Chief Engineer Ellis, an Englishman with extensive experience in exploiting oil fields, pointed to a three-dimensional topographic map on the conference table and said: "This is the Varana Basin, our exploitation point, located in the middle of the basin." The crowd nodded their heads to show their understanding. "We will have some conclusions about the organization of the strata through topographic analysis, remote sensing exploration, and review of relevant data," Ellis said. The crowd looked attentive. Ling Duyu is very interested in the exploitation of oil, is not a simple matter, must be based on the geological structure and changes, to determine the method of drilling, so as not to get half the result with twice the effort. "This is explained by Dr. Weizheng," said Ellis. "Frankly speaking, the Varana Basin is not a good place for drilling," said Dr. Weizheng, a thin American in his forties with a moustache on his lips and a shrewd face. "The ground structure is very complex, dominated by turbidite bodies. The structure has produced high anticlines, multiple faults, and hard strata. Gypsum salt and collapse intervals are densely connected." Ling Duyu listened to the head also big up, this is a very specialized term, teach them this layman confused. Shen Ling said in a deep voice, "What consequences will this have on drilling?" Dr. Wei Wang replied: "Because of the complexity of the formation, many unpredictable situations have been encountered during the drilling process, such as the collapse of the well wall, the occurrence of vicious lost circulation or strong blowout, the difficulty of balancing the formation pressure with the drilling fluid column, the hole shrinkage, and even all kinds of unpredictable accidents.." Another Indian engineer came out and said, "This will make the selection of drill bits frequent and slow down the progress of the project.". Moreover, when the formation collapse accident occurs during drilling, the drilling fluid will be seriously polluted, which will destroy the mechanical operation of the drilling rig. Chief engineer Ellis said: "The biggest problem is that the operation of the well is very difficult. In particular, Dr. Shen Ling specified that the oil well must be able to accommodate a lift to move freely in the well. This will increase the cost to more than 12 times that of an ordinary oil well. Assuming that the depth of the well is not three kilometers as required by Dr. Shen, the situation may be better." "That's why I paid so much money to hire you here," said Shen Ling. "There's no problem with the money. I want to know what the solution is." Ellis said: "There is always a way. We have used our brains on cementing methods. For example, we need to use high-quality sulfonated mud drilling fluid that can withstand high temperatures and prevent sticking, prepare various types of drill bits, adopt the mixed technology of high-angle directional wells, water wells and cluster wells, Narrow aisle rack , and increase the size of casing.." www.xiＡoshuotxＴ.cＯＭ The fourth chapter is the mystery of the Dead Hill (/t/xt | Xiao/Shuo Tian | Tang) When the meeting ended, it was 2:00 p.m. on that day. Ling Duyu and Shen Ling stayed in the conference room and ate their lunch. Eat in silence. The two men were a little depressed, and the mining project seemed to be very difficult. It is precisely the internal and external troubles that are pressing on each other. Ling Duyu said, "I don't think any of them believe that you want to extract oil." Shen Ling said, "When the number in their bank accounts keeps increasing, what else are they doing?" Then he winked and said, "Money makes the mare go. My contract with them States that I only have to follow the instructions and get it out of a deep well. I have no right to ask about anything else." Then he lowered his voice and said, "Shan Na Xing may be the watchman sent by the prince. He just reported for duty three days ago." Ling Duyu sighed and said, "All right!"! Now it's time for you to come clean. Shen Ling smiled and said, "Of course! Of course!"! How dare I hide it from you again. "Go ahead," said Ling Duyu. Shen Ling straightened her face and said, "Have you ever heard of the famous'Mystery of the Dead Hill '?" Ling Duyu said in astonishment, "Of course I have. This is one of the greatest mysteries in human history. What does it have to do with this?" The origin of Indian civilization, from the Indus civilization, represents the two earliest and most important ancient city sites of the Indus River, which are the "Mohenjo-daro" site in Sindh Province of present-day Pakistan and the "Harappa" site in Punjab Province. According to the carbon 14 dating, the two cities should be dated between 2000 and 3000 BC, with an area of about 2. The population is estimated to be 20,000 to 40,000 people. The city has a considerable scale. Shen Ling stood up and said, "Come on!"! Let me show you around. Ling Duyu realized that he was afraid of being overheard, so he hurried out with him. Walking out of the house, the two of them were in high spirits. Make the earth into a confused monsoon, replaced by the sun hanging high, wet plants in the sun, emitting green vitality, fresh breath of plants, blow on the face, as far as the eye can see, the mountains around the distance, hanging a white line from top to bottom, hidden rumbling sound of water, is a waterfall made of rainstorm. "This place is very hot," said Ling Duyu. As far as the eye could see, Shen Ling replied, "This is a basin. It's high all around and sunken in the middle. The heat is not easy to dissipate. Although the sun sets, it's still very hot. Do you know?"? It took more than two months to clear the trees in the mining area. Lingduyu looked at the huge steel frame structure in the center of the camp, the houses far and near, and the dozens of trucks and workers moving around. He sighed and said, "It's really not easy. How long have you been preparing for this?" "Five years," said Shen Ling as if nothing had happened. "Come on," he said. The two men stepped onto the jeep coming from Ling Duyu. Shen Ling drove the jeep all the way out of the camp and parked it on a high hill, which just had a panoramic view of the camp. The two men got out of the car and sat down on a big stone. "How much do you know about Dead Hill?" Asked Shen Ling. Ling Duyu sorted out the materials in his memory and said: "In 1922, the famous Indian archaeologist Banarren discovered the ruins of an ancient city on a desert island in the middle of the Indus River, which is the'Mohenjodaro City ', one of the two ancient civilization sites of the Indus River civilization." "Have you ever studied the age of the ancient city?" Asked Shen Ling. Ling Duyu shook his head. omracking.com
