Chapter 67: Well Logging Technology

  A leader's jokes often have some truth to them.

  Su Cheng, as a party involved, also sensed that Nai He didn't want to be bothered with this matter, so he pretended not to have heard about it and focused on production and chatting with friends.

  In just a few days, the anti-drift system was completed, and Su Cheng confidently installed it on the self-priming well in Binan.

  This well can be said to be a wind vane for private oil fields. As soon as the workers start working, the oil bosses will come over to watch.

  The most enthusiastic one was the tall boss Tan Mao, whose oil well was nearby. He smiled and asked: "Boss Su, what are you changing?" "Anti-deviation grinding system. Pipe rod reduction grinding sleeve, straightening device and weight-increasing rod." Su Cheng listed them like a family treasure, and then complained: "The equipment we rent is all twenty years old, and it doesn't have any anti-deviation grinding treatment at all. The oil extraction rod that costs hundreds of yuan can become like this after using it for just one month." He pointed to a section of the oil extraction rod laid flat by the workers, on which obvious corrosion and wear marks could be seen.

  Tan Maogan felt the same way: "It's not, we bought oil extraction rods from the oil field, all of which are old goods. Old Su has a good relationship and uses 20-year-old old goods. Look at mine, B80 from 30 years ago, it's simply deadly."

  Thirty years ago, it was already the 1950s. Su Cheng joked: "Imports from the Soviet Union are not bad, can be collected in the future."

  Tan Maohaha laughed loudly, intentionally drawing closer and said: "This oil extraction rod, we have a saying, new three months old three months, patching up again for three months. You see, calculated that way, the depreciation fee is only 100 yuan per month." "1 ton of oil also costs more than 40 cents, stopping production isn't worth it." Su Cheng lost his smile and pointed at the replaced flange, saying: "The whole set of equipment is 2000 yuan, guaranteed to be used for three years, all replaced within two hours, very convenient."

  Lai Ruo Xiang finally understood why Su Cheng insisted on paying 2000 yuan to the factory after guiding the workers to install it. It turned out that he had long planned to sell something worth 300-400 yuan for 2000 yuan.

  Thinking of this, Li Jianxiang smiled secretly: those oil bosses are all cunning like ghosts, how can they be so easily deceived?

  Unexpectedly, Tan Mao looked at it for a while and decided: "Su boss, I'll take three sets." "Okay, the first batch will arrive next month and I'll give you a discount."

  Tan Mao looked at it happily for a while and left.

  Su Cheng saw off the guests a few steps away and then turned back to Li Ruo Xiang, who was raising an eyebrow and winking at him, saying: "Old Lin, are you suffocating?"

  "His pants were all wet." Old Lin stared with wide eyes and asked, "Director Su, that tall oil boss, did he buy our equipment just because of your face?" "What do you think?" "If I were him, I would have bought one set out of respect. Three sets for 6,000 yuan at a 9% discount is still quite expensive. Director Su is really black-hearted." Li Rensheng's thumb was raised in praise, but then he suddenly realized: "With the discount, we made 600 yuan less!" The people in front all burst out laughing.

  Su Cheng said with a smile: "More than 5,000, which is about 10 days' profit."

  "You heard him say that it would take three months to repair and maintain, which is impossible. You are in charge of installation, this oil rod is worn out and damaged, if you want to repair it, it will be more troublesome and the damage will be faster. What if the rod breaks, and the salvage operation takes several days? In three years, the downtime caused by uneven wear and tear would be enough for him to buy new equipment. Moreover, the higher the output, the more losses during downtime."

  Li Huanxiang nodded slightly and said in agreement: "In that case, even if we sell it for 10,000 yuan, there should be someone who wants it, right?" The workers in front of him dispersed like birds and beasts.

  Not long after, two oil bosses who came to visit were respectively sold two anti-deviation grinding systems, and then the self-injection well in Su City resumed operation.

  Afterwards, Su Cheng and others went to Nan Er Zhuang to replace the anti-friction grinding system.

  Upon arrival, only three people were seen sitting under the shade of a tree with large sheets of paper and thick stacks of documents in front of them. From time to time, they would run back and forth to the oil well, where several testing instruments seemed to be placed.

  Li Huanxiang and others rushed over and stopped the oil pump, only then did the three people notice the grayish car team, put down the drawings and walked over to greet them.

  Director Yang followed, whispering in Su Cheng's ear: "It's Qin Shihui, the deputy director of the Oil Drilling Research Institute, a high-ranking official."

  Su Cheng nodded slightly.

  Qin Shiwei walked over quickly. He was a burly man who, on the surface, showed no signs of being a researcher. In fact, his muscular physique gave people the feeling that he could lift an oil extractor.

  He didn't notice what Li Rengan and others were doing, and asked in a loud and rude tone: "Which unit are you from?" Although people in the 80s would ask questions like this, Qin Shengwei's physique easily made Su Cheng think of Hong Kong movie scenes: "Who is your boss?", actually, the meaning of the question was almost the same.

  Director Yang's dog legs crowded up, and he said: "We are from Dahua Industrial Co., Ltd. This is our Director Su." Qin Shihui responded with an "oh" and then asked: "These three wells, is this Director Su the one who figured out low-resistance wells?"

  Director Yang had an expression of "you didn't know" and introduced the two people again.

  Qin Shiwai patiently waited for him to finish speaking, and directly asked: "Director Su, how do you detect and determine the high water cut of a deep well with high shut-in pressure?"

  This sentence suddenly gave Su City an exam-like feeling.

  Looking at Qin Shihui's powerful appearance, it was as if he were a professional who specialized in producing instructor-type robots in a factory.

  Su Cheng's head spun around, and he replied: "The logging technology for low-resistivity wells, I don't know much about it. Theoretically, there are mainly four methods: the quadrature parameter limit method, the combination entropy method, the differential analysis method, the natural potential difference method, and the lateral comparison method..." Several young researchers were taken aback, their necks straightening in surprise: "This is what you call not knowing much!" Qin Shihui's face also broke into a smile. Seeing that Su Cheng understood so many cutting-edge research contents in the field of oil extraction, his enthusiasm for learning surged, and he asked loudly: "This natural potential difference method, isn't it resistivity logging? But we've tried it too, and there's a big gap between our numerical curves and the foreign research results."

  "That's the influence of mud invasion, and it may also be mineralization. Our oil field has many lithological reservoirs, so this method can't be used."

  Vice President Qin was taken aback for a moment, then suddenly overjoyed, and the researcher behind him hastily pulled out a notebook. He even reverently brought over a chair, inviting Su Cheng to sit down and speak.

  Su Cheng did not mean to conceal anything. These are purely academic theories, although they can be applied to find low-potential wells, but that is still a massive undertaking.

  At that time, there were three fellow students who did the graduation design together with a experienced instructor, and it took three months to measure and recover one oil well. The real value of this technology lies in the popularization of instruments after guiding the front-line work. It is not necessary to wait until the oil well stops production before re-drilling, and at least a few thousand of the 20,000 oil wells in the oil field can increase production to varying degrees through this method.

  Without the advantage of foresight, Su City wouldn't even bother to sort through the thousands of abandoned oil wells in the Victory Oil Field for the sake of a few dozen tons of crude oil per day.

  The benefits in it are scalable, Su Cheng thinks, and might as well be given to the country.

  Under the guidance of this idea, Qin Shihuang gained great benefits and didn't move a single finger even when his hand was sore from writing.

  His attitude also stimulated Su City. Compared to Dean Qian's technical bureaucracy, Qin Shiwei, a purely technical person, is obviously more likable.

  Two hours passed in the blink of an eye.

  Li Xiang and others worked together at the same time and replaced the anti-deviation grinding system of three oil wells. Su Cheng hurriedly bid farewell and left.

  Qin Shiwei's problem is getting deeper and deeper, he can barely hold on anymore.

  The petroleum industry and petroleum research are applied, 21st-century students learn the cutting-edge technology of the eighties and nineties. However, their foundation is thin, they can talk casually, but two hours might be the limit.

  Qin Shiwai suddenly realized what they had just done and asked a couple of questions, then quickly grabbed Su Cheng and said: "Director Su, aren't you planning to promote this anti-bias grinding system?"

  "Of course, our factory produces them for sale."

  "Have you done the test?" "The test?"

  Qin Shiwei smiled warmly and said, "The test is through our Drilling and Oil Research Institute's testing. We will issue a certificate of appraisal using quantifiable data to assess the practicality of your equipment. Let's go to the research institute on the way."

  Su Cheng looked at Li Ruo Xiang.

  The latter smiled twice before saying: "Director Qin, our anti-bias grinding system has been submitted for testing and is in the queue."

  "These kids are so inefficient, let's go and hurry them up." Qin Shiwei said as he lifted Su Cheng onto the car.

  Su Cheng sighed and didn't wait for Qin Shihui to ask, he himself started talking: "Low-resistance well, equipment is relatively critical..."

  He simply said everything he knew about low-resistance wells, and as for Qin Shiwei's inquiry, he completely ignored it.

  It's quite smooth going this way.

  At the Drilling and Oil Recovery Research Institute, due to Director Qin's face, the staff immediately pulled out the application for the anti-deviation grinding system, and put a specially-made steel frame on the assault equipment, placing it in a simulated downhole environment for physical testing.

  Once two researchers were in place, the steel frame began spinning wildly.

  That action easily makes Su City think of American rodeo competitions.

  Qin Shiwei sighed beside him: "Now the conditions are better, I had an experience before, to test the wear resistance of a workpiece, I sat there, holding the workpiece with my hand and grinding it, grinding once, counting one time: grinding once, counting one time...""How many times did you count?" "1,170,077, I still remember now."

  Li Xiang's eyes widened in admiration: "Your muscles are so developed, it must be the result of this." "The test results are out." The researcher in charge filled in a few numbers and handed them over.

  Qin Shiwai took over and glanced at it casually, letting out a "hmm" sound, then looked at it twice from top to bottom and from bottom to top, as if he had seen something unbelievable.
