Percussion drill type drilling relies on the free fall of the drill bit to obtain impulse to break the rock, so the ton drill can only drill vertical wells...... If you can't find the location before opening the well, then everything will be wasted and become a waste well, but Wang Defa's main family has accurate coordinates in advance, so don't worry, just start work directly.

It doesn't matter if the environment of this time and space has changed as much as the vicissitudes of life compared to the world on that side, because the coordinates of latitude and longitude will never change.

Because the rock breaking and carrying rock of the dun drilling are interphased, and the impact force of the dun drilling bit is small, so the efficiency of the dun drilling is relatively low, the speed is very slow, and the time spent to drill a well is long, and because there is no drilling fluid to control the pressure in the process of drilling, if the high-temperature oil and gas reservoir or other complex downhole conditions are encountered, it is very easy to have a blowout or other serious accidents, and the ability to deal with sudden situations is very poor.

But don't worry...... The oil here is a shallow resource, all of which are silt sedimentation structures, and there may be some pressure, but high temperature and high pressure are impossible, and it is impossible to have a high-intensity blowout.

In fact, not long after they arrived at the Wenlai estuary, the well drilling team had already started work first.

All the tasks of Wang Defa's family are to designate the exact location, and he doesn't care about how to build the wellhead, how to dig, and how to lay the casing------ he doesn't care about the work process.

In fact, these craftsmen had more experience in drilling wells than he did------ he had never done before.

In their plan, sooner or later, they will set up a number of drilling teams belonging to Liuqiu Island to raise the level of drilling and exploration to a higher level...... Serve to dig deep wells later.

Wang Defa's family was mainly busy taking everyone to build a settlement area at the mouth of the Wenlai River.

Of course, this is not the location of the Brunei River in the world, but a little more northeast.

Wang Defa's family led the people to build living quarters about a kilometer away from the oil extraction area, and of course he brought enough building materials to build a more formal wharf at the mouth of the river.

He also had to take into account the requirements for transporting crude oil from here to Liuqiu Island, as well as the question of further development in the future, and that this place could not become a place with a single industry.

He ignored the craftsmen who drilled the wells, but the craftsmen kept looking for him, often taking him from the construction site to the oil production site to inspect.

In this time and space, the craftsmen in the Sichuan region of the Great Song Dynasty who could decide the location to dig brine wells were all people who could be particularly valued by the owner...... Their expertise is also legendary: there are legends of see-through eyes, smelling noses and so on, so they are very confident in themselves.

But like this time, the owner directly designated the location, and directly asked them to erect a four-legged derrick to dig, or the first time I saw it, they all became ordinary laborers!

However, the more they played, the more magical it felt...... Some craftsmen said that although this place is leaning against the river bank, it feels like the fire in the earth is very heavy!

At this time, the craftsmen in Sichuan called natural gas and used it to boil well salt, and regarded the reserves of natural gas as fire gas.

Of course, they have also drilled gas wells, and they will also use bamboo tubes to connect them in series to transport it, and the longest pipeline can actually transport gas to a hundred miles away!

Therefore, they felt very strange that there were also earth gas wells with the same heavy fire gas in such a heavy place as water vapor, and they naturally had a trace of worry in their hearts, and they had to find Wang Defa's house once a day to ask questions.

Even when he had just rescued two children and five large buffaloes with his people, they came to him to ask questions.

At that time, one of the craftsmen said that now the smell of fire is getting stronger and stronger, and they have never encountered such a scene!

Of course, the lord of Wang Defa knew what they were talking about the smell of fire, so he said indifferently:

"It's getting heavier and heavier, it only means that the oil is buried shallowly, what are you worried about?! It doesn't smell like rotten eggs......"

Not only did the craftsman not relax, but he was a little nervous...... In the long-term experience of drilling wells, they all know that the smell of rotten eggs means that they have encountered the "dead air" that can smoke the dead, and if they smell it in the process of drilling wells, everyone will scold the bad luck and abandon it.

They did have the experience of the dead.

That rotten egg-smelling gas is actually hydrogen sulfide!

In the process of oil and gas generation or migration, hydrogen sulfide will be produced when sulfur-containing substances undergo thermochemical reduction reaction at high temperature, or sulfur-containing organic matter will be pyrolyzed, which will overflow with oil and gas exploitation......

Hydrogen sulfide, with the molecular formula H2S, is a flammable acid gas under standard conditions, colorless, smelling of rotten eggs at low concentrations, and highly toxic.

However, high concentrations of hydrogen sulfide can paralyze the olfactory nerve, but it does not smell any strange smell at all, and can kill people in an hour or two.

So the ancients were afraid of it because they didn't understand it, and called it dead air.

But Wang Defa's family was not too worried, because from the information he got from that world, the oil wells here were very safe.

Not all wells produce hydrogen sulfide gas.

The oil reservoir here does not have gypsum rock formations, and it does not have high temperature conditions, where can such gas be produced?!

This is common chemical common sense...... However, the well drillers have their own common sense, and they know that when they drill a well full of fire, they may encounter dead gas, so they are a little worried when they see that the fire here is so strong...... Do you want to play again in another place?

It's much easier to drill wells here than in Sichuan, and of course they don't understand that it's all sedimentary soil, and it's hard to encounter rocks...... It's just that I feel that the progress is too fast, and when the day is the fastest, I can go into the ground one foot deeper!

But Wang Defa's family thinks they are really slow enough...... The main reason is that there is no high-power pumping equipment for mud and water mixture, so they can only slowly absorb the mud one by one.

In order to appease them, he still had to go once a day for the past few days, stand there and talk a few words, and then leave.

He hasn't counted it in his own heart...... I didn't encounter a self-blowing well, not to mention, this well doesn't seem to be shallow, and it has been more than ten zhang down, and there has been no response.

Therefore, even if he himself doesn't quite understand, even if he has just escorted the savages back, he still has to go to the oil extraction point to have a look and appease them.

As long as the oil is hit, there will be no tension.

Those criminal savages are all arranged to sift sand on the beach of the Wenlai River, anyway, there are as many materials as there are, and the construction will not stop, and the sifting will not stop.

At that time, the chicken and the dog came to the spiritual head, and they did not herd the cattle anymore, because the buffalo was used to turn the big winch.

The two of them, one with a rattan stick, and the one who worked as an overseer and a master to discipline them!

The two of them have been looking for an opportunity to smoke them, but they have not found ------ wild people are very obedient, men, women and children, and the prime of life are working honestly.

The dishonest are recuperating in the same place where they are held.

Gnawing Dog thought a little and said, "Sooner or later, they will be like us------"

Ji Mi sneered and said, "Impossible, they are stupider than us, they are barbarians!" We are civilized people! ”

The gnawing dog was about to say something at this time, only to hear someone shouting in the distance: "Out of oil, out of oil!" ”

The two hurriedly ran towards the oil extraction point------ and when they ran to the place, they saw a scene they had never seen before! (To be continued.) )
