Where is the most oil in China?

Songliao Basin is the most important petroliferous basin in China, and its exploration began at 1955. The deep oil-bearing assemblage in Songliao Basin is Nong 'an oil layer, the lower oil-bearing assemblage is Fuyu and Yangdachengzi oil layers, the middle oil-bearing assemblage is Sarthou oil layer, Putaohua oil layer and Gaotaizi oil layer, and the upper oil-bearing assemblage is Hei Di Miao oil layer.

2. Bohai Bay Basin

Bohai Bay Basin is an important oil-bearing basin in eastern China, with the total oil and gas output ranking first in China. Bohai Bay Basin is a Mesozoic-Cenozoic superimposed rift basin developed on the basis of the eastern platform of North China Craton, which is the product of the destruction of North China Craton and an important geological event symbol of the destruction of North China Craton.

3. Ordos Basin

The proven petroleum geological reserves and the average annual growth rate of oil production in Ordos Basin rank first in China, with the newly-increased proven petroleum geological reserves exceeding 654.38 billion tons every year. It is the most favorable and realistic area to establish an oil production base. In 2002, the oil production of the whole basin was more than 0/20,000 tons, and in 2007 it was 20 million tons (including extension).

4. Qaidam Basin

Qinghai Petroleum Administration Bureau (hereinafter referred to as Qinghai Oilfield) is one of the earliest developed oilfields in China. Qaidam Basin is located in the Qinghai-Tibet Plateau and the northwest of Qinghai Province. It is an important oil production and supply base in Qinghai Province and Tibet Province. The main production and working area is located in Qingdao, which is known as the "cornucopia".

5. Tarim Basin

Tarim Basin is the largest oil-bearing sedimentary basin in China. At present, the total proven oil and gas resources are about 654.38+0.6 billion tons of oil equivalent, which is called the strategic replacement area of China Petroleum in the 2654.38+0 century by geologists.

Oil and gas exploration in Tarim Basin began at 1952 Sino-Soviet Petroleum Co., Ltd. After Tarim Oilfield 1989 was completed and put into production, it gradually became the energy economic center in western China. The output of crude oil is increasing, and the output of natural gas has soared from about 65.438+0.40 billion cubic meters in 2004 to 65.438+0.865438+0 billion cubic meters in 2009, making it one of the main gas sources of "West-to-East Gas Transmission".
