Tuha Oilfield Breaks The 1,000-meter Mark For The First Time

In the Kangtan 1 block of the Fukang Sag in the Junggar Basin, the Kangtan 1-W-2H well, which was responsible for increasing the drilling speed by the Tuha Oilfield Oil Production Technology Research Institute of PetroChina, successfully achieved a new breakthrough in drilling technology.

During the drilling process of the 311 mm borehole, the daily footage of the well reached 1,005 meters, breaking the 1,000-meter mark for the first time and setting a record in the history of the Tuha Oilfield, laying a solid foundation for the efficient completion of the subsequent speed-increasing tasks of this well.

Since the first quarter, the Oil Production Technology Research Institute has implemented the spirit of the two sessions of the oil field company, firmly grasped the general requirements for efficient oil field exploration, adhered to technological innovation, and created a source of scientific research and development as the goal, and focused on "short board" technical research and "forward-looking" Technological innovation is the main line to overcome the problems of slow machine speed and low footage, and comprehensively improve the engineering technology supply capacity and support level.

Behind this breakthrough in daily footage of well Kangtan 1-W-2H is the unremitting efforts and fundamental changes made by the Kangtan 1 block drilling speed improvement research team of the Oil Production Institute from the management and technical levels.

In the drilling speed-increasing plan, technical personnel coordinated the drilling process design, highlighted the pertinence, effectiveness, and economy of the speed-increasing plan, strictly implemented the "three strict prohibitions and one avoidance" prohibition requirements, and continuously improved the quality of the speed-increasing plan. According to the properties of the formation, special speed-increasing tools were studied and applied, and drilling parameters were comprehensively strengthened.

During the accelerated construction process, a high-quality professional technical service team was established to conduct real-time training for technical personnel. Experts kept an eye on the site and provided a variety of service forms to continuously improve the quality and efficiency of on-site services. The technical team ensures the efficiency and safety of drilling operations through detailed geological analysis and scientific drilling planning. At the same time, we continue to refine the technical plan of "one strategy for one well, one strategy for each section, and one strategy for each trip", promote the implementation of the speed-up plan, conduct personalized research and selection of drill bits according to different well sections, optimize the drilling tool combination, and strengthen drilling parameters to effectively improve Improve drilling speed and efficiency.

"The daily footage of Well Kangtan 1-W-2H exceeds 1,000, which not only provides a valuable learning curve and experience for the subsequent development of Tuha Oilfield in this block, but also sets a new technical benchmark in the field of drilling engineering technology." Wang Pinde, the person in charge of the drilling site, said.
