On 27 september, cover journalists were informed at the china sea oil high-level hydrocarbons technical equipment conference that their autonomous development of a “technology” system had achieved the first three technological breakthroughs globally and that key performance indicators had reached world-class levels, marking a significant leap in high-end oil and gas well detection technology in china's oceans, which would contribute to the efficient development of highly difficult oil and gas, such as deep-water, low-pore seepage, and inject new kinetic energy to upgrade the entire industrial chain of oil and gas exploration。
The “technology” system, a high-end marine oil cable technology developed by china on its own for more than 40 years of marine oil, distributes precision instruments to thousands of metres of wells through cables, using high-precision techniques such as acoustic, electrical, radiological, nuclear and magnetic, to give an accurate picture of the distribution, reserves and quality of the oil and gas reservoir, and is graphically described as the “flaming eye gold hole” that clears the oil and gas reservoir in extreme circumstances。
On 14 march 2024, the uganda oil technology project team carried out a cable well survey project on the gamma spectrum, cross-polled acoustic waves, electrical resistance, radioactivity and pressure sampling at the tilenga project in dodal. (pages for interviewees)
It is understood that among the new generation of industrial equipment for the “twilight” system, three innovative global innovations were launched: high-temperature high-voltage rotor wall cores, heart sample integration and back array density。
Among them, the high-temperature high-pressure rotation wall core, also known as the “small shields”, is the only instrument in the world that can achieve the extraction of large diameter layers of cores in small boreholes and is decisive for the evaluation of complex geology。
The integrated surveyor for cardiac sampling, a revolutionary technology in the field of detection of wells for almost two decades, has been able to achieve a sub-well acquisition of samples of three types of oil and gas, and has resolved the difficulties of exploration operations in complex oil and gas fields, such as low-intensity seepage reservoirs, carbonate rock reservoirs and shallow-out sand reservoirs, reducing the exploration and development costs by hundreds of millions yuan per year; a back-arrange density well survey technique can significantly reduce the risk of naked-eyed radiological well detection operations and break the technical specifications of the industry for cable measurements and drilling with “two-hundred” measurements, with innovative acquisition of the international conference on marine oil technology award 2024。
“at present, the `specified' system has developed from conventional to non-conventional reservoirs, from constant to high temperatures, from medium to high to low seepage, from shallow to deep reservoirs ” full coverage ', with total technological strength entering the world's first tier, and some technologies have achieved international leadership.” the chief engineer of the oil suit told the cover journalist。
To date, the system has received the national prize for scientific and technological progress, with 217 patents, 56 standards for distribution, and a complete industrial chain covering 52 types and 161 types of instruments. Over the past five years, the “silent” system has been operating almost 30,000 wells, contributing to an additional 731 million tons of oil equivalent, contributing an average annual economic value of over $3 billion, which is important for achieving increased production of hydrocarbon resources and securing energy supplies。
In recent years, the system has helped countries such as iraq, indonesia and uganda to address complex geological orientation operational challenges on several occasions. At present, the “twilight” series of instruments have accumulated nearly 500 million rmb for sale to countries and regions such as india, the middle east, south-east asia, the americas and europe, providing china's unique solution to marine hydrocarbon exploration and development in a growing number of countries along its borders, and promoting external cooperation in the field of energy to a deep, broad and high quality。
China's director-general of sea oil informed the cover journalists that the “single” system is a major scientific and technological achievement of china's deep implementation of its national innovation-driven development strategy, vigorously developing new qualitative productivity and continuously enhancing scientific and technological innovation. China's sea oils will accelerate the development of new quality productivity for marine energy, strive to become the most reliable national strategic scientific and technological force in the marine hydrocarbon sector and make a new and greater contribution to safeguarding national energy security and building ocean power。
