When was the largest oil field discovered in China since the founding of New China? Where is it?

Daqing Oilfield was the largest oil region in China in 1960s and 1980s. Located in the middle of Songliao Plain, Binzhou Railway runs through the middle of the oilfield. Among them, Daqing Oilfield is a large anticline structural reservoir with Lamadian, Sarthou and Xingshugang high points from north to south. The reservoir is Mesozoic continental Cretaceous sandstone with a depth of 900-1200m and medium permeability. Crude oil is mainly paraffin, which has the characteristics of high wax content (20% ~ 30%), high freezing point (25℃ ~ 30℃), high viscosity (ground viscosity 35) and low sulfur content (below 0. 1%). The specific gravity of crude oil is 0.83 ~ 0.86. 1959, the first oil well was drilled in Gaotaizi Oilfield; 1960, in March, Daqing Oilfield was put into development and construction. Since 1976, the annual output of crude oil has been above 50 million tons, and the oil output of 1983 was 52.35 million tons. The discovery and development of Daqing oil region confirmed that continental strata can generate oil and form large oil fields, thus enriching and developing the theory of petroleum geology, changing the backward appearance of China's petroleum industry and having a great impact on the industrial development of China.

Daqing Oilfield is the largest oilfield in China at present, which was put into development and construction on 1960. It consists of 48 oil and gas fields with different scales, including Sarthou, Xingshugang, Lamadian and Chaoyanggou, covering an area of about 6,000 square kilometers. The exploration scope mainly includes the northeast and northwest exploration areas, covering 14 basins, with a registered exploration area of 230,000 square kilometers. Since 1960 oilfield was put into development and construction, the accumulated proven petroleum geological reserves were 5.67 billion tons, and the total crude oil output was182/kloc-0.00 million tons, accounting for 47% of the total onshore oil output in the same period. The proven geological reserves of natural gas are 54.82 billion cubic meters, and all kinds of funds are paid to bear the crude oil price difference of more than 654.38+0 trillion yuan. In particular, it has achieved an annual output of 50 million tons of crude oil for 27 consecutive years, creating a miracle in the history of world oil field development.
