Professor Huang's popular science lecture lasted less than two hours. He not only learned about the development history of flammable ice, but also made everyone fully understand the importance of this mission.
The workers have also raised their awareness and have a sense of honor and pride, and they have redoubled their efforts at work. In Professor Huang's words, everything they do now is to add strength to the country's energy security. In the motherland,
In the face of honor, who would relax their strength?
This is more effective than emphasizing in many meetings.
Even Professor Huang himself did not expect that this ordinary science lecture would bring such gratifying results.
The success of the first science popularization lecture surprised the experimental mining team. The Blue Whale Provisional Party Branch immediately decided to fix this kind of science popularization activity and invite experts and scholars from all fields to come and give lectures, even front-line workers.
Come up and tell some anecdotes about your work, so that everyone can learn all kinds of knowledge and safety knowledge in a fun way.
The "Sea Lecture" is in full swing, and in the large conference room of the Blue Whale, a joint meeting on the trial production of natural gas hydrates in the Shenhu Sea Area was also held.
It is important to relieve the boring time during the voyage and ensure the physical and mental health of the workers on the drilling platform, but all of this is to successfully drill a well on the seabed and produce satisfactory flammable ice.
The joint meeting was chaired by Professor Sun Wentong from the Geological Survey and the commander-in-chief of the Joint Trial Mining Headquarters. Researchers and professors from well-known domestic scientific research institutes, as well as the heads of various systems of the Blue Whale attended the meeting.
Feng Chenyi also attended the meeting as a structural system engineer of the Blue Whale and was mainly responsible for providing some key equipment data of the Blue Whale to the meeting.
"Comrades, today's joint meeting is the first plenary meeting of our joint trial mining headquarters. The main topic is to give a detailed explanation of our upcoming trial mining activities, and to deploy future work and clarify all aspects of the trial mining activities.
Now associate researcher Lu Jiaxiang from our Key Laboratory of Natural Gas Hydrates will explain the target area!"
A short young man stood up. He pushed up the glasses on the bridge of his nose habitually, "Dear leaders and colleagues, hello everyone, I am Lu Jiaxiang, from the Key Laboratory of Natural Gas Hydrates. Our laboratory has established
It has an internationally leading combustible ice experimental testing and simulation system, and has obtained a large amount of scientific research data through numerical simulations and experimental simulations. It has conducted in-depth research on the microscopic mechanism of the formation and decomposition of combustible ice, thus demonstrating the feasibility of developing combustible ice!
"
Lu Jiaxiang turned over the speech script in his hand, and then said: "Based on the results of the Geological Survey's previous scientific research surveys in the Shenhu Sea area, combined with a large amount of data, we can basically explain the combustible gases in typical areas such as the continental slopes of the South China Sea and the deep seabed.
Ice storage process, from which we can infer the advantageous storage areas of combustible ice, and use this as a scientific basis to optimize the combustible ice trial mining target!"
"We have currently selected six areas in the Shenhu sea area that are qualified for trial mining. Three of them are key areas and are provided to the trial mining headquarters for selection. The average water depth of these six areas is 1,150 meters below sea level.
The drilling depth is between 190-320 meters, of which the water depth in key areas is 1,200 meters, and the seabed drilling depth is about 230 meters!"
Feng Chenyi quickly recorded some key data in his notebook. Although these will be laid out in the form of a work plan in the future, he still felt that it would be better to record them himself, which would also help his future design work.
"My explanation is over, thank you!" After Lu Jiaxiang finished speaking, he was visibly relieved and sat down.
Professor Sun Wentong immediately said: "Thank you, Associate Researcher Lu, for your explanation! We have currently conducted a detailed study on the geological conditions of three key areas, and the specific trial mining locations need to be determined on-site based on sea area conditions! Now please ask the Geological Survey Bureau
Hydrology expert He Yifang, senior engineer, explained the hydrogeological conditions of the Shenhu Sea Area!"
"Hello colleagues, I am He Yifang from the Geological Survey. Some time ago, through underwater glider navigation observations, we conducted a comprehensive observation of the marine dynamic environment of the Shenhu Sea Area and established the key environment of the hydrate area.
Based on the hydrodynamic change model, through the detection of seabed seismometers, the microvibration frequency pattern related to hydrate activity in the hydrate area was established, and the seafloor microvibration information of the hydrate test production area was established, and the internal waves that may occur in the area were established.
We have made predictions to minimize interference with trial mining activities! In addition, the South China Sea is a typhoon-prone area, and the hydrological changes caused by typhoons are also under our real-time monitoring!"
"What are internal waves?" Many people asked in a low voice. Obviously, for hydrology experts, the impact of internal waves seems to be more important than typhoons.
Professor Sun immediately signaled to He Yifang, "He Gaogong, please spread the knowledge in this area to everyone!"
He Yifang stood up again: "Okay, Commander-in-Chief! Internal waves are a kind of fluctuation inside the ocean. They mainly occur underwater, so they are rarely noticed by people. But for underwater work, internal waves bring
The impact is huge. Internal waves usually occur in stratified media, which are fluctuations between water layers with uneven density in the ocean. As long as the seawater density is stable and stratified, once a disturbance source exists, internal waves will occur. Because
The energy of internal waves is much smaller than that of the corresponding surface waves, and only a small disturbance can cause the formation of internal waves! Therefore, internal waves widely exist in all oceans. Due to the existence of internal waves, the movement of the layered interface
The direction will be opposite, and shearing at the maximum speed will occur at the interface, which can form an internal wave flow of up to 1.5 meters per second, which is extremely destructive!"
"The largest internal wave current in the world once occurred in our South my country Sea, with an amplitude of up to 150 meters and as high as a 50-story building. Such a large internal wave current has caused huge hidden dangers to our deepwater drilling! Although internal waves are not It is as turbulent as the waves on the sea surface, but it is hidden under the water and silent, and is known as the underwater devil. Therefore, after arriving at the operation area, we will strengthen the detection of the internal wave early warning system to ensure the safety of our operations!"
After listening to He Yifang's explanation, everyone immediately had a deeper understanding of the dangers of this internal wave. They did not expect that in addition to the huge waves at sea, there is such a dangerous environment underwater.
Subsequently, the persons in charge from meteorology, scientific research and safety explained their responsibilities in the upcoming trial mining process from their respective professional perspectives, and detailed the countermeasures and solutions in each professional direction.
"Comrades, we will arrive at the Shenhu Sea Area in two days. I hope that all units will remember their respective responsibilities, unite as one, and go all out to welcome the upcoming flammable ice trial mining plan!"
