The Songliao Basin experienced massive oil and gas exploration and development in the 1950s. In 1959, industrial oil flows were successively obtained from well Songji-3 and Fu-27 in Daqing. This not only commenced the oilfield development of the basin, but also ushered in a new era in the growth of China's petroleum industry. After more than half a century of development, the basin has become one of the most important oil-producing regions in China.
Discovered in 1959 and put into development in 1960, Daqing oilfield is the largest oilfield of China and one of the few super large sandstone oilfields in the world. It is located in the mid-western part of Heilongjiang Province and the northern part of the Songhuajiang-Nenjiang Plain, and consists of 52 oil and gas fields such as Saertu, Xingshugang, Lamadian and Chaoyanggou across an area of 6,000 km2.
The discovery and development of the Daqing Oilfield proves that terrestrial strata did generate oil and give birth to large oilfields. This not only introduced a new domain and thrust to the theory of petroleum geology, but also vitalized China's petroleum industry and greatly affected its industrial development. By the end of 2009, the oilfield had produced 2 billion metric tons of crude and the recovery rate of its major oilfields had exceeded 50%, 10-15% higher than any other oilfield of the same type at home and abroad. The field has produced more than 50 million tons of oil in each of the 27 years after 1976, and more than 40 million tons in each of the 8 years that followed, a miracle in the development history of similar oilfields in the world.
