner world of our planet (depth 12.262 km) in those years, there were about 16 scientific institutes that studied the extracted rock samples, as well as processes occurring at depth. Currently, it is in Russia, in the Murmansk region (Pecheneg ore district), that the deepest well in the world is located. Its name officially sounds like "Kola superdeep." The record, established once, and even for scientific purposes, has not yet been broken by any other power.
How was the world 's deepest well operated? The name tells us that the work was carried out in the peninsula, which is composed of the oldest rocks on our planet. The equipment used there is not ordinary, since, for example, the drill has a thickness of only 0.2 meters, and at the end of it many devices are fixed. It takes several days to raise and lower the research tool into the well, as the cable can simply break under its own weight at higher speeds.
What did Soviet scientists find out after they had at their disposal the deepest well in the world? The name of many of the phenomena they encountered has not yet been found. For example, once a molten drill was taken out of a mine, the melting temperature of the metal of which is close to the temperatures on the Sun. Another time, something pulled at the bottom of the cable. There are legends that the microphone recorded terrible sounds at a depth similar to the voices from hell, although in fact, geophones that transmit wave patterns of reflection of sound from objects are used at that depth.
In addition to the mystical events, many discoveries were made at the Kola Superdeep, among which there is evidence that our planet has a structure different from that usually indicated in textbooks. Moreover, the lunar soil samples brought by the Soviet lunar rover coincided in their composition with the samples taken from a depth of three kilometers in this mine. This suggests that billions of years ago, the moon broke away from the earth. Unfortunately, since 1995, work at the Kola Superdeep has been stopped. The mine is simply maintained in working condition at the expense of the UN.
The modern deepest well in the world, the name of which is also associated with Russia (the Chayvinskoye field), in fact, is not such, since it is not so much deep as long (12,700 meters, not drilled vertically downward, but at an angle to the surface). The Odoptu-Sea well on Sakhalin, whose length is 12,345 meters, also belongs to the longest objects.
Development at the Chayvinskoye field (Z-42) may today bear the proud title of “the deepest oil well”. The second place is occupied by the Odoptu Sea, respectively, and the third is the facility in Qatar (Al-Shahin oil basin, length 12,289 meters, developer Transushen).
