This accident made everyone on the Blue Whale nervous. Fortunately, with the quick and effective handling of the team led by Lu Jiaxiang, the danger was finally averted. Although the whole process only took about half an hour, for the entire trial mining headquarters,
, it is simply longer than a year.
After effective pressure control measures, Blue Whale's natural gas production has steadily rebounded again, maintaining a daily production level of about 15,000 cubic meters.
"Commander-in-Chief, according to calculations, our current natural gas production has exceeded the previous world record set by our neighboring countries!"
Three days later, the statistician brought Sun Wentong a statistical table, which recorded the natural gas production per hour since the test well was exploited, which added up to more than 40,000 cubic meters.
Sun Wentong carefully read the statistical table in his hand, and then handed it to Professor Huang beside him.
"Professor Huang, it seems that our trial mining work was very successful!"
"Don't say that yet, let's see if our production can be stabilized. The accident that happened two days ago is still a bit unsettling!" After all, this is the first time of mining, and Professor Huang has no idea.
Sun Wentong nodded slightly in agreement. Now the mining team is constantly adjusting the pressure in the flammable ice reservoir according to Lu Jiaxiang's plan, trying to control the production of natural gas, and has not fully reached the maximum load production.
In Lu Jiaxiang's words, "We are not a one-time deal. If we only focus on increasing production and neglect the control of sediment, the consequences will be very serious. The goal of our trial mining is to thoroughly explore a set of pressures that can stabilize production."
The control system can effectively realize the sand control work on immature ultra-fine reservoirs and control the mining methods of muddy and sandy combustible ice reservoirs!"
Sun Wentong also expressed great appreciation for this statement. Although the Blue Whale's trial mining project also has the idea of seizing the opportunity and breaking the world record, this is not a priority goal.
Through this trial mining, they want to find a feasible combustible ice mining plan and accumulate technology for future industrial mining. This foundation must be solid.
Although he said that, the daily reports submitted to higher-level departments could not be written like this. Sun Wentong immediately called Lu Jiaxiang.
"Xiao Lu, based on your prediction, what is our maximum daily output?" Sun Wentong asked.
Lu Jiaxiang thought for a moment, then slowly stretched out four fingers, "It should be possible to reach this number, but if we do this, the test well will make the same mistake again, and there is a risk of being blocked by sediment, and if the pressure is too large,
If so, the threat to the reservoir is also increasing. We must ensure the geological safety in the mining area and prevent methane leakage from causing environmental pollution to the atmosphere and water ecology!"
"Yes, this is the first thing we must consider. In this way, you can personally supervise on site to see what the maximum output of our test wells can reach. The premise is that it must be carried out in a safe and pollution-free environment!"
Lu Jiaxiang knew that this was to test the maximum endurance capacity of the entire mining plan, which was the same as the maximum limit of an aircraft. Only by understanding this boundary could a more accurate mining plan be formulated for the future.
"Okay, I'm going to formulate an implementation plan for the maximum mining volume!" Lu Jiaxiang turned around and went to work in the office without saying a word.
Since the Blue Whale arrived in the Shenhu waters, Lu Jiaxiang has been almost the busiest person on the entire ship besides Sun Wentong. Not only does he have to provide various technical support for the trial mining plan, but he also has to write various summary reports and formulate plans.
The corresponding mining plan, after all, whether the entire trial mining plan can be completed on schedule is still unknown.
The maximum daily output tests the safety margin of underground sand control technology. If you are not careful, it will cause very serious consequences. All technical teams are walking on thin ice, carefully adjusting the pump pressure and monitoring the conditions of underground sand, water and natural gas.
real time monitoring.
As the underground conditions continue to change, Lu Jiaxiang directs technicians to adjust various indicators at any time to maintain natural gas production and sand control in a high-risk critical state as much as possible. This is also the final safety boundary. Once crossed, it will cause
Comes with great risk.
As the underground pump pressure rapidly decreased, the combustible ice began to decompose at an accelerated pace. A large amount of natural gas immediately arrived on the Blue Whale platform through the channel. The scale showing the production increased rapidly. The production per hour once again exceeded 1,000 cubic meters, and it is still
It seems to be very easy to keep climbing and break through 1500 cubic meters.
As the production scale increased again, even Sun Wentong and Professor Huang who were watching the battle were a little excited or nervous.
The scale successively broke through the limits of 1,500 and 1,800 cubic meters, and finally settled at the highest point of 2,100 cubic meters per hour.
This value has exceeded everyone's imagination. If calculated according to this ratio, the daily output of the test production well can exceed 50,000 cubic meters, which has reached the production level of mature natural gas wells.
This is simply an unimaginable situation.
Sun Wentong stared closely at the numerical table, his eyes twitching constantly, and he exchanged opinions with Professor Huang in a low voice from time to time.
Just when the two of them were on tenterhooks, the peak output began to slowly decrease. Not only did this change in value not worry the two of them, but they breathed a sigh of relief. After all, flying on the tip of the knife could cause a big disaster if not careful.
wrong.
The natural gas production of the final test production well stabilized at 1,500 cubic meters per hour.
After Lu Jiaxiang stared at the stable output for a long time, the seriousness on his face relaxed.
"Commander-in-Chief, it seems that this is the maximum output of our trial production well!"
"1500 cubic meters?" Sun Wentong looked at this value with an obvious smile on his face.
"Yes, although I can make the test production well reach a production of 2,100 cubic meters, the sand control function will be close to collapse at this value and cannot be maintained for a long time. Only at the level of 1,500 cubic meters can the test production well be able to grow
Time runs!”
"Does this mean we can maintain this state forever?" Sun Wentong asked.
Lu Jiaxiang shook his head slightly: "One or two days is okay. If it lasts for a long time, the technicians may get tired. This output is currently a critical state for sustained high production. According to my speculation, if the hourly output can be locked at no more than
If it is 1,000 cubic meters, the long-term operation of the trial production well can still be guaranteed!"
"That's quite a lot! It's enough to exceed the target set by our superiors!" Professor Huang said happily.
"Yes, yes!" Sun Wenting said happily, "Xiao Lu, you produce according to the output of 1,500 cubic meters, try to understand all the data, and then you can switch to the long-term trial mining mode and completely
We perfectly completed the tasks assigned to us by our superiors!”
