On May 26, 2018, the China Geological Survey of the Ministry of Natural Resources announced to the public the "deep into the depths of the earth" - the major achievements of the deep scientific drilling project in the Songliao Basin. The current depth of completion of “Songke Erjing†has made it the deepest continental scientific drilling implemented in Asian countries. Of course, the major results of this release are not so simple as “depthâ€. The whole project has overcome major technical problems such as ultra-high temperature drilling and large-diameter coring, and promoted independent innovation of core technologies. It has achieved many breakthroughs in mainland scientific drilling technology, and the 4.15 million sets of 24TB deep experimental data obtained by the project will be Become the "golden key" to open the mysteries of the deep earth. 
"Songke Erjing" panoramic "Songke Erjing" panorama, then "Songke Erjing" is a flaw? Why do we have to march deep into the earth? Will we continue to drill in the future? Let's take a look! "Song Ke Erjing" is a slap? “Songke Erjing†is a deep scientific drilling project in the Songliao Basin organized by the China Geological Survey of the Ministry of Natural Resources. It has a depth of 7018 meters and is the deepest continental scientific drilling implemented by Asian countries. It is also the International Continental Scientific Drilling Program (ICDP). Established the deepest drilling in 22 years. The project has exceeded the predetermined target and achieved major breakthroughs in theory, technology, engineering and equipment. It has laid a solid foundation for preempting the international commanding heights of deep drilling technology, safeguarding national energy security, building “100-year-old celebration†and implementing “revitalizing the Northeast. The "industrial base" strategy is of great significance. Why do we have to march deep into the earth? Once upon a time, "the last nine days of the moon, the next five oceans to catch the cockroaches" has always been the dream of human beings to explore nature. Today, human space probes have left footprints in space, and deep submersibles have repeatedly broken through the extreme depth of the ocean floor. However, compared to “Going to the Seaâ€, the journey of human “landing†is difficult due to the blockage of the earth's crust. What is the depth of the earth? It has always attracted scientists to explore tirelessly. The most direct, effective and reliable way to detect the internal structure and material composition of the Earth is to drill a scientific drilling well into the depths of the Earth, extending the human "line of sight" to the interior of the Earth for several kilometers or even tens of thousands of meters. And then find out. Through scientific drilling, in geology, we can study the deep structure and evolution of the Earth, the deep fluids of the Earth and their effects, and verify the results of geophysical exploration. In the development and utilization of resources and energy, we can study the theory of mineralization, the genesis of oil and gas, investigation and development. Deep thermal energy; in environmental science, we can study the causes of earthquakes, the mechanism of volcanic eruptions, the warning of geological hazards, the evolution of the Earth's climate, and the history of life evolution. Therefore, scientific drilling is hailed as a "telescope" for understanding the information inside the Earth.

What scientific achievements have been made in the "Songke Erjing " memorabilia "Songke Erjing " memorabilia "Songke Erjing"? 1. It is found that the two clean energy sources in the deep part of the Songliao Basin have good exploration and development prospects and fully reveal the potential of deep shale gas resources. In the deep sag zone of the Songliao Basin, the Shahezi Formation and the Huoshiling Formation (3350 m deep) found 43 layers of shale gas and gas anomaly, with a cumulative thickness of 102 m, and methane accounted for 86% of the total content of total hydrocarbon components. The average ratio to the background value is 14.77, confirming the existence of favorable shale gas strata in the deep Songliao Basin. For the first time, basin-type dry hot rock formations with development conditions were discovered. In the well depth of 4400 m - 7018 m, a high temperature dry hot rock body with a temperature of 150 ° C ~ 240 ° C and two layers of high radioactive element anomalous stratum were found, with a heat flow value of 84 mW / m 2 , demonstrating good geothermal energy development in the Songliao Basin. Application potential.

Three important evidences for the evolution of Cretaceous terrestrial paleoclimatic climate have achieved a fine characterization of the centimeter-high resolution of the most complete and continuous continental strata in the Cretaceous . The important geological history archives of the Cretaceous stratigraphic evolution were established. The Cretaceous continental history of the Cretaceous from 100 million to 100,000 years was reconstructed, and the main controlling factors of terrestrial climate change at various time scales were discovered. New evidence has been found in the evolution mechanism of greenhouse climatic conditions; important events of Cretaceous climate fluctuations have been discovered, and important information about the large-scale volcanic eruption of carbon dioxide triggering violent fluctuations in terrestrial climate has been identified, confirming that rapid climate change is the predisposing factor leading to the extinction of dinosaurs. . 3. Three major advances in basic geological research have been made to establish a complete standard section of the continental stratum of the Songliao Basin, and a “golden pillar†for stratigraphic correlation has been established; a new evolution model of the Songliao Basin has been established; The new evidence of sub- and short-term transgression events enriches the Cretaceous continental oil generation theory and has important guiding significance for deep oil and gas exploration in the Songliao Basin. What technological breakthroughs have been achieved by “Songke Erjing� 1. Innovated the ultra-deep well large-caliber coring technology system for the first time in the world to develop and successfully apply 311mm large-caliber one-hearted well-forming technology; hollow bottom-bottom power rope coring, mechanically assisted non-destructive core technology; developed a series of large diameter long Drilling core drilling tools and series of domestic turbo drilling tools. 
The KT series of long-drilled core drilling tools developed by KT series long-drilling core drilling tools has been developed. 2. The world record of drilling and coring technology has been created. The record of 311mm caliber single-pass core length is 30m; the creation of 216mm The caliber is recorded at a depth of 4,700m in the well and the length of the single core is 41m.

Drilling fluid circulation diagram Drilling fluid circulation diagram "Entering the ground" is difficult to "God", we will continue to "deep drilling" in the future! There are many world-class problems encountered in scientific drilling, including the “three highs†(high temperature, high pressure, high ground stress) of the earth. Under the "three high" conditions, can the accessories and electronic components of the rig work normally? Secondly, under this condition, the rock in the shaft wall is easily broken, resulting in downhole accidents such as collapse of the well wall and stuck drilling. Finally, from the surface to several kilometers deep, the slope of the well cannot exceed 18 degrees. This is a world-class problem that restricts scientific drilling because it cannot effectively detect the occurrence of well deviation. Therefore, on the surface, it is a well, but in fact it is testing the economic strength of a country, the strength of basic industries and the development level of the entire technology. For more than half a century, scientific drilling has brought people questions and surprises again and again, and has made major breakthroughs in earth sciences again and again, opening up new avenues for human beings to understand the Earth, study Earth changes and explore various resources. The high level of research results obtained by China in international scientific drilling projects has received widespread attention and high appraisal in relevant international fields. With the enhancement of China's scientific and technological strength, scientists will continue to "deeply drill", do more exploration in accordance with national goals, and lead the development of world earth science!
