The time goes back to the summer of 2014, when zhang xander, with his passion for geological exploration, arrived at the 40186 wells team as an intern drilling worker, just in time for a horizontal well construction in the eastern sector, the sound of the rigs was sorely disemboweled, the heat on the rig was 38. 9 degrees high, and the heat was pouring out of the rig, and the blood bubble was sharpened from his palms when he first worked。
He saw his predicament and handed him a pair of tarp gloves and smiled and said, "the driller's skill is to grind it out of his hand and to drill it out of his heart." he never forgot that. In order to be able to handle the operation as quickly as possible, during the day he learns how to pliers and drills, and at night he eats in his dorm. Specialized books, such as " foundations of well drilling works " , have been kept in small books with equipment parameters and well-recognised protocols, with them, and can be looked over at at any time。
In one of the projects, a well leaked and the sound of the mud pump suddenly suffocated, the masters immediately deployed the mud, and he moved the leak material and ran dozens of times from the mud hut to the slurry canister until three o'clock in the morning. The hard fight has taught him that drilling is a physical, technical and responsible battle, and that only by being more technical, safer and more serious to each inch can the bottom line be maintained and the security line firmly secured. Thanks to this effort, zhang zhang zhanda's performance in his post was unanimously recognized by the leadership。
In 2015, he was promoted from a first-line driller to a technician with solid merit and theoretical knowledge. From an operational to a technical position, he knew that the burden on his shoulders was heavier: not only he could do it himself, but also with everyone. In order to compensate for the lack of theoretical knowledge, he was given a certificate of qualification as a junior engineer for drilling using the amateur system for specialized courses such as " hydrotechnologies " and " hydrocarbon engineering " 。
In 2017, after two years of study and sanctification, zhang xuandar has demonstrated his professionalism as a technician. During the year, zhang zhang dynasty came up with a critical breakthrough in his career, carrying out the work of 16 directed wells on his own, in a complex geological structure, with a highly leaning layer, with frequent changes in rocky nature, and with extremely difficult construction efforts。
In the face of the challenge, zhang was quick to develop the construction programme: he had repeatedly analysed the information on the adjacent wells prior to construction, taking into account the characteristics of the floor and pre-judged risk points; the drilling parameters had been adjusted in a timely manner during the construction to optimize the type of drill. In teamwork, he efficiently coordinates the various positions of mud and orientation and strictly controls the quality and safety clearances so that the construction progress and quality of each well are in line with the requirements of a。
During the year, he handed over an eye-opener report card: 16 directed wells were fully compliant, with a 100 per cent quality pass and a total improvement of 41229 metres. His technical competence and professionalism have been highly recognized by both parties. He understood that the value of technicians was “to speak with data for effectiveness”. This year, he was awarded an outstanding annual trade union activist in the coal field geological system of the province of shaanxi。
In 2019, zhang sundar carried out a major drilling project — the technical director of the hubei arbitrator well, faced with new blocks and unknown underground conditions. In his capacity as technical officer, he led the team in conducting repeated research and design, insulating on-site security measures, refining statistical drills, screws, etc., and constantly optimizing drilling parameters, which culminated in the successful completion of the construction mission。
This year, he was honoured by the company's good security officers, advanced individuals and others, and proudly joined the communist party of china, standing under the banner of the red party, making a solemn declaration in which he firmly believed that technology was the hard-on weapon of a well-drilling man, that party membership was the spiritual flag that he had maintained throughout his life, that he had to carry out his duties as a member of the party, and that he was at the forefront of energy exploration。
In 2020, zhang xuanda took up the position of chief of training college. From management techniques to management teams, the challenges he faces are all-encompassing. At the beginning of his term of office, he had spent half a month carrying out a full survey of the well liner equipment, the implementation of protocols, the rectification of various safety hazards, and the innovative creation of a security control mechanism combining daily inspection, weekly screening and monthly analysis, which placed security responsibilities on every position and every employee。
In 2022, during the construction of the changqing oil field oil exploration plant, faced with serious challenges in terms of schedule and tasks, zhang was quick to pursue the process optimization method: pre-positioning the drilling, securing and surveying of wells and significantly reducing the construction cycle。
During that time, he worked hard every day, staring at the links at every link, and sometimes in order to calculate a key parameter, he spent hours on the rig first. Ultimately, they were able to complete each well ahead of schedule and were of excellent quality, and the team was commended by the a。
Zhang xuan ta has learned that “the team is not strong and the team leader is critical”. He introduced a “party member responsibility area” system, whereby party cadres took the lead in capturing safe and skilled apprentices, organized a “well team skill-building” exercise, and developed a skilled and highly skilled workforce through a “theory test + practical examination”。
Under his leadership, in 2023, the team received a first-class group award in the company's safe production month, and he was personally awarded the company's best communist and trade union activist。
In 2024, zhang xuda officially assumed the position of chief of team 40185 wells. In the course of the year, he presented the management philosophy of “party leadership, security casting, innovation-driven”, leading the well team to launch an impact on the objectives of the “first-level safety standardization team”。
They have integrated “party-building + security” in depth, set up “party-member safety demonstration posts” and conducted “party-member-friendly” activities, allowing party members to be at the forefront of hazard screening and risk management. He took the lead in developing the standardized manual for the safety of well teams, standardizing and visualizing processes such as equipment operations, on-site management and emergency disposal, and organizing staff exchanges on safety incidents, drawing attention to safety with the example of those around them. In that year, he led the wells team to be rated as the “advanced collective for safe production in 2024” of the coal geology group, and he was once again personally rated as a good communist and a good trade union activist in 2024 of the company。
In 2025, zhang xuan da led the 40185 wells team and faced complex geological conditions and demanding construction requirements, insisting on technical lead and precision, efficiently completing three large slope wells and six conventional wells, successfully deconstructing technical difficulties such as trajectories control, construction risk control and high-quality delivery of all works。
In the course of the construction, he insisted on a technical lead, organized teams to analyse well-site data in depth, optimized the construction programme and effectively addressed the difficult and high-risk problems of controlling the large slope well tracks. The team achieved significant improvements in construction efficiency through enhanced equipment maintenance, rigorous process interfaces and the introduction of “detailed, standardized” operations, resulting in a high level of praise for the quality of the work. As a business backbone, he represented the group in the 13th national mineral rescue skills competition and received several triple awards with teams based on solid theory and hard skills; as chief of the wells, he led the 40185 wells team in its efforts to advance standardization, and was successfully awarded the title of "standarding the first level security team" to set the bar for company standardization management。
In that year, zhang xuan was awarded several pounds of honour, first and foremost by the “good communist” group, then by the oil and gas company in 2025, and then by the gold and gas union in 2025。
As a member of the communist party, zhang xuanda kept in mind that “a party member is a flag”. He took the lead in the rush: in 2023, heavy rains hit the wells team during the construction work, he reinforced the flood canals overnight with a party member's commando team, transferred equipment and avoided significant losses; in 2024, when new employees wanted to resign because they were not fit for the wells team life, he took the initiative to talk to new employees, with familiar work processes to help solve the hardship, and now the new employees are the technical cadre of the wells team。
Today, zhang xuan da is still at the line of drilling wells, sending the teacher's teachings to every young employee, leading all members of the 40185 well team to deep-drive technological innovation, to secure the safety line, to build hard teams, to march forward on the journey of energy, to drill more high-quality wells and efficient wells with hard work and strength, and to contribute fully to the high-quality development of the coalfield geological oil and gas exploration industry
