Gao Wenqing: Chief of the drilling rig of the Fourth Hydrological Engineering Geology Brigade of Hebei Provincial Bureau of Geology and Mineral Exploration and Development. Stick to the drilling line for 26 years, and spend more than half a year in field operation. He is determined to forge ahead, innovate independently and make breakthroughs in the drilling industry. He won the National Bronze Award in the first National Geological Exploration and Drilling Professional Skills Competition, Hydrological Well Driller Competition. Obtained Hebei Provincial Technical Expert, Hebei Provincial Craftsman, Hebei Provincial Model Worker, Hebei Provincial outstanding contribution technician and a series of honors. Two utility model patents were obtained.
In Longhua County, Chengde City in April, the lowest temperature is still below zero. The construction site of a geothermal well in Qijia Town has machinery and equipment around the clock. Due to year-round field work, Gao Wenqing's skin is dark and rough. When it comes to the drilling business he loves, he always spout eloquent speeches.
"It's amazing to see the field drilling rig and the ore taken out by the workers from the ground for the first time!" In 1977, Gao Wenqing was born in a rural family in Renqiu City. When he was 10 years old, he first followed his mother to the field operation site where his father worked, and was immediately attracted by the sight. He is determined to be a geologist like his father People, the seeds of dreams take root and sprout in their hearts.
In 1994, Gao Wenqing, who graduated from junior high school, gave up studying in senior high school to go to university and chose to apply for the major of hydrology and water well drilling in the Geotechnical School of Hebei Bureau of Geology and Mineral Resources. After graduating in 1997, Gao Wenqing was assigned to work in the fourth hydrological team. Since his employment, Gao Wenqing has adhered to the spirit of craftsmanship, studied hard and studied deeply in his own post, and has the courage to innovate and be the first to constantly improve his technical skills, showing his dedication and dedication to drilling with a word of "drilling" Explore life.
Gao Wenqing, a driller, a field worker, a mud worker, a derrickman, and every position on the rig I've done it all. He knew that to become an excellent driller, he had to master mud A series of drilling construction technologies such as slurry allocation, bit selection, drilling tool allocation, drilling parameter design, etc. He believes that the more work you do, the more you learn. Therefore, no matter where he is, he always struggles to do dirty work. "When drilling, sometimes the mud gushes out with the drill, and it's too late to dodge. Look at me, big guy, and I'll look at you, showing my happy white teeth." Gao Wenqing never felt hard during field work, but enjoyed it. The earth has endless secrets to explore. He likes listening to the old drillers tell stories about their work. These stories are like It opened the door for him to understand the world.
After working, Gao Wenqing gradually found that the knowledge he learned in school was far from meeting the actual needs. Therefore, he learned experience and operation with his teachers in the daytime, and taught himself new knowledge and technology in his spare time. Driven by him, several studious workers spontaneously formed a study group. New and old workmates study together and often "learn from each other". Skills competition enables more knowledge from books to be transformed into "skilled work" in actual work. Gao Wenqing, who worked hard, also became the youngest class in the team from a new recruit Long, the workmates vied with him for advice.
In the summer of 2001, the Provincial Bureau of Geology and Mineral Resources issued a notice that young employees of field geological units could apply for Hebei University of Geology and Workers for further education with pay. This is an excellent opportunity to change jobs and get away from the harsh environment in the wild. At the same time, five people who graduated from the fourth hydrological team and were assigned to the fourth hydrological team with Gao Wenqing left three at a time. However, this exam coincided with the heavy drilling production task, and Gao Wenqing resolutely gave up the opportunity for further education. He knew very well that, My dream is to be on a field drilling rig.
With love for work, for only five years, the deputy squad leader, squad leader and deputy captain, Captain, Gao Wenqing keeps improving. The workmates called him "super driller" and "captain Niu".
"As a driller, when he is on the ground, his eyes have already gone underground with the sound of the drill bit." Through years of accumulation and experience, Gao Wenqing has developed a set of skills of listening to sound and recognizing things in continuous dialogue with the earth. He can quickly identify the sound from the drill In addition to underground drilling, the best drilling plan can be quickly formulated by interpreting the earth code.
In 2008, when constructing in a coastal area of Tianjin, the conventional bit footage was slow and the effect of repeated replacement was poor. Gao Wenqing's investigation found that the viscoplastic stratum in the coastal area is the cause of the situation. He assembled and welded the big tooth non self-cleaning drill bit by himself, greatly improving the drilling Advance speed and well completion quality. The construction period of a single well is ten days ahead of schedule, and the water yield increases by 15%.
In the process of continuous downward drilling of ultra deep wells, it is necessary to ensure that the upper borehole is intact and does not collapse, and that the rock debris crushed by the bit is smoothly discharged from the bottom of the well. It is also necessary to ensure that the high-speed rotating bit will not be scrapped in advance because of heating, which is achieved by the circulation of mud in the well. Gao Wenqing told reporters that mud is regarded by drillers as the blood and soul of the drilling project. Mud treatment and purification is to improve drilling efficiency and quality The key to.
Most of the drilling projects undertaken by Gao Wenqing are located in the North China Plain. In view of the formation characteristics in this area, Gao Wenqing optimized the drilling tool assembly mode and drilling parameter allocation, improved the single tube coring process, changed the previous direct use of pump pressure coring method, and prevented the mud from directly scouring the core. In several layered standard group projects and exploration projects in the Tertiary and Quaternary fault zones, the core recovery rate reached more than 95% for cohesive soil, 80% for sandy soil It is far beyond the standard.
Drilling work is closely related to people's life. In the spring of 2011, it rained in North China The snow is scarce and the drought is very serious. As the main force of drought relief, Gao Wenqing arrived at the drought relief front line in Gaocheng, Shijiazhuang the next day after receiving the notice. Construction speed of machine led by him It is known as "King of Well" by local villagers because of its fast temperature, large water volume and good water quality.
In 2012, the fourth hydrological team purchased a RT-30 oil rig worth more than 12 million yuan, with Gao Wenqing as the captain. It only took him three years to go from "Xiaobai", who had just come into contact with a large drilling rig, to "an old expert" who had been working safely for nearly 10000 meters. Over the past three years, he has trained 16 young workers, and his apprentice business has grown rapidly. Now there are five qualified for the position of monitor and eight qualified for the position of deputy monitor. The drilling team led by Gao Wenqing has completed 3 wells so far Salt mine exploration wells, 4 geothermal exploration wells, with a safe footage of nearly 30000 meters.
Not only that, Gao Wenqing also insisted on independent innovation. In view of the huge diesel power consumption of RT-30 drilling rig, he formed a team to independently tackle the power transformation scheme, which only consumed In three months, the daily footage cost was reduced from 30000 yuan to 50000 yuan to 6000 yuan.
In recent years, the projects he participated in have not only achieved good economic benefits, but also reduced tail gas pollution, noise pollution and other aspects, demonstrating the outstanding wisdom and home of drillers National feelings. (Contributed by Hebei Federation of Trade Unions)
