In order to shorten the technical gap with foreign benchmarking companies, fully realize the localization of large-diameter oil pipelines, and solve the technical problems of domestic unconventional oil and gas field development, the Litong Technology Petroleum Pipeline R&D team has increased its technical research efforts and focused on the high-speed transportation of wear materials during the mining process. , Super-corrosive acidification fracturing fluid, high-pressure mud during completion operations and other special fluid media difficulties and key points to carry out research, collate and analyze existing data, establish research and development directions, after repeated discussions, tests, and multiple optimizations Material formula and technical process, breaking through a number of key core technologies of "jamming", and finally developed and produced ultra-high pressure super wear-resistant acid fracturing hose, including 3" 138MPa (20000 psi) super wear-resistant acid fracturing hose technology and performance It has surpassed foreign benchmarking companies and has led the technology of large-diameter oil pipelines. At present, Litong Technology's 3"20000psi, 4"15000psi, 5"15000psi series of super wear-resistant acid fracturing pipelines have been successfully developed and tested, marking China's fracturing The pipeline technology field successfully broke through the "speed limit" and officially ranked among the top in the world.
