Dawan 2 well is one of the key exploration wells in Puguang gas field, a key project of China Petrochemical Company. All employees of Yunguigui 50772DG Drilling Team are extremely proud of undertaking such a national key project and China Petrochemical No.1 Project, and feel that this is a rare opportunity in life for decades. The well was drilled on June 5438+1 October1day, and the designed well depth was 4,950 m on August 12, 2006. After that, the drilling was further deepened according to Party A's requirements, and it was drilled to 5,060.89 m on August 19. This well is ahead of the design drilling cycle by 1.56 rig months. In the process of drilling, new technologies such as air drilling, PDC bit+screw+rotary table combined driving drilling have been adopted successively. In order to speed up the drilling speed of this well and improve the ROP, good results have been achieved. It has set a record for the best PDC bit with the longest drilling time (543:05 hours) and the largest footage (1, 662.66 meters) for a single bit in the marine hard stratum in the south-eastern part of South China. Especially in the southern marine hard stratum, 50m gypsum-salt composite layer which is extremely easy to shrink and expand was drilled for the first time, and the production time reached 95.20%. Such high production efficiency and drilling speed are rare in high-pressure and high-sulfur gas wells in northeast Sichuan under complex geological conditions. In June+10/October, 5438, the drilling team of Northeast Sichuan Exploration Area ranked second among 32 teams and was rated as a high-quality project in the completion acceptance of Party A's project. On June 6th, 2006, 65438+February 6th, 2006, Dawan 2 well achieved a daily production of 586,000 cubic meters of natural gas in the first and second members of Feixianguan Formation, a marine reservoir with a depth of 4,804.4 meters to 4,900 meters, which has a broad exploration prospect.
Deputy Director Tang and Deputy Secretary Yang Chunlin of Yunnan-Guizhou-Guangxi Petroleum Exploration Bureau who participated in the battle personally commanded in the front line. They spend two-thirds of their time organizing production and construction in the front line. Yin Zongguo, manager of Yunnan Guigui Drilling Company No.2, and Li Guangyi, executive deputy commander of Northeast Sichuan Command, have also been rushing about in the field for oil and gas exploration in Northeast Sichuan. The deputy commander appointed by Wu Xin came to fight. Before leaving, his wife generously said to him, "Don't worry, we have everything at home!" " In this way, he came to northeast Sichuan from Shandong to fight. Wei Guyun, the deputy commander, was busy cementing from the well site and didn't go home when passing by the door. In recent years, they moved from Guangxi and Chishui to northeast Sichuan, and successfully completed the drilling construction projects of Well Maoba 3 and Well Dawan 2. They fought together with the drilling team, lived together, and successfully completed various drilling construction tasks assigned by superior leaders.
Some leaders set an example, and all the workers who participated in the war were not to be outdone. Comrade Hu Daocai, deputy chief engineer of the second company, has been running around in the wild all the year round, and has joined the team to drill in Chongqing, Xinjiang, Chengdu and other places. This time, after hearing the news of the Northeast Sichuan Congress, he took the initiative to go to Northeast Sichuan. At work, together with other comrades-in-arms, he worked hard and sweated for organizing drilling equipment. Wang Weidong, the captain of the 50789DG drilling team, finished his homework, but he couldn't let go of dozens of people in the team. Before he recovered, he threw himself into the tense construction of Maoba 4 well. Comrade Zhang Qisheng, the vice captain, is party member. When he learned that the drilling team was in the northeast of Sichuan, he volunteered to fight. He loves his post and the equipment managed by the team. Under his careful care, the equipment used by the team is in good condition of over 98%. Li Mingjun, the captain of 50772 drilling team, has always attached great importance to team building. He cooperated tacitly with several team leaders, organized the construction in strict accordance with the requirements of 28 standards in Northeast Sichuan, and implemented the "three standards" management, which made the production management step by step and was trusted by employees. Yuan Yugang, the instructor of the team, has been recruiting in Chishui and Chongqing for several years. He is good at doing the ideological work of one person and one thing in the work team. In view of the fact that the drilling teams are all young people, with active thoughts and strong plasticity, and easily influenced by the external environment, facing the diversified development of social thoughts, the living space of field drilling is small and the conditions are difficult, which is easy to have a negative impact on young workers, he organized the comrades of the party branch of the team to adopt a hierarchical system to educate the workers on their ideals, beliefs, world outlook and outlook on life. By holding various classes, organizing employees to seriously study the 28 standards of Northeast Sichuan, and carrying out educational activities such as situation and tasks, we can help employees change their concepts and firmly establish the idea of serving the oil and gas production and construction in Northeast Sichuan. In order to ensure the logistics life of front-line workers and do their ideological work well, Yuan Instructor is duty-bound. Qin Hong, deputy director of the general office, went to Kunming for a meeting. After research, it is rare to have such a weekend. She wanted to spend the weekend with her family, but the first-line production was busy. She decided to send her children to school, rushed to the airport with tears in her eyes and flew to the front line of the battle. Huang Li, a female worker, left her starving children behind to go to the northeast of Sichuan to fight, and traveled thousands of miles to the northeast of Sichuan. She turned her yearning for her son into motivation, only to serve the oil industry. Employee Zhang Hong's wife is about to give birth, but in order not to drag down the team. I just decided to devote myself to my busy work. So far, my daughter is almost full moon, and I haven't seen her once. I can only listen to her kind and strange crying on the phone. Thinking of the loneliness of my wife in labor and the birth of my daughter, I failed to do my duty as a good husband and father. Even a person who is five feet tall will shed sad tears. Who says that men don't flick when they have tears, but they haven't reached the sad place yet?
On the afternoon of July 6, 2005, the house of Guo, a villager from Group 9, Village 6, Maoba Town, Xuanhan County, suddenly caught fire. After 1 many hours of heroic fighting, Wu Shizhong, instructor of Yunguigui 50789DG drilling team, finally put out the fire and wrote a touching song of workers and peasants' feelings.
At the end of last year, when the drilling team of 70838DG in Yunnan, Guizhou and Guangxi moved to Laojun 2 Well Field, it was faced with a mountain road of only a few tens of kilometers, and the drilling team of 70838DG carried drilling rig equipment back and forth in the depths of the mountain. The simple highway that has just been opened is rugged, but it happened to catch up with rainy days during the relocation process. Large vehicles lurched on a mountain road that could only accommodate corpses. If you are not careful, you may fall into a ravine tens of meters or even hundreds of meters deep. That scene worried many people. The transportation company of Yunguigui Drilling Company No.2 selected drivers who are skilled in driving, bold and cautious and experienced in relocation to carry out relocation operations.
