Based on the assumptions and scientific research goals previously proposed by relevant experts, the geological survey set a target of “10,000 cubic meters per day, lasting for one week” for this natural gas hydrate trial production project.
Obviously, judging from the current gas production of test production wells, the first goal should be easily achieved.
The only thing to worry about is whether the reserves around the test well are consistent with the original predictions, and whether unexpected situations will occur during the mining process.
As for the second goal, it is also what Lu Jiaxiang is most worried about.
In order for the test production well to operate effectively for a long time, the problem of seabed sediment disposal must be solved. Once there is too much sediment, it will not only affect the efficiency of natural gas extraction, but also cause pipeline blockage. The sand control technology studied by Lu Jiaxiang has surpassed the current level.
The highest standard in the domestic oil and gas development industry. If proven effective this time, this will become one of the necessary technologies for the development of flammable ice in our country.
At ten o'clock in the evening, the lights on the Blue Whale were brightly lit, like a bright pearl in the South China Sea. The flames on the torch arms were still shining into the sky, reflecting everyone's smiling faces.
The workers have already begun to change shifts, taking over from their colleagues during the day, and continue to maintain the operation of the Blue Whale.
The workers who got off work were laughing all the way, especially the workers in the bottom tank, who even went to take photos around the torch arm.
After Feng Chen finished sorting out the day's work log, he planned to patrol the platform for a while and then go back to rest. He happened to see the drilling team leader Lin Jiayou.
"Congratulations!" Feng Chen raised his hand to Lin Jiayou.
"Oh, Feng Gong, we are all happy together!"
The two looked at each other and smiled, then looked at the torch arm together, "Mr. Lu's wish has finally come true. I didn't expect that we really succeeded!"
"Yes, when this incident first started, no one expected that Fuhai Group would be able to create such history!"
While the two were talking, they suddenly saw a technician running over quickly. Feng Chenyi immediately shouted, "Why are you running? Pay attention to safety, you don't risk your life!"
After hearing this, the other party quickly turned around and said, "It's Gong Feng, I have something urgent!"
"No matter what emergency, you must pay attention to safety!" Feng Chenyi said.
"Emergency situation, the sediment in the test well exceeds the standard!"
Feng Chenyi and Lin Jiayou looked at each other and realized that this matter was serious.
"Where's Researcher Lu?" Feng Chenyi asked.
"I don't know. Some people said he was in the restaurant, and others said he was in the dormitory! There was no response on the radio!"
"He must be in the dormitory!" Feng Chenyi said, "I heard that he has insomnia and often sleeps with earplugs!"
"Got it!" The other party hurriedly rushed to the dormitory area.
Feng Chen looked at the other party's leaving figure and said, "It seems that the situation is not good. You go to the drilling team and keep an eye on it. I will go to the consultation room to see the situation!"
"Okay!" Lin Jiayou hurriedly walked towards the drilling platform.
Feng Chenyi also quickly came to the consultation room.
At this time, several people had come to the consultation room, all staff from the Geological Survey. They were nervously recording various data, and they didn't even have time to look up and see who had come in.
Feng Chen raised his head and glanced at the large screen on the wall, which clearly displayed several red-marked items. Among them, sedimentation was already in the alarm position, and the output of natural gas was also slowly declining. This was obviously due to sedimentation.
It is caused by occupying the passage of the test production well.
This situation is very fatal. Once the sediment blocks the test production well, there is almost no room for maneuver. The only choice is to shut down the well and stop mining, which also declares the failure of the test production work.
"Where is the specific data?" Before anyone entered the room, Lu Jiaxiang's voice arrived first.
"Researcher Lu, this is the sediment detection data chart for the last half hour, and this is the pressure change table!"
The few people who were working hard immediately stood up and gave Lu Jiaxiang the form they had just drawn.
Lu Jiaxiang browsed it quickly, then lay down in front of the computer in front of him, carefully searching for various data, and immediately frowned.
"Continue to observe the data and tell me immediately if there are significant changes!" Lu Jiaxiang picked up the walkie-talkie on the table and went straight to the main control room.
In the main control room, Sun Wentong had just been called back urgently from the restaurant. Several experts were also alerted. Everyone was watching the changes in various data and was extremely nervous.
"Commander in Chief!" Lu Jiaxiang greeted Sun Wentong.
"There is a sudden increase in sediment, and the specific situation is unknown!" Sun Wentong did not bother to wipe the sweat on his forehead and pointed at the big screen to preach.
Lu Jiaxiang directly handed over the icons in his hand, "I already understand the situation! The most important thing now is to reduce the influx of sediment!"
"You are an expert in this area, and it is up to you to take command here!" Sun Wentong immediately handed over the command to Lu Jiaxiang.
"good!"
Lu Jiaxiang sat down in Sun Wentong's seat unceremoniously, and he didn't have time to pay too much attention at this time.
"I am the master control room, follow my orders, stop pumping for thirty seconds and increase reservoir pressure!"
After thinking about it, Lu Jiaxiang's first order was immediately issued.
After the test well stopped pumping, the sediment in the pipeline immediately decreased, temporarily eliminating the risk of the test well being blocked.
However, the result is that the output of natural gas also begins to decrease.
"Start the separation and carry out water-soluble circulation sand flushing operation on the sediment in the reservoir!"
Although it is said that water comes from soil to cover it, in Lu Jiaxiang's case, it becomes soil from water. The water generated after the decomposition of flammable ice is used to dissolve the surrounding sediment and wash away the sand.
After a few minutes, the test showed that the amount of sediment was significantly reduced.
"Start the pumping operation and adjust the pressure to one-third!" Lu Jiaxiang looked at the sediment volume data and immediately ordered the pumping operation.
The pressure in the combustible ice reservoir decreases again, the decomposition of combustible ice begins again, and the production of natural gas slowly rebounds.
"What is the current natural gas production?" Lu Jiaxiang asked.
"About 500 cubic meters per hour!" Someone immediately reported the data.
After hearing this number, Sun Wentong raised his head and glanced at Lu Jiaxiang. According to this output, he can also achieve the predetermined goal, which is to produce 10,000 square meters per day.
But obviously this is not Lu Jiaxiang's goal.
"Increase the pump pressure and adjust the pressure to half!" Lu Jiaxiang said.
There was silence in the central control room. Everyone was staring at the various data sent back, for fear of missing that important number, which would bring unpredictable consequences.
"Carry out water-soluble circulating sand washing operation every five minutes!"
As time passed, the number representing natural gas output also slowly climbed, finally reaching the level of 900 cubic meters.
After Lu Jiaxiang saw this value, he immediately went to check the sediment situation. After reading it, his nervous face finally relaxed a little.
"Commander-in-Chief, the hidden danger has been eliminated for the time being!" Lu Jiaxiang breathed a sigh of relief, "If the sediment is still within the changing range after half an hour, we can also slightly increase the pump pressure below to reduce the pressure in the reservoir and increase natural gas production.
!”
"Okay, but you have to remember that this is a trial mining, everything is to verify the technology, don't be too ambitious, everything is about safety!" Sun Wentong was also shocked by what just happened.
Lu Jiaxiang nodded slightly, "I know, I will try my best to maintain a stable output of natural gas while ensuring safety!"
