Sioux City is very aware of the gap between Dahua Industrial and Daqing. He not only asked Li Lianxiang and others, but also learned when he was in school.

However, the gap in pure technology does not mean the gap in practical effect, Su Cheng smiled lightly and asked back: "Daqing's technology is really good, so you use ionized carburizing tubing?"

Xue Jie's tone was sluggish, but he did not twist, and said neatly: "Carburizing and quenching! The effect of carburizing without ion carburizing is good, and the wear resistance is about the same as that of your full set of equipment." But there's one thing you're missing. ”

"Oh?"

"You don't do corrosion-resistant treatments. Oil well eccentric grinding is not only a problem of hardness and straightness, but also has a great relationship with oil and gas corrosion. There is only anti-wear, no anti-corrosion, and the effect cannot be improved at all. Xue Jie finally showed a smug look, but she didn't want to make people feel angry when she didn't have to celebrate Daqing in Chapter 70 (rolling horizontally for a monthly ticket). For a beautiful girl, rich expressions will only increase her charm.

But Su Cheng only glanced at it, then withdrew his gaze, and repeated lightly: "The technology of Daqing Machinery Factory is indeed good. ”

"You don't believe it?"

"Believe, and I know, you're lined with resin. Su Cheng's expression was even more relaxed than before.

Xue Jie was very reluctant, but couldn't help but ask curiously, "How do you know?"

There are many ways to resist corrosion of tubing, such as nitriding, chrome plating, blackening, multi-permeability, etc., and the process of lining resin is suitable for tubing, but it is not a common means. Xue Jie didn't want to be curious, but she was really curious.

Su Cheng looked at the progress of the workers behind him, and said lightly: "Because you can produce your own resin." ”

What is the reason for this. Xue Jie was stunned, but after thinking about it, the factory chose to line resin as an anti-corrosion measure, which did not mean to support the resin factory.

Annoyed for a moment, Sioux City had returned to the oil well where he worked. Xue Jie couldn't help but chase after him. "Since you guessed, you should know." The effect of our specialty tubing. More than twice as good as your anti-deflection system, you're doomed. ”

Su Cheng smiled: "You didn't do the corrosion-resistant Chapter 70 Daqing also (rolling sideways to ask for a monthly pass) It's okay, if you do corrosion-resistant, you will lose." ”

……

Xue Jie only felt that Su Cheng's smile was full of hatred.

She has a strong curiosity about everything. This is especially true for petroleum technology. Her curiosity led her to ask Su Cheng several times, which was already at the limit of what she could bear.

However. Sioux City still left her with a puzzle.

Xue Jie returned to the hotel, thinking about Su Cheng's words.

When the director who led the team saw it, he immediately asked with concern: "Xiao Xue." Got into trouble?"

"Director Zhuang. Xue Jie hesitated. talked about the process of encountering Sioux City today, and asked: "I thought about it, but I didn't understand why we didn't do corrosion resistance, but if we did corrosion resistance, we lost." ”

Director Zhuang laughed and said, "He's bluffing you." Students in the Department of Chinese are like that. The thunder is loud and the rain is small. I also graduated from the Department of Chinese. ”

"I don't think so. Xue Jie shook her head.

"I don't understand the technical stuff. I've heard, though. Our high-frequency carburizing tubing is only one generation behind the one imported from the United States, and the lining resin is the most advanced technology......"

Xue Jie pursed her lips and smiled, and said, "Director Zhuang, you are timid, our carburizing and quenching process is better than the high-frequency carburizing process, and the wear resistance is twice as high." ”

"Alas, yesterday's endorsement was poor again, and I always feel that the high-frequency ones are more high-end. Director Zhuang smiled and said, "Since it's so good, will it be a cost problem?"

Xue Jie shook his head lightly and said, "They are 2,000, and we are 4,000, although it is twice as expensive, the effect is more than twice as good." They don't even do corrosion resistance, and when they are used in high-yield oil wells, they will have problems in a year, and the trouble-free time may only be half a year. I think they're probably trying to compete for other wells?"

Director Zhuang immediately cooperated: "That should be." In addition to the high-yield oil wells, there are more than 10,000 other oil wells in the Shengli Oilfield, which is enough for them to eat. ”

"The equipment of high-production oil wells is updated quickly, and for low-grade oil wells, it is good to change the equipment once every 10 years. Xue Jie said, in a good mood, and said: "Our goal is to have high-yield oil wells of more than 100 tons, and there are about two or three thousand wells in Shengli Oilfield, which have always used our tubing." 4,000 yuan a year, more than half cheaper than imported products, and save foreign exchange. Other petroleum machinery factories use either gas nitriding or high-frequency carburizing at a price, which is not as good as ours. ”

Xue Jie was relieved on the surface, but when she returned to the room, she was still puzzled: why did Su Cheng say that he had lost!

By this time, she had tied herself to the machine factory.

After a few days, the Shengli Oilfield Product Department inspected the sucker rod and anti-eccentric wear system installed by both sides, and after giving the appraisal results, the leaders were consulted and everyone was called together for a meeting.

Xue Jie and a group of officials from the Daqing Oilfield entered the conference room, and saw that the conference room had been set up as a four-party meeting. Beijing Petroleum Machinery Factory, Dahua Industrial, and Shengli Oilfield were on one side, and Su Cheng sat at the side of the conference table with his head held high, and he was wearing a suit, nodding to her.

Xue Jie was stunned for a moment, and quickly nodded, and when she paid attention again, Su Cheng was already whispering to the people around her.

Daqing came to a department-level cadre, and Shengli Oilfield sent Lin Yonggui, a department-level officer, to preside over the meeting, which was considered to be of the same level between the two sides.

Beijing Petroleum Machinery Factory is a veteran petroleum machinery factory, perhaps too old, regional pressure is great, the enterprise situation is not as good as a year, all over the world to spread out salesmen, hoping to bring back some business.

Such a meeting will be held almost every year, everyone is familiar with the process, after a brief introduction of the products of all parties, it is the stage of bargaining, as the host of Shengli Oilfield can also compare the price and quality to the greatest extent from this process.

Xue Jie made a five-minute technical explanation clearly and sat down confidently. I saw that Dong Jianjiang, the representative of the Northern Stone Machinery I had seen, had a very ugly face, and I couldn't help but feel proud in my heart. The process of carburizing and quenching was conquered by her people for a year and a half, and the technical content is second only to Changqing Oilfield in the whole country. The difference is that Changqing Oilfield purchases foreign technology, and the quality is better, but the price is about 9,000 yuan, which is only used in high-yield inclined wells that are easy to deflect and grind.

Dong Jianjiang was the second to stand up, and he simply did not introduce his own high-frequency carburizing pumping pipe at the same price, but talked about the conventional quenched nitriding tubing and the conventional quenched blackened tubing. The prices are quite competitive, after all. Processes like nitriding are inventions before World War I. The cost does not increase much compared to ordinary pipes.

In contrast, the leaders of Shengli Oilfield listened very carelessly.

On the contrary, it was Sioux City, who listened extremely seriously.

Another five minutes later. It's Dahua Industrial.

Sioux City stood up, and it took two minutes. After introducing the three departments of the anti-deflection system, and after introducing the patent situation for another minute, he suddenly said: "The anti-deflection system is the same as the traditional anti-deflection method. There is one biggest difference. It's our system stackability. Use our anti-deflection system. Any kind of sucker rod can be used, and we did a comparative experiment......"

This sentence alone made Xue Jie have a bad association.

Several technical officials of the product department of Shengli Oilfield nodded again and again. The anti-wear system is a first-class system, which is its biggest selling point.

As for the price of a few thousand yuan, for resource enterprises that do not worry about sales. Not a problem at all.

Director Yang sent down a stack of printer paper, and Su Cheng continued: "The main enemy of oil well eccentricity is wear. Let's start by talking about wear resistance. For example, in the case of a sucker rod quenched by ordinary quenching, the level of anti-wear force is increased by 3 times with the addition of our anti-eccentric wear system, the level of anti-wear is increased by 6 times with the sucker rod quenched with high frequency, and the level of anti-wear force is increased by 9 times with the sucker rod quenched by carburizing and quenching. Regardless of which scheme is adopted, the level of wear resistance will increase and the price will be reduced by ......"

Su Cheng paused for a moment, and continued: "For the demand for corrosion resistance, we divide it into two types, deep vertical wells with a daily output of less than 100 tons, and ordinary quenched sucker rods with anti-eccentric wear system and blackening treatment, the effect is equivalent to using simple carburizing and quenching chrome sucker rods, but the price is only one-third of it. For high-yield deep inclined wells, anti-eccentric wear system and chrome-plated sucker rod can be used, although the price has increased by 2,000 yuan, the service life has been increased by more than 2 times. ”

He looked at the direction of Daqing Machinery Factory and added: "The anti-eccentric wear system with chrome-plated sucker rod is better than the sucker rod with ionized carburizing resin imported from abroad......"

Xue Jie closed her eyes slightly. She only now understands why Su Cheng said, "If you do corrosion resistance, you will lose." ”

Because the main enemy of anti-eccentric wear is wear after all, although corrosion will cause the anti-wear ability of the sucker rod to decrease, but Dahua Industrial's anti-eccentric wear system does not directly contact the crude oil, they are locked on the sucker rod with clamps.

Therefore, the low corrosion and strong wear conditions faced by the sucker rod in the past have become low corrosion and low wear when combined with the anti-eccentric wear system. If Daqing Machinery Factory does not do corrosion-resistant specialized treatment, but also fight for anti-wear ability, once the corrosion resistance, the other party casually add a nitriding pipe, their lining resin will become a pure cost......

In fact, with a price of more than 4,000, they have no profit.

Daqing Machinery Factory looked at each other stupidly for a while, and they didn't know what to say. The anti-eccentric wear system comprehensively surpasses the lining resin carburizing and quenching sucker rod of Daqing Machinery Factory, which makes them full of confidence a little unacceptable.

In terms of oilfield, after a private discussion, Lin Yonggui announced: the purchase of 5,000 sets of anti-eccentric wear systems.

Daqing's sucker rod only received a symbolic order of 100 pieces, and it is estimated that it is also used with an anti-eccentric wear system.

On the contrary, it was a blessing in disguise for Beishi Machinery, and sold more than 4,000 pipes of various types at once, although the price was very low, Dong Jianjiang, who was also happy, had hazy eyes, took Su Cheng's hand and said: "The wages of thousands of people in our factory are down, and the old men are not afraid of hardships and hardships, and they can't let women and dolls eat chaff and vegetables......

The man in his 40s revealed his true feelings, which made Su Cheng also sigh. There are too many factories producing sucker rods in the country, and the township enterprises that made money in the early years have also begun to enter this field in a big way, and the state-owned factories that have been pressed are out of breath. ”

"Yes, yes. We are willing to take Dahua Industry as the leader. Dong Jianjiang's lips trembled. Although they can also produce high-frequency quenched sucker rods, the high cost is not profitable at all, but a large number of ordinary sucker rods, which may bring the factory back to life. He used to think that the era of ordinary sucker rods was over, but Dahua Industrial's anti-eccentric wear system made him see a touch of light.

Xue Jie was still immersed in disappointment and was about to leave quietly, but the oilfield leaders who came with him stood still and asked: "Comrade Su, we also want to order a batch of anti-deflection systems in Daqing Oilfield, can your production capacity keep up?"

Xue Jie's eyes suddenly widened, like a comic book character.
