After the cementing operation is completed, after careful inspection, it is determined that there are no problems in the entire test production well, and the test production work can be carried out.
The Blue Whale is neither too big nor too small, and any news about it will spread quickly.
Within a few minutes, everyone already knew that the cementing operation was completed and the trial mining work was about to begin. Everyone looked longingly at the ignition tower stretching toward the sea, hoping that they could see the rising flames burning as soon as possible.
.
In the conference room, it was a different scene.
Lu Jiaxiang held a piece of information in his hand and placed some physical objects in front of him, which looked like a pile of mud and sand mixed together.
"This is the specific situation of the flammable ice reservoir in the Shenhu Sea area that we are trying to mine this time!" Lu Jiaxiang pointed at the glass bottle in front of him and said, "This is a muddy silt-type reservoir. This type of flammable ice resource It is not only unique to the Shenhu Sea Area where we are located, but it accounts for more than 90% of the world's discovered combustible ice mineral resources, and it is also the main manifestation of my country's combustible ice reservoirs!"
"So, our Geological Survey has selected this area as the target area for our trial mining of combustible ice, so that we can use this trial mining to provide technical reserves and accumulate valuable experience for the extensive development and utilization of combustible ice.
but......"
I'm scared to speak, especially since the person in front of me is an expert in geology.
There was silence in the consultation room, everyone's eyes fell on Lu Jiaxiang, and Feng Chenyi was no exception.
Lu Jiaxiang continued: “The biggest feature of this muddy silt-type reservoir is that the reservoir not only contains a large amount of combustible ice resources, but also considerable fluid sediment. When combustible ice is mined, these sediments will flow along the combustible ice.
The water and gas decomposed from the ice enter the borehole. Our mining well itself does not have much wellhead and needs to accommodate a large amount of mining equipment. The remaining space is very effective. Once a large amount of sediment appears in the drilling hole in a short period of time
, it will directly block the drilling well and cause the entire wellhead to be scrapped!"
"What researcher Lu said is not alarmist. As early as a few years ago, our neighboring countries had drilled test wells for producing flammable ice earlier than us. As a result, only tens of thousands of cubic meters of natural gas were produced, and the drilling holes were damaged.
The problem of being blocked by sand caused the entire drilling well to be buried by sand, and ultimately the trial mining work had no choice but to be terminated early. Other countries and companies that are researching combustible ice attach great importance to the issue of sand control in combustible ice drilling, but they are unable to completely solve this problem.
!This is also one of the difficulties in mining combustible ice!" Sun Wentong said at the side.
"This time, we have called everyone here. This small meeting is mainly to let everyone understand the difficulties of mining combustible ice. Now Researcher Lu's team has basically solved this problem, but many of the technologies have surpassed ours.
The limit of the oil and gas industry, so the subsequent trial production work must be carried out meticulously according to the established process. No process can be missed, no doubts can be ignored, and no slack can be allowed. We cannot think that everyone is the same.
I have been a veteran for many years, and it is very dangerous to do some things according to my own habits!"
After hearing this, everyone here nodded one after another. Everyone knew that now was the most critical moment, and they could not let go at this critical moment, otherwise the consequences would be disastrous.
Feng Chenyi immediately looked through the information at hand. In order to deal with various situations that may occur during the trial mining process, the Geological Survey Bureau conducted repeated research and comprehensive research on various samples collected from previous drilling.
Finally, a process called the formation fluid extraction trial production method was proposed. Monitoring equipment is used to conduct all-round real-time early warning monitoring of the diameter, concentration and other characteristics of the sediment in the trial production well. Technical means can be used to intervene in the sediment at any time.
Provide effective fluid control for reservoirs containing combustible ice and maintain stable and continuous decomposition of combustible ice.
This method is currently the most advanced in the world, or it is unique and unique.
This time the Blue Whale trial mining is also to verify the effectiveness of this method.
All the methods and processes have not been proven in practice and are just words on paper. Even Lu Jiaxiang, who has done a lot of work on this trial mining method and is very confident, is still a little uneasy.
The main reason is that even if the entire method is very effective in mining combustible ice, it still cannot respond promptly and effectively to the abnormal changes in the seabed. Combustible ice is stored in the seabed in a solid form and cannot be mined.
It needs to be decomposed into water and natural gas as a necessary way to generate flammable ice. Some seafloor formations are relatively soft, such as the Shenhu Sea Area.
Once the decomposition of flammable ice causes insufficient pressure and collapse, this is a situation that must be avoided. In addition to preventing the threat to the production well, the more important thing is to prevent the leakage of a large amount of natural gas.
Therefore, in this test method, Lu Jiaxiang proposed a mining control technology through a large number of simulations and theoretical analysis, which provided strong support for the depressurization test mining of combustible ice.
After Lu Jiaxiang explained in detail the process of trial mining, Sun Wentong stood up.
"Comrades, our combustible ice trial mining work has now reached the most critical moment. We are only a thin line away from combustible ice. As long as everyone follows the procedures scientifically and standardly, I believe that China's combustible ice will definitely be produced in the blue."
The Whale is on fire and will burn brighter and brighter!"
Everyone who had just been worried about the difficulty of mining combustible ice was immediately ignited by Sun Wentong's words.
Yes, now they have the Blue Whale with the most advanced technology in the world, outstanding scientific researchers who have been developing the combustible ice industry for more than ten years, and many ordinary workers who have silently contributed to this trial mining work.
The most important thing is that they are looking for guarantees for the energy security of the motherland. What a glorious and great cause this is.
"Commander-in-Chief, please rest assured that we will make the Blue Whale's torch tower burn brightly day and night without stopping!"
Sun Wentong looked at his watch: "Okay, now let's confirm the time. It is now 8:32 in the morning. Please return to your respective posts immediately and follow the scheduled procedures to prepare to start testing flammable ice at the predetermined points in the Shenhu Sea Area.
The official start time of the mining work is determined to be nine o'clock sharp!"
"Yes!" Everyone present stood up immediately, like soldiers preparing for battle.
"The meeting is dismissed!" Sun Wentong waved his hand, "Everyone is in your place!"
