In the relentless pursuit of energy resources, the oil and gas industry often ventures into the most challenging and extreme environments on Earth. Ultra-deep wells, characterized by high temperatures and high pressures, push the limits of conventional logging technologies. However, a groundbreaking development by researchers at the 22nd Research Institute of China Electronics Technology Group Corporation in Xinxiang, Henan, is set to revolutionize the way we explore these treacherous terrains.
Dr. Sun Zhiyuan, the lead author of a study published in Cejing jishu, which translates to “Instrumentation Technology,” has spearheaded the creation of a high-temperature direct push storage logging system. This innovative technology addresses the severe challenges posed by complex well conditions, such as well leakage, overflow, and large displacement horizontal wells.
Traditional logging methods often falter in the face of such extreme environments, but Dr. Sun’s system leverages drilling tool direct push construction technology to complete logging operations seamlessly. “The key to our success lies in the standardization, digitization, and modular circuit design,” Dr. Sun explained. “These elements, combined with advanced insulation techniques, ensure the reliable operation of the measurement circuit in high-temperature environments.”
The system’s design is meticulously detailed, addressing every component from the pressure-bearing steel cylinder to the battery short section. The researchers have also conducted thorough theoretical calculations to determine the critical pressure values for sinusoidal buckling of instrument strings in different wellbore sizes. This analysis provides crucial technical support for risk prevention and control in logging construction.
The implications for the energy sector are profound. As oil and gas companies increasingly turn to ultra-deep wells to meet global energy demands, the need for reliable and efficient logging technologies becomes paramount. Dr. Sun’s high-temperature direct push storage logging system offers a robust solution, capable of withstanding the harshest conditions and providing accurate data essential for successful exploration.
Performance tests, including high temperature and high pressure, tensile and compressive strength, and insulation bottle temperature resistance, have proven the system’s efficacy. Field applications in ultra-deep oil and gas fields and complex geological structures have further validated its potential. “This system not only solves the logging problems of ultra-deep high-temperature and high-pressure wells but also provides strong technical support for deep oil and gas exploration logging,” Dr. Sun asserted.
The development of this logging system marks a significant milestone in the energy sector. As the industry continues to push the boundaries of exploration, technologies like Dr. Sun’s will be instrumental in unlocking new reserves and ensuring the sustainable supply of energy resources. The research, published in the journal Instrumentation Technology, underscores the importance of innovation in overcoming the challenges of ultra-deep well exploration. As we look to the future, the high-temperature direct push storage logging system stands as a testament to human ingenuity and the relentless pursuit of energy security.
