The theory of oil and gas geology and exploration in superimposed basins is the next generation of comprehensive exploration theory in China

In 1984, Mr.
Zhu Xia systematically discussed the relationship between excessive rotational tectonic movement and oil-bearing basins
.
Mr.
Huang Jiqing put forward the "multi-spin gyration theory" of China's geotectonics, and his student Mr.
Ren Jishun has also repeatedly discussed the geotectonic background of China's "multi-spin gyration superimposed basin" and made an analogy
with the world's oil-bearing and gas-bearing basins.
Zhu Xia insists that "on a broader scale, a comprehensive evaluation of hydrocarbon conditions based on the history of multi-cyclic motion and global evolution is carried out with a view to finding new gyration basins in new 'unknown' areas"
.
This view has become the consensus
of petroleum geology workers in China.

In 2005, Academician Jia Chengzao said in the monograph "China's Petroleum Geology Theory and Onshore Oil and Gas Exploration Strategy in the Early 21st Century" that the new generation of petroleum geology theory should have 6 characteristics:

1) The inheritance and development of the theory of hydrocarbon generation in the basin of eastern continental lakes and the theory of complex oil and gas agglomeration zone;

2) The comprehensive theory of oil and gas exploration can reflect the diversity, complexity and exploration pertinence of China's oil and gas basins, not just a reflection of a single discipline or a single theory;

3) Face and answer new challenges and new questions in geological theory raised by China's oil and gas exploration in the early 21st century;

4) Focusing on the new discoveries and new understandings of lithology, foreland and deep oil and gas exploration practices in the east and west of China in recent years, especially the major breakthroughs in natural gas exploration in the central and western basins and the new progress in the exploration of lithology-stratigraphic oil and gas reservoirs in the eastern basin;

5) Draw on the major progress of basic petroleum geology research in recent years, including the research progress of basic disciplines such as basin structure, sedimentary and reservoir, sequence strata, and organic geochemistry;

6) The common crystallization
of the wisdom of China's petroleum exploration and scientific researchers.
Therefore, the oil and gas geological theory of China's superimposed basins or multi-spin superimposed basins has such the above characteristics, which condenses the painstaking efforts
of the majority of petroleum geology workers.

The theory of oil and gas geology in the superimposed basin is the crystallization of the exploration practice and theoretical exploration of China's petroleum geology workers in the past half century, especially in the past 30 years, and is guiding the oil and gas exploration practice
in China.
The application of this theory will add time factors on the basis of three-dimensional exploration and become a "four-dimensional exploration theory"
.
It is applied
in five major fields such as stratigraphic oil and gas reservoirs, unconventional oil and gas reservoirs, deep, sea area, and oil-rich and gas-rich depressions.
Deep exploration will make large-scale discoveries
in the fields of foreland (such as the deep Kuqa Depression), carbonate rocks (such as Anyue, Tahe, Jingbian and other oil and gas fields), and oil-rich and gas-rich depressions (such as Jiyang, Qikou, Mahu and other depressions).

As a new generation of petroleum geology theory, for a long time to come, China's petroleum geology workers will gradually condense and improve, test and rise, further analyze the emerging new fields, and gradually systematize the theory, making it more holistic, dynamic and hierarchical
.
The major contribution of China's petroleum community to the world's petroleum geology will also lead to greater discoveries
