Abstract: The project of geological survey of unconventional oil and gas was organized by the Oil and Gas Survey of the China Geological Survey. And a series of projects were carried out in this project, including geological survey of coal bed methane in Jixi Basin of Heilongjiang Province, the geological survey of oil shale in Songliao Basin and its surrounding areas, the in-situ test production of oil sands in the western slope of Songliao Basin, the geological survey of continental natural gas hydrate, the construction of the Muli natural gas hydrate field observation station in Qilian Mountains, the geological survey of helium in Guanzhong area of Shanxi Province and national survey of unconventional oil and gas resources, and a large quantity of basic data were acquired. Besides, a series of breakthrough and important progress have been achieved in well Heijidi-1, well Heijidi-3 and well Heijidi-4, and the potential of unconventional oil and gas resources in China has been known preliminarily, such as oil shale, oil sands, continental natural gas hydrate, helium, and coal bed methane in Jixi Basin. The project has an important impact in the fields of coalbed methane, oil shale, helium, etc., which has boosted confidence in unconventional oil and gas exploration and development, and promoted the deep integration of scientific and technological innovation and geological survey, and furthered the development of unconventional oil and gas discipline.
