Chapter 190: Blowout (I)
Hearing the leader's judgment, Tang Feng was also very impressed in his heart, the leader was really a genius in surveying, just relying on some data, he was able to analyze the rock formation and oil layer three thousand meters underground, and the analysis was not bad at all. Tang Feng knew the situation underground very well, and that was because there was a star core, but the leader made his judgment completely based on experience and knowledge.
The leader pointed to the roaring drilling rig and said: "Judging from the data collected a few days ago, the geology here is very good, so the open-hole completion method can ensure the oil yield as much as possible." Although casing completion is also good, it is a pity that according to the geological conditions here, there is no need for this completion method for sand control, because there is very little sediment here. Tang, I have to say, you have found a very good oil field, but it is not clear how large the reserves of the oil reservoir are, but it is safe to say that even if the drilling costs of these two wells are converted, you must have made money from this oil field, and you should have made a lot of money. ”
Tang Feng smiled and said: "Actually, I just feel that there should be an oil reservoir under the deep rock here, after all, there have been multiple layers of oil reservoir near Beaumont, and it just so happens that I bought this land again, so why don't I spend a few million to try it, what if I can make oil?" Looks like I'm really lucky. ”
The head smiled and nodded Tang Feng and said: "You guy has always been lucky, first he escaped the mine accident, and then he dug out those natural silver and natural gold, and what's more, you guy just bought a ranch and actually had a precious metal composite mine" Speaking of this, the head seemed to remember something, and suddenly showed an incredible look on his face, and asked: "I said that you guy didn't know that something was wrong with the precious metal composite mine in Kajabi, right?" How else would you have sold that mine? Now the news from Australia has become a joke in the global mining industry. ”
Tang Feng said with a shocked expression: "Boss, you and I are willing to sell that mine, if we don't fight but Bihe Billiton, why do we want to sell that mine?" Then again, it wasn't me who forced BHP Billiton to buy that mine, it was they who made the first move, okay? If BHP Billiton comes to mine that mine, it will definitely lose money, but if I come to mine it, it will definitely make money! You know, counting that piece of land, my initial investment is only 10 million US dollars, but even if that mine is very special, no matter how you calculate it, it can dig up more than a billion dollars of precious metals, right? They and Billiton have to pay so much money to buy it, it's my business! ”
The leader smiled and pointed at Tang Feng and said, "I'll just say, this is your guy's luck, and this mine, according to the current resistivity change, it is very likely to be another big oil field."
It seems to confirm the leader's words, the leader's words have not been finished, and a "rumbling" sound was heard from the ground, and the drilling rig that was originally rotating at high speed gradually stopped rotating, as if something in the well caught the drill pipe, and at the wellhead position, the gap between the drill pipe and the casing began to erupt a large amount of gas and mud outward
Tou'er and Tang Feng are both experienced people, and when they look at this situation, they don't know that this is a trap rock formation where the drill bit has penetrated the oil layer, and a blowout is about to happen.
"Turn off the wellhead blowout preventer," the head shouted loudly, and ran to the wellhead.
The drilling workers who were working on the well seemed to be very inexperienced, and they had never seen this kind of situation, and the gas and mud spewing out of the wellhead at this time were extremely powerful, so that the workers were scared to run out.
Moreover, the gas ejected from the gap between the drill pipe and the casing became more and more intense, and the sound of "bang" became more and more sharp, and it quickly became a kind of screaming sound similar to that made by a fighter jet when it passed low at high speed.
This kind of sound is extremely scary, not to mention the few scared workers who are scared away and run away at a faster speed, even the head who runs halfway can't help but stop, and after a little hesitation, the head is like a frightened rabbit, turning his head and running back, shouting loudly as he runs: "All personnel evacuate, prepare fire prevention equipment, Clark, notify everyone to come out immediately, prepare the materials and tools for the assault team and the well." All him. Mother. Far away, it's going to blow out."
The so-called blowout refers to a phenomenon in which fluid in a formation is ejected from the ground or flows into other formations in the well, and most of them occur at the site of oil and gas extraction. A blowout is a normal phenomenon, but sometimes it is not a good thing, because when the blowout is often accompanied by flammable and explosive natural gas, or some toxic gases will be spewed out, and if you are not careful, it may cause a natural gas explosion and cause crude oil to ignite, or the workers are fumigated by toxic gases.
There are many reasons for blowouts, but the most important ones are because of a poor grasp of the bottom hole pressure, or the density of the injected mud is not enough, which will lead to the occurrence of blowouts.
The workers who were working were all temporarily summoned from Beaumont, and it was clear that these workers were not very experienced, which led to the blowout.
Of course, this also has a lot to do with Tang Feng. Tang Feng was distracted just now because he was chatting with the leader, and he didn't pay attention to the trap rock formation of the oil reservoir, and when he found it again, it was too late.
You must know that there is a super oil field buried under the pasture at this time, and more than 400 million tons of crude oil are trapped in a big oil bubble by Tang Feng, so you can imagine how big the pressure in that big oil bubble is!
Johnny, who was in the tent in the distance, got out of the tent and shouted to the opponent with an abnormal face: "Boss, the pressure in the well is extremely high, and now it is more than 80 megapascals, let the brothers stay away, this blowout is probably extremely violent"
There are a lot of instruments and equipment in that tent, and all kinds of data in the underground are summarized to those devices through a series of data lines, so all kinds of data in the underground can be clearly observed in that tent. Johnny is on duty today, and he is responsible for observing the downhole data.
Before Johnny finished speaking, the original sharp "Boom" sound suddenly became several times louder, so that others could not hear Johnny's words at all, and everyone's ears were filled with this whistling sound like a volcano erupting.
The next moment, the scene that appeared from the wellhead stunned everyone
