The high-end equipment manufacturing industry is an important part of strategic emerging industries. The series of reports "Accelerating the Formation of New Quality Productivity Front-line Visit", today into a drill bit manufacturer in Cangzhou Hejian, their oil and gas exploration "diamond drill", is under the blessing of high-tech "intelligent navigation", to more than 10,000 meters deep march.
Deep in the underground of the Sichuan Basin, the Pengshen 6 well in the southwest oil and gas field of PetroChina has continuously overcome world-class exploration and development problems such as ultra-deep, ultra-high temperature and ultra-high pressure, and has broken through 9,026 meters in one fell swoop, setting a new record for the deepest vertical well in Asia. The drill bit that helped drill out of this "underground Everest" was born in Hejian City, Hebei Province.
Hebei Radio and Television reporter Gu Lin:
The completion bit of Well Pengshen 6 uses the 6-inch PDC bit next to me. Despite its small size but incomparably hard, it is specially designed with more than 50 teeth composed of this polycrystalline diamond, which can withstand all kinds of complex conditions in the underground, overcome thousands of degrees of heat, and gnaw hard rock.
As one of the most high-end tools in the oil and gas drilling industry, the quality of the drill bit directly affects the cost and efficiency of drilling. Although the company's drill bits are already excellent for grinding and impact resistance, they are now anxious to think about how to make the drill bits stronger.
Zhou Xuejun, general manager of Chengdu Branch of Cangzhou Great Drill Bit Co., Ltd.:
From our onshore point of view, it is from more than 6,000 meters of deep wells, ultra-deep wells to the current implementation of 10,000 meters of deep wells, the depth of the well is getting deeper and deeper, the formation is more and more complex, so these complex formations and working conditions are also higher and higher requirements for our drill bits.
10,000-meter deep oil and gas drilling is a super project in the field of global oil and gas exploration, and it is also a highland for scientific research of many oil and gas equipment manufacturing enterprises. How does "Diamond Diamond" serve the super project, in addition to the conventional update of the design structure and optimization of the sintering process, Glitter has also added a highly difficult carcass material research and development.
Zhou Xuejun, general manager of Chengdu Branch of Cangzhou Great Drill Bit Co., Ltd.:
This test stick is the third generation (carcass powder) test stick that we are testing now, and its performance exceeds 50% of our industry standard indicators. Its flexural strength reaches more than 900 megapascals, while some have been on 1000 megapascals, our material it is able to adapt to some formations like granite, it has higher abrasion resistance in addition to its high strength. After this round of testing, our next step is to do the test of real drill bits.
To march deeper, the drill bit not only needs a hard shell, but also a smart brain. In the complex drilling environment, how to make the drill bit accurate and accurate, and accurately find the location of oil and gas burial is a cutting-edge topic in industry research. This has also become the direction of Great Sprint to the head of the industry and achieve a leap in productivity.
Just as Gretel was setting his sights on the forefront, the Hejian City Government also brought exciting news. In November 2020, the Hejian Laboratory of the Beijing Key Laboratory of High Dynamic Navigation Technology officially landed in Hejian. A scientific research team specializing in the research and development of downhole engineering parameter measurement technology and torsion impactor has successfully developed a set of engineering parameter measurement system that fills the gap in China, and installs "intelligent navigation" for the drill bit.
Yang Zhenpeng, researcher of Beijing Key Laboratory of High Dynamic Navigation Technology:
Using our self-developed equipment to collect downhole parameters, and then analyze downhole data to reveal potential downhole risks, provide reasonable engineering guidance for the surface, improve the safety factor, and reduce economic losses.
The R&D and testing of this technology has given Great the confidence to seize the commanding heights of future development, and also allowed Hejian City to see broad prospects. At present, Great is jointly conducting technical tests with this scientific research team, and Hejian City is breaking the ice with "diamond drills" to encourage leading enterprises to better play the role of the main chain and drive more oil drilling equipment manufacturers to accelerate the release of new momentum for development.
Li Chunyan, general manager of Cangzhou Great Drill Bit Co., Ltd.:
In the future, our Grute products will be further extended to the direction of high intelligence, like our intelligent drill bits, and constantly carry out the transformation, upgrading and innovation of traditional industries in new materials, new technologies, new processes, etc., so as to accelerate the formation of new quality productivity.
