Daqing Oilfield 1205 Drilling Team Took The Lead in Breaking Through 25,000 Meters in The Gulong Unconventional Block

In the middle of winter in the North, dripping water turns into ice. Drilling workers in the Daqing Oilfield overcame the huge difficulties brought by the extremely cold weather to production and life, drilling day and night, and acted as the "backbone" to ensure energy security and supply. On November 28, as the tripping bit left the drilling floor, the Daqing Oilfield 1205 drilling team was about to conduct logging operations in the GY25-Q9-H5 well.

Since the beginning of this year, the 1205 drilling team has taken the implementation of the "three major events" as its own responsibility, aiming at the goal of "one stability, three increases and two improvements", focusing on the single-well safety speed-up and efficiency project, insisting on seeking benefits from safety and environmental protection, and seeking benefits from lean management. We carefully organized drilling production, continuously improved and innovated drilling processes and measures, shortened the drilling cycle, and reduced drilling operation costs. We completed 5 horizontal wells with high quality in the Gulong block, and the annual footage exceeded 25,476 meters for the first time. This is also the first time for this "benchmark team" It broke through the 25,000-meter mark in this block for the second time.

We will tackle key technical problems and promote speed and efficiency. The team is guided by the integration of engineering geology and gives full play to speed-up templates and expert wisdom. The well team has close contact with the project department and relevant departments of the company. The film director, well director and other technical personnel monitor on-site to provide technology and technical support for the efficient construction of the well. "Comprehensive" support for production, safety, and equipment. In line with the concept of "everything revolves around the wellbore", we adhere to the technical model of "one well, one strategy, one section". Before drilling, we refer to the construction data of adjacent wells, select drill bits and drill tool combinations, optimize drilling parameters, and target wells during drilling. Conduct in-depth analysis and research on hole trajectory control, formation dip angle changes, wellbore cleaning, etc., conscientiously implement the emergency warning system, strictly implement the "three majors and two highs" aggressive drilling, work together to overcome difficulties, and achieve outstanding results in improving the speed and efficiency of optimal and fast drilling.

Process supervision and building a safety line of defense. Carry out various forms of safety education, insist on organizing and studying safety and environmental protection accident cases, and guide all employees to firmly establish the "red line" awareness of safety production. At the same time, we make full use of engineering geology integration meetings to extend safety management from "ground" to "underground" and integrate positions, integrate into key links, and consolidate responsibilities layer by layer. Captain Zhang Jing, branch secretary Duan Yongjian, deputy captains Wang Lei, Zhao Shizhe, and Gao Chen took turns stationed in the well, taking the lead in strengthening shift inspections and mid-shift inspections, identifying problems in a timely manner, and achieving "zero tolerance for problems and strict implementation of rectifications", especially In terms of well control management, we continue to increase efforts to identify hidden dangers in well control equipment and strengthen the study and judgment of underground operation risks, laying a solid foundation for the efficient construction of this well and providing a strong guarantee for the efficient construction of this well.

Party building leads the way and stimulates endogenous motivation. Taking the company's implementation of the "red grid" governance model as an opportunity, the grid is refined to clarify responsibilities, so that the branch can lead grassroots governance with a clearer interface, clearer tasks, and more outstanding effectiveness. A team of three members including Party members of the Management Chuangyou Grid, repair and construction, used on-site materials to make a self-made combined tool device that can quickly lift the cylinder liner, further reducing the labor intensity of employees, shortening the repair time of the large pump, and ensuring the conversion of two to three openings. Goes smoothly. All party members base themselves on their posts and take on their responsibilities, driving all employees to work together to overcome difficulties, further stimulating the enthusiasm of officers for entrepreneurship, and creating a strong atmosphere in which "party members take the lead in creating excellence, the masses follow up and compete for excellence, and everyone strives to be a drilling craftsman." Inject red kinetic energy into the team's harmony, stability, and safe and efficient completion of production tasks.
