What important events has been experienced in the establishment of the theory of oil and gas geology in superimposed basins?

The theory of oil and gas geology in China's superimposed basins has experienced the joint efforts and arduous practice of three generations of petroleum geologists, and is the common crystallization
of the research of petroleum geologists in China.
In this complex process of practice, there are some epoch-making events that guide the establishment and development
of theory.

First of all, the "Battle of Tarim Oil", which began in April 1989, began the overall oil and gas exploration
of China's largest sedimentary basin.
In 1983, the Petroleum Geophysical Survey cooperated with the French Geophysical Company to complete 13 seismic reflection profiles across the Taklamakan Desert
.
In 1990, the Tarim Petroleum Exploration and Development Command, in cooperation with the China Earthquake Administration, completed three conversion wave bathymetric profiles of the north-south transverse basin, which revealed the overall geological structure of the basin, and realized that "the Tarim Basin is a large superimposed composite basin" through the "Eighth Five-Year Plan" and "Ninth Five-Year Plan"
national scientific and technological research 。 In 1992, Xinjiang Science and Technology and Health Publishing House published the "Proceedings of Oil and Gas Exploration in the Tarim Basin", in which a series of articles by Tong Xiaoguang, Liang Digang, Jia Chengzao and others on the geological structure, plate tectonic evolution, oil and gas bearing properties of the Tarim Basin were included, which fully revealed the superposition and composite properties of the basin, and became the guiding ideology of the future oil and gas exploration in the basin, laying an important foundation for the future discovery of natural gas in the foreland area and the discovery of the carbonate rock large oilfield in the Taiwan Basin
。

Secondly, the implementation of the ten scientific exploration well projects in China from the late 1980s to the mid-1990s played a key role
in promoting the exploration of new areas, new strata and new fields in China's sedimentary basins 。 The first Kechuan well is the Taisan 1 well located in the Tuha Basin, which produced 24.
2 cubic meters of oil per day in February 1989, and the breakthrough led to the oil exploration of the Tuha Basin and the Jurassic system in the northwest region; the second Kechuan well is the Shaanxi Ginseng 1 well located in the Ordos Basin, which obtained a daily output of 283,000 cubic meters of natural gas after acidification in the Majiagou Formation at the top of the Ordovician system in June 1989, revealing the favorable accumulation combination of the Paleozoic Basin, thus opening up a new field of gas search in the Shaanxi-Gansu-Ningxia Basin, and also opening up a new field of gas in the northern Paleozoic region
。 These new discoveries reveal new layers of oil and gas accumulation in superimposed basins, greatly expanding the thinking
of oil and gas explorers.

In addition, in 2002, Mr.
Li Desheng published "Tectonics of China's Oil-bearing Basins", and Zhao Wenzhi et al.
published the monograph "China's Marine Petroleum Geology and Superimposed Oil-bearing Basins", which systematically discussed the tectonic types and oil-gas properties of superimposed basins, which can be used as a symbol
of this stage.
